After reading hundreds of DIY topics, understanding physics of multirotor and watching FPV videos finally i have designed completely new FPV frame on CAD. At this moment i am working on prototype frame. This is just 50-60% work of my project. Some of the 3-4 exciting features and dimensions are not included in this pic. The frame has plenty of space to put camera, fpv gear and other electronics. One more exciting feature will be custom landing skid which will give it stunning look and smooth landing.

Features to be achieved:
- Spacially designed for FPV, onboard recording, nonFPV quadcopters
- Prop free video
- Front and back camera
- Specially designed landing skid.
- Target weight will be 300-400grams
- Compatible with 8-9 inch props.
- Fully symmetrical on both axis
- Some more features to be shown later.
At this moment it's just on paper design, i will complete prototype soon. I will post final frame dimensions, boom length and nut-bolts placement later.

Nice initiative! A completely indigenous quadcopter frame at last!
Will it be CNCed? Do share more details as and when available. :thumbsup:
Vineet
Interesting!!
All the best Dharmik, will be looking forward to this :thumbsup:

- Fully symmetrical on both axis
I prefer one axis (roll axis) symmetry frames like t-copter, spider quad copter etc. only because they provide better orientation. But I guess it should not be a problem with the big rectangular centre section.
@Vineet bro it will be available to everyone on RCIndia. I will post all my .dwg files with dimensions here so one can easily make that from household items like aluminium booms, plastic, glass fibre or PVC sheets. I will contact Vivek sir if he can make that using CNC at affordable price.
@Dreamfly sir thank you.
@Sunlikestar Sir actually i was working on fusion of QAV500 and HT FPV frames. I designed half of that too but left working on it later. The reason was overall weight and length of arms. It required more material and those expensive frames(quv500 and ht fpv frame) made from light and stiff black G10, milled aluminum, and custom aluminum spacers which i won't able to find and use here and normal plastic or glassfibre sheet material might increase weight so i went with simple frame specially designed by keeping Indian conditions in mind. I am planning to use exam board sheet and 1/2 aluminium arms which are easily available here so everyone on rcindia can make that and fulfill their dreams. All dimensions are allready tested because they are taken from my recent custom frame. This frame will have dual shock absorbers(cricket bat grip) one on arms where they sandwiched between two plates and other underneath the motor mount to reduce vibrations. It has special hooks so one can easily test it on string to get optimum gain on both axis as gain on X and Y axis will be different due to motor distance. Let's see how it goes.
Go! Dharmik Go!. I really like the simplicity of parts and materials. Let's C how it turns out. If you plan on selling one let me know. I would like to test one out. I get frustrated designing my frames sometimes. I takes the whole day or sometimes 2.
Sure sir. I am just worried about spacers and 3mm nut-bolts. I will have to search in every corner of city. They are not easily available here.

I am planning to use exam board sheet
Those plastic types? They seem very brittle! And if you are talking about those brown ones, they are made from cardboard and do not take well to vibrations! If you screw into them, after prolonged use the screws come loose as the paper layers come apart.
I am using those exam boards and I'd say they're an excellent solution. They're made of sw sort of a thermosetting fiber which makes them very strong.
A very nice initiative dharmik bro, go ahead!
Oh! Can you please attach a pic of the board? A close up of some area that has been cut or sanded?
@Dharmik: I really like the shock absorber idea! :)
Hey bro here is the pic. They are available in different thickness and colors.
Even i have used the same board, but this breaks if there is a hard landing. If you have a good landing gears then you should try with it..
Yeah there are so many types of boards available. I saw brittle one too in the stationary. This one has 2mm thickness and not brittle but foldable to some limit. The same thickness plastic sheet i am using in my current frame
Good going Dharmik! I am sure it will be great!
Thank you sir
@Dharmik: HOW did you cut it in that shape?!!? Of course not just hand-tools, right?
That is a good looking frame!! {:)}
Love the heatsink motor mounts!! ;D
have you tried any DEMo from this FRAME ?
@Vineet bro yes they were hand-tools only. I used normal kitchen knife and heated it up on the gas burner and removed rough portion out of the plastic tray and then refined the edges using cutting knife. Please have a look here.

@LastRites haha yeah they are weird, i realized it later when i received motors but still they are doing their job well, never had any issue.
@Swapnil bro that FPV frame is not yet ready, i am busy with some other stuff but it should work as i took enough care while designing it. The dimensions are taken from my current quad frame. I hope i will get other required things from local market.

Nice idea, I'll try it out the next time. ;D
Some updates on this project. I received my FPV gear, thanks to Vineet@HobbySea, first LHS to have fpv stuff. Got few things for frame also. Nowadays busy with job and it keeps me away from all these but i will try to finish it soon.
hey dharmik sir!!!
how much money did u pay for ur new fpc setup/???
after testing it can u plz let us know its range??????
tnq
some updates of this project. Plates are ready and made of exam writing pad.
I have changed few things like dimensions of plates and aluminium booms. Here is the snap how it looks.
Here is one more pic of latest update
wow looks great :)
Great work man, great going .. keep up & keep upload.. {:)} {:)}
Nice workmanship. but that landing gear would make things tougher ie balance during land and takeoff... you should have some support at four arm ends......
regds
Saurabh
some more updates
The frame is ready and successfully flew my new fpv quad today. I will post video soon.
super!!!
looking great
looks awesome, waiting for video..
Great job Dharmik bro!!!
couple of questions.
1) What is length of those long nut bolt?
2) Do you think that you should add some suspension at bottom ? i think with rough landing long screw will bend very easily ?
Atul bro there is a landing skid at the bottom, dharmik bro uses landing skid of the helicopter...

Thank you friends for your input. Actually this video was shot in 720p which was 466MB of size, i had to scale it down. At this moment i am using 450 heli landing skid i recently bought from the RCI user Shannon. The bolts used are 75mm long. I am going to use 5.8GHz starter video link. I will post complete build log and 1st fpv video soon.
Tested fpv gear today.
Here is a short edited video, it touched the ground
http://www.youtube.com/watch?v=wCQweLhd7PU
FPV gear test
http://www.youtube.com/watch?v=51KxI6bYyx0
As i said before I got really amazing performance from hk 5.8ghz 200mW fpv setup. I found some interesting facts of rc305 fpv gear as well. When initially I powered up the setup I just got few feet range. After tuning it properly now it works perfectly. Please have a look at the pic of ground test attached below. You can see there are obstacles between txrx but reception was good enough until the buildings came blocked signal. It started showing white dots on the screen. I am sure the setup can do much more if you fly LOS
EDIT
Red dot shows walking distance not signals path ;)
Dharmik bhai. Is it possible to show how the actual video looks like. This could undoubtedly be my next project.
Yes sir I will try, I want to check the ground range again on the straight road. I saw some posts that fpv is easy compare to Los flying but for but actually it's bit hard specially when you land, have plan of fpv trial at my friend farm
Quote from: Dharmik on February 17, 2013, 09:50:13 PMAfter tuning it properly now it works perfectly
What exactly you mean by tuning bro??
Dharmik bhai, Satya bro, Here is the 1.5V of the KK2 firmware. Great features with gimbal stabilization.
http://www.rcgroups.com/forums/showthread.php?t=1675613
Also here is the video to build your own gimbal.
http://youtu.be/PTzgsmA4Rqc
P.S - Satya bro, i flew my quad with v1.5 without any 'tuning' (Stock Settings). Did not have any problems with oscillations at all!
Cheers! :thumbsup:
I mean channel selection on both tx and rx needs to be correct using trial and error method as docs come with the setup are not true so you need to find correct combination of channel switches to get best out of it, and CP antennas might help as well to go up to 1 to 1.5km
Thank you veloci for the link. I have 1.4 on both quad will upgrade later if gimbal needed.
OK Dharmik bhai. By the way, what material have you used for those center plates?
EDIT - Got it. Thanks!
This is my first fpv test flight over the village farm using 5.8GHz video link ended with the crash, luckily i got everything back without any damage except one broken prop. Learned so many things from this test. Ready for next mission.

Nice stuff bro, i was trying to get the RC305 FPV setup today but was not able to get it work. I was testing at home, connected the AV out from Rx to my TV and the Tx was conneted to 2S and a camera was connected too. But there was no output on TV :headscratch: :headscratch: anyidea what was i missing?
Satya bro use 3s lipo for tx. You can use 2s for rx but i am using 3s for both txrx and it works. I got my camera with wrong polarity cables, so check that too.
Hmmm i will try that and let you know :thumbsup:

Sir,the receiver supply voltage is from 9-12 volts and a 2s is not gonna work.
i tried with my own setup and it doesn't work well. sometimes doesn't even power on. But it worked perfectly fine with a 3s.
Dharmik Bhai, I should say that's the way to go! away from all the hassles and worries. Great Going. Imagine that crash in a crowded place!!!

My Tx was connected to a 12V adapter and Rx was connected to 2S
So you mean RX operating voltage is between 9v-12v??? but the red led on the rx was on..
Yes sir it can be worst if you crash in crowded place. I was lucky this time that I got it back in one piece. It was still sending me video signals from the crash place. I believe this 5.8ghz gear is capable to do much more.

Yes sir, i've tried this and it didn't work for me.
the manual says operating voltage between 9-12 volts.
Satya bro which fpv cam you are using? I am using Sony ccd cam. Feedback over hk website says there is an issue with signal, positive and negative wires. You have to invert two of them to get it work
Well i am using SONY CCD but not from HK from another supplier. How do you know that camera is powered? any light on camera?
Quote from: satyagupta on March 03, 2013, 09:27:35 PM

is it a board camera ???
then you can always use a multimeter.... ;D
Yea its a board cam. How do i use multimeter any video link?? Seesh i never knew connecting camera with tx would be so much pain
check the camera for supply from the smd voltage regulator to the microcontroller supply pin and this should help with the setup..... all the best :thumbsup:
www.youtube.com/watch?v=SFZ3TZLognk
Satya bro do you get any signal or just blank screen? Also make sure channels on both are same. I am tweaking with it, once I get best combination I will let you know btw what does mean board cam?
I just get blank screen, channels are same on both. Sure thanks please let me know.
the SONY CCD CAMERA that you get from HK is called board cam
like this http://www.hobbyking.com/hobbyking/store/__11977__1_3_inch_SONY_CCD_Video_Camera_PAL_.html
I am connecting the av out from rx to my big LCD at home is that ok :headscratch: :headscratch:
I once again try to explain the connections:
RX is connected to 12V adapter and its AV out is connected to my home LCD
TX is connected to 2S for input, i took the voltage using the voltage checker and it read 7.06 V and its VIN was connected to camera http://www.hobbyking.com/hobbyking/store/__11977__1_3_inch_SONY_CCD_Video_Camera_PAL_.html
I got lights on both TX and RX, but on my LCD it used to say no input. But both TX and RX was bit warm after 5 mins of testing. :help: :help:
Will test them with 3S and one a mini TFT LCD
Quote from: satyagupta on March 04, 2013, 08:57:45 AM
TX is connected to 2S for input
Try running It on 3s instead.
1. Connect ccd cam to the tx(don't forget to remove lens cover ), check polarity as well. If you look closely pin out info is printed on the board cam.
2. Connect 3S battery to the tx. You will see the red light below the tx.
3. Now connect AV cable to the rx. Yellow is the one that sends video signals. So connect that only others not necessary.
4. Connect 2s/3s battery to the rx and you will see the red led on.
5. Get any LCD/led TV or monitor and find AV-in port. You just need to connect your yellow cable to the yellow pin. If you connect it to the TV you have to change the mode to AV as it might not show you transmission automatically.
Just make sure always hook the antennas first before you power up your tx or rx.
this is the perfect procedure.
i follow the same steps as described, but remember to power on tx before switching on Rx and Satya sir, 7.06 volts is too low for the setup to operate.
basics of tv videos signals state that a composite video signal voltage ranges from 9-12 volts hence the tx also needs the same amount of voltage to generate that level of signal and further more i think the LED is powering up because the Lipo is capable to provide more than enough power for the controller on the board to switch on. Hope i helped.
Got pair of CP antennas(CL+SPW) from QK. I will try to get data of range test and comparison test.
This is my second FPV flight done at the farm. It was a great fun flying this quadrotor. I am getting 12min of flight time from my 3300mAh lipo with fpv grear and camera, at last battery ran out of juice and quad landed roughly on the field, no damage! I just mixed some footage from the ground and FPV. This time i used CP antennas. I will post detailed review of CP antenna later. Special thanks to Mahendra bhai and Navin bhai to help me find this beautiful place.http://www.youtube.com/watch?v=jPPJN6C4hlk
Wow...Awesome...
(:|~ (:|~
Really cant wait to fly my quad.. dharmik bhai need your help for that.. :)
Dharmik sir, this is great and nicely stable build. Could you help me with tuning PI settings in kk2. I also wanna make mine stable.
Wow so you were flying FPV or LOS?? i tried to fly using FPV (i have a video goggle) but it was very hard to judge the position and i guess i am not used to it so i was not able to control it too :(
But i really want to try FPV. I have one question bro, my quad is not very stable, sometimes there is very low freq oscillation. Can you help me to find it out why?? I tried to increase/decrease PI values but the wobbling is still there.
Quote from: Dharmik on March 26, 2013, 07:21:00 AMI will post detailed review of CP antenna later.
Yea please let me know.
Arun and Rahul sure friends, let me know. Will try if i can help you guys. I am not experienced, still learning all these things. Best way to find PI settings is to get Optimum P(roll/pitch) gain first. I have set mine to 110 but i have flashed my ESCs so quad flies fine on higher gain as well. Satya bro this one was LOS but previous one was pure FPV. Yes it's hard to fly. I think LCD screen might help as you can have both views FPV and LOS together.
Oh I will try the PI settings in my main hexacopter. Because this quad was not a serious project. (THE st360 quad).
i will do everything in hex. Do you think Plush's should be flashed?
HI Rahul, i don't know exactly which plush ESC you have but please have a look at this
https://docs.google.com/spreadsheet/lv?key=0AhR02IDNb7_MdEhfVjk3MkRHVzhKdjU1YzdBQkZZRlE
I am using Plush25A. Dont really understand the worksheet. Does it say it needs to be flashed to simonK? Thanks.
I see two types of ESC listed there. The old one has atmega chip while new one has silabs. Can you take a snap of your esc?
Here is one more FPV video. Got some boys wanted to see how FPV view looks, so i let them see live video feed on the LCD screen. Overall it was a fantastic day. I will go there again to catch some more action once i gain confidence over FPV. Trying to get rid of vibration.

Can some give me Ashta Sir contact No
I have been testing my frame last evening. This is first attempt to get rid of jello effect. I just hard mounted my cam using rubber band and i see huge improvements. After tweaking with few things jello seems to appear less in the fpv video. I will post test video soon.
http://www.youtube.com/watch?v=0lQ66omE9vI
Way to go, dharmik bhai!
I took this video few days ago when i was testing new firmware on KK2 FC. It seems gains were bit low and it was windy that day. It was hard to control the craft. Moreover one prop broke mid air but later everything went smoothly. Now doing some mods to the frame to get better results. The video edited using wondershare editor.
http://www.youtube.com/watch?v=fasvPsGSC_Y
looks quite stable, lots of questions bro,
what camera for recording? quality is good. :thumbsup:
what settings(gains etc) on kk2? version 1.6 or 1.6++?
how much range with the 5.8 ghz u have got so far?
how did the prop break? was it damaged already or out of the blue? its scary.
props il suggest hobbyking soft fly ones. lol. slowly fly actually. i have crashed into walls with it and flown again . they just bend. u can bend it back and use for entire day if needed or maybe weeks. rapid escs are awesome ;D .
Hi Pravesh, i am using HK HD wing cam for recording and sony ccd as a flight cam. I have flashed the board with kk v1.6 fw. I haven't tried 1.6++ but its lit, mid and high SL rate seems to be good for fpv. We drove 15-20kms to the village for fpv flying. We couldn't fly over the farm where we planned before due to tall grass so we flew over their cricket ground. The props i have are gemfan copy. They don't brake easily but that day one prop did it and gave up in the air. It broke from the hub. I quickly replaced it with new unbalanced prop that you see vibes in 2nd part of the vid. The screen i have is too small(4.3"), so planning to get 7" or higher later. I haven't accurately measured the video link yet but we have 2.0km+ straight road in the GIDC where i am planning to test both RC and Video link if i get time.
hi dharmik, thank you for the reply. the good thing bout 1.6++ is u can do flips and stunts and when u leave the sticks it self levels ;D. even im using 1.6, version. planning on 1.6++. 1.5 had a bug where acro mode was not tuneable.
gemfan from bevrc are good. they are thick and stiff and original. or rcdhamaka plastic props which dont break easily.
you can use the same 4.3 screen, make a HMD(head mount display) and put 2x or 3x fresnel lens in it, ul have full immersion it will feel like 12 inch display or bigger, or temporarily u can use 2x reading glass. let no sunlight in. put a DVR if u start getting blue screen due to signal breaks, i dont know but dvr seems to solve it.
im confused about which camera to buy, been looking at 808 #16 camera. but not sure. what would u go for?
I will flash 1.6++ soon. btw can you give me the link of Fresnel lens and 2x reading glass. if you can spend some more then go with explorer HD cam.
{:)} Dharmik bhai!
reading glasses in optical stores. 200rs.
fresnel lens ebay. u can use reading glass till fresnel lens arrive. they are cheap . 5-15$, u can cut it to shape. and buy the book reader size. install them inside HMD. im still searching for fresnel lens locally but no luck so far. probably ebay it.
OMG!! Pravesh bro this Fresnel lens looks interesting stuff. I just searched over eBay and it seems we can also make big screen projector. Thank you very much as didn't know about this thing. So have you tried it for your fpv?
i have tried 2xreading glasses and it will work but have not used for actual fpv flying, i use a 7 inch monitor, going to buy reading glasses tomorrow and will report after flying with it. have to order fresnel lens from ebay. 7 inch monitor HMD is too big.
now i want to get a 3.5inch one or 5inch one and make my own fatsharks with these fresnel lens...lol
fresnel is best as u can install it in HMD(headmountdisplay/homemadedisplaysetup).
there are people using 3.5-5inch monitors(480p) with fresnel lens specially for quads stunt flying. the display will be crisp even on edges.
Here is the test flight of fw v1.6++

FPV EGO - Roaming
I have been testing my quad few days ago inside the room. I have flashed v1.6 on my KK2.0 board. It feels so stable, however it looks like my receiver has some issue. I am planning to replace it soon. Not getting enough time to test my new FPV setup and power dist board but hopefully will do it soon. Right now i want to get rid of my faulty receiver.

dharmik,
what was the PI for this flight. Its look too stable. I think its Self stable enabled flight wht was the self leveling PI.

pravesh you can also get Fresnel lens at a good stationery shop. Ask them for the sheet magnifier. The common ones are 3x and costed me Rs. 200. I still have to make the box though :D
i think u got carried away with the posts, hehe . thank you for the info.
my box was a simple pressure cooker box in which i managed/DIY to fit my head. lens from VC Sir.
the monitors clarity with the 2-3x lens is better than googles image but i use googles cause its not heavy like these, the idea is to keep sunlight out or u will not get the immersive feeling and also curve the lens while installing in box so that the final image is rectangle.

Yes red brick 30a esc can be flashed with simonk, altho they are not very simon k friendly,
Issues have been reported while flashing and after flashing.
A simple google search can give you all the necessary info.
Image attached for pin outs
Sorry aniket did not notice you post :(
Yes you can flash it, why dont you use SimonK ESC dont have to flash it. Its ready to use ;)
I did search... all I found was guides for 20a versions... thanks anyways! :D
satya sir I guess I will... I already have 4 red bricks... so let's see...

Hi Dharmik;
This frame is very nice! Do you have a personal website so we can see more projects from you?
Cheers!
Its a nice LED work. i suggest to get a green laser pointer pen, hook it on your quad vertically, in center, pointing downward and see the magic. it will give an illusion that a stick is holding the quad.
Sandeep
nice idea Sandeep ji :thumbsup: i will surely try it once :giggle:
yes, illusion and blindness. people will look into it, hold it upwards towards the sky keeping the laser beam away from eyes, been there done that.

This time we decided to visit my friend Viral's village. It's really wonderful place having river just behind his house. We hired a boat and went to the beautiful location. We spotted croc as well enjoying sunbath, but as soon as we reached that site it ran into the water, we missed oppertunity to grab it in the video but we found many good shots. The jello was reduced to the great level. I found the secret to get rid of it. I will post on my blog.

thank you VC sir. Just following you and your DIY habit. :)
Hi all, i have been flying my scratch built(self design frame) quad from past few months. I got some really nice footage from this quad and now decided to give it some improvements especially for the frame. My current frame made of plastic exam board sheet which did it job well but it's not sturdy however i don't see any difference during flight but when i hook camera it gives me some vibes and jello effects in my video. So i requested Satya bro(quadkopters.com) to cut frame for me from my cad files. I received my frame yesterday and i was surprised to see how well it was crafted. The material is G10 black 1.5mm thick glassfibre sheet very stiff and sturdy. I see very neat and clean work. I would like to thank Satya bro to help multirotor lovers in real mean. I am sure many people will soon come with their self designed frames. I am now designing one more frame but till now i would like to show some snap of my XtremeX frame got from QK.
Is the 'G10 black glassfibre sheet' same as acrylic sheet?
Yep Satya bro gave me some options to choose from like indian glassfibre, chinese G10 black glassfibre and carbon fibre in 1mm, 1.5mm & 2mm thickness.

Acrylic sheets are made using some plastic. but G10 or Glass Fiber sheets are made using sheets made up of Glass Fiber.
So the G10 must be much more stiff (and heavy) for the same thickness, right?
it indeed is very stiff but not very heavy, but it would be slightly heavy than acrylic sheet
What material would you recommend for a quad frame (other than the G10, that is) ?
@Satya
Dharmik mentioned 'carbon fibre'. How does it differ from glass-fibre in terms of weight, stiffness and cost?
I'm hoping to start designing a quad frame, but I'm not familiar with the afore-mentioned materials.
hmm you can go with the acrylic or thin MDF/Plywood or like dharmik bro did you can use the exam pad.
For my very first quad i used 5mm plywood, was pretty heavy had to cut lot of parts out of it.
I wanted a CNC cut frame from you. What I'm trying to ask is, which is the best material you can provide in terms of stiffness, weight and cost.
this is a glass fiber: http://en.wikipedia.org/wiki/Glass_fiber (http://en.wikipedia.org/wiki/Glass_fiber) using this fiber a sheet is made and using several layers glued with resin, glass fiber plate are made. Number of sheets vary depending on the thickness of the plate.
Similarly this is carbon fiber: http://en.wikipedia.org/wiki/Carbon_(fiber) (http://en.wikipedia.org/wiki/Carbon_(fiber)) and using layers of such sheets glued with resin, Carbon Fiber plate are made.
Glass fiber is good and cheap compared to Carbon fiber.
Carbon fiber are very expensive but at the same time they are very sturdy, stiff and light weight
If you have limited budget then go with glass fiber they are 60-70% cheaper than carbon fiber
I just need drawing of the cutting in dwg or dxf format and i will get it cut. If you want i can send you a estimate pricing just drop a mail to webmaster(at)quadkopters.com with your drawing and thickness of the sheet that you want.
Thank you! I knew what they are, just never worked with them.
Looks like CF is the best option. Could you pm me an approximate cost of the frame Dharmik ordered but in carbon fibre?
Hi Swapnil bro please have a look at this thread regarding the most cost effective flat stock? Fiberglass? G10? ABS? Other?

Dharmik, thank you for the link. Looks like G10 is the most favoured material. I'll go for that.
Hello all,
i have assembled my G10 glassfibre frame received from Satya bro today. i see huge improvements now. it's stiff and sturdy. please have a look at the snaps i got today. planning to install align landing skids but they are bit on heavy side compare to old one. will perform first test flight soon.
After using KK2 for more than 2 years and CC3D on my mini quad Hunter. I have decided to go one step ahead. Now i have plan to test one of the most advanced board APM. I had to made some changes to mount APM on my xtremeX frame, some drilling, cutting and dampening and now it is allmost ready. Detailed review will be posted for CC3D and APM.
Tested APM few days back in stabilize mode. I see huge difference between KK2 SL mode and APM stabilize mode. I am really excited to test other modes.
Loiter mode tested as well and it works fine, however due to very small street it was bit roaming in 1m tolerance. I will upload video soon. Here are some snaps

Nice build. {:)} {:)}
FPV QuadCopter - Boat Filming
Last year i went to my friend's house which is just near the river Narmada. We had a great day filming over the river. In this footage we saw the boat coming towards us, we quickly flew quad over there to grab it in the frames. I was flying LOS and when i landed quad i found that i forgot to switch on the SJ1000. That was a LOL moment. We missed nice footage and battery ran out of juice hovever we got it from the ground from the phone.

My Xtreme quad got new FC NAZA M lite. Here is the test video of GPS position hold. Still some tweaking needed with gain setting

one more test video. same gain just slightly lowered.
