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?

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.

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.

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.

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?

Dharmik

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.

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.

Dharmik

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?

pravesh736

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.

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.


Dharmik

Hi i have fw 1.6 from rc911 with sl med enabled. PI values are 110 and 60 while sl P is 55
