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.

Vineet

Interesting!!

All the best Dharmik, will be looking forward to this

- 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!! 

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.

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.
