DIY Arducopter with QR X350 body shell frame

I decided to build a new DIY drone, after my previous $10 balsa quad was flying (still fly) successfuly for me. And is still doing her job for aerial panoramas as you can see on AerialTasks. That will be converted into an X8, by adding another 4 motors on the samed frame, for a bigger camera.

This time I decided to go with am existent shell body frame and I optioned to use the QR X350 which is $30. It is the same size as Phantom.

You can see below step by step the progress with this quad.

It is designated to load a Hero3 with Tarot for FPV also (new pictures will follow soon with FPV gimbal).

Hope this is job which could inspire some other guys.

I am in the process of tuning this new quad.

Really nice build. I would however ditch those motors with their collet style prop attachment. I had major issues with these motors until I ditched them. SunnySky x2212 980kv (with 3S bat) would be an excellent upgrade over what you have there.

Actually, what size props are they? 4S might be the go.

Very nice!

I am thinking about moving the electronics from my LotusRC T380 to a different frame. The current frame bends all the time I land to hard. 

Do you have any dimensional information about the space in the frame and the spacing of the pcb holders?

@Quazimodo: Thanks for reply. I never had problems with those motors, I did use them on my old H frame (see link) and works fine. Keeping same type of motor between 2 models is easier for me as maintenance or part replacement until ordering others. Also the price for  SunnySky x2212 980kv is more than double comparing to mine. Props in this 350 model are 9x5

@CashingDutchman. I do not have the dimensions, but when I will re-open the model I will measure. Do you use APM on your LotusRC? If want to use APM with this X350, is better the 90 degree pins on APM instead of straight. But both works OK. Maybe I will put telemetry and minimOSD inside and I will open the body and measure the distance.

@Criro1999: No, I am using the electronics that came with the LotusRC. I have not yet considered to use APM, but I might in the future.

CDs seem to be a popular building material on quadcopters.  

I don't know if you have the collets pushed all the way down in your images, but if you do I would recommend cutting the shafts down or replacing them with shorter ones. I haven't had any bent shafts since I cut mine. But you probably don't crash as often as I do :)

Neat build nonetheless.

Indeed, CDs contains a 'silver' layer which is a good RF shield between Lipo below and electronics on the other side.

Hi criro,

This is a really nice project.

It shows a really innovative use of an off the shelf copter frame to make your own copter.

It should serve as a template to others desiring to do so.

Would you mind if I included it on my dronesarefun.com informational website?

Happy to collaborate with you regarding instructional text as well.

Best Regards,

Gary

How is the heat management of the Quatro ESC that you are using as it's installed? I'm using a similar and know that even in the open air it doesn't get 'hot' but it does get quite warm even when pulling about 10-12 amps per motor.
