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.
