Well I used the shapeoko and a 3d printer to make a custom parts that fit the arms of the Turnigy Talon V2. There is a post a couple days ago with a picture of it…
I used the arducoptor APM 2.6 flight controller with an external GPS and a 4 in 1 esc that sits in the center of the frame.
It works real well, the next upgrade I want to do is gimbal and FPV
