Tricopter v1.0

A recent Tricopter design by me. The frame is designed with 3 slots for interchangeable modules. This frame isn't the lightest out there but is very strong and assembles easly I have included a Gopro mount for the front slot. I wonder what other modules people will design for it? The tail yaw mechanism uses a standard aluminum spacer from home depot and a bolt as the axle. I use 14mm carbon fiber tubes for the arms. Motor mount holes are 19mm and 16mm and fit my NTM motors. Also included are small mounts for your receiver, speed controllers, video tx, ect. The cockpit is sized to hold a Ardupilot perfectly. I used foam mounting tape to attach the cockpit to the main frame and another layer of mounting tape to attach the Ardupilot to the cockpit, This reduces the vibrations seen by the controller significantly.
