Instructions

This tricopter is partly 3D printed, partly milled, but u can use laser cut or good old hand work to make the body main parts.
It has hided tail motor tilt mechanism into a tail aluminium pipe, so the tilting servo is on the body and it's moving with small carbon fibre pipe inside that aluminium one. If you use some springs betwen skid legs, you will have good suspension skid system, which will help you to take off.

Used HW: Hextronic DT750 motors
Turnigy Multistar 30 Amps ESC's
KK 2.0 flight controller board
Turnigy nano-tech 4000 mAh 3S batery pack.
9"/5" three bladed propellers
Hitec HS 311 servo.
Orange 6 channel reciever for DSM2 modulation

Make everything as light as it's possible, My one has 1600 grams weight and it is lazy in the air :) Also you will have greater flight time.
