I can't believe i've finished building my very first helicopter and it flies pretty well!
If you found it hard when landing, here is a wheeled landing gear version:

Instructions:
Throttle for power, both the VTOL engine and the double rotors.
You need to throttle up to 90~100% to take off, and 80% to land.

VTOL up 50% slowly and gently for moving forward, remember to pitch hard in order to keep balance!
VTOL down is for stopping in the air, very important when landing.
This XMLed engine is super cool but I forgot where I got it.

Yaw, Trim, Pitch, Roll are the same as normal.

Cruise speed is about 150mph, with VTOL bar 50% up, and trim all the way down. ENJOY
