This was my learners quad and it still goes gr8
Built back in 2011

Features:
  • Wooden booms - don't laugh at them!
  • Easy to mount and fix.
  • Cable ties on motors and a plastic food container to house the FC
  • Flies really well and easy to maintain and repair. Actually crash damage is never too much.
  • All motors are now angled 5 degrees into the yaw direction for very positive yaw control.
  • HK450 Heli skid to land on.

Uses old Warthox MultiWiiCopter board with Wii motion gyros, and BM180 accelerometer.

Good value!

My latest Quad

Its a cross between a MultiWiiCopter and the Talon. Scary - maybe. It just evolved that way!

Flys really nice. Using MWC with baro for alt lock.
