Scale Helicopter, the Bell UH-1 Huey

HeliArtist - BELL UH1 Huey

Ready for the first TEST Flight but unfortunately this test didn't go to plan. I found the bird needed a 3-Axis GYRO for stabilization. Current status: A work in progress until the electronic stabilization is purchased. An alternate option would be to install the Trex 450 Main Rotor with it's Fly-bar stabilization. 

Tail Riser Assembly
: Plastic Idler pulleys needed replacing with a metal (CNC) pulley. Plastic pulleys as supplied are known to wear tail drive belts prematurely therefor the preemptive pulley replacement as shown in the next image.
