trex 600 nitro fitted with the century diamond series five bladed main rotor system and century's 4 bladed tail rotor system as well. this heli is being prepared for a century 50 size MD500E fuselage. the flight test was done with no stabilization system at all. tried hooking an SK360 but unsucessful so i unhooked it and set it up without it.
