Hi, gi1mo2

Times ago, I upgraded my heli: heat sink and carbon tail. After assembled it, I noticed the heli going to foward and drifting to left.
After a lot of work, time and endurance...now it hovering nice. I assembled it wrong and I did small corrections by moving times to up times to down the lower rotor head until to find the correct point and leveled swhasplate as well as did bingo.
