i will prolly be getting a new set which is more powerful for my FPV
so will sell off my OLD SET CHEAP when i decide to do that

heli crashes are unpredictable one laaa .. so parts damage count oso unpredictable ... thing i hate with heli is .. after u fix everything u can SEE DAMAGED and u go fly it and something else comes up .. hahahaha

Dammit... my rotor head screw snapped... rotor fly out... crash!!!

Damage...
1: 1pc hex screw
2: 1 hex bolt/nut
3: Align T head for 450 sport

if your piro rates are slightly different ... adjust your end points
if u have equal travel on both directions and tail blade has no or very little countering pitch when servo is centered then for sure one direction piro will always be faster than the other due to main rotor torque
adjust using your dual rate for rudder .. leave the end point adjustment on the gyro and travel adjust alone

then u have to do the rate mode style rudder setup like for the older gy401

put your gyro into rate mode (gain is same % as your head hold) instead of head hold ... then try and hover your heli
u will find the heli tail wanna swing to the right ie. no countering torque
adjust the linkage to provide more pitch to counter the tail going right ... normally is until about 8 degree pitch (almost impossible to gauge by eye unless u expert) ...
when u can hover the heli in rate mode relatively stable without the tail drifting too much (damm hard to get perfect no drift) and no rudder input correction ... then u are done and no need to adjust radio or any other electronics
put your gyro back into head hold mode ... test your piro and u will see that left and right piro rates will be the same
