Choppers are my original interest.. So here is a thread for anyone to talk rotor-craft and any-thing at all related to rotor-craft.. Setup etc etc
***************************
Just some tips and things I have learned along the way that may help..
Feel free to correct or embellish..
Setting Pitch =
1 - Go into Throttle-Hold/Idle Up mode. This gives you your full range of pitch. (Normal mode usually starts at about 40% pitch as you don't want full negative pitch to slam your bird down into the ground)
2 - Go to 50% throttle and make sure all your 3 servo arms that work the swash are at 90Degrees to servo bodies.
3 - Level your swash mechanically using your swash leveler tool, your eye or preferred method.
4 - Still at 50% throttle adjust your linkages from swash to head until you have ZERO degrees pitch with your pitch Gauge.
5 - You should have about 9-11 Degrees pitch positive and negative.
6 - *Digital TX Only * Adjust your swash mix 'PITCH' until have enough pitch range. Anything closer to 100 will increase pitch range.
Setting Tail Rotor =
Struggling here. Can't get her to stop spinning since changing to CNC tail. It is the standard Belt CP rate Gyro. HK HeadLock Gyro on order, hopefully this will help.
Any other idea's? (Gyro in normal mode spins clockwise, in reverse mode, spins anti-clockwise)
When figured out will update this section with actual useful tips on tail rotor.
