Tail Rotor

[MikeB]

I have question on setting up my tail rotor on my Predator Max. I have the upgraded forward mounting servo, which I have installed with the carbon fiber rod from servo to bellcrank. The question I have is: I have to cut the carbon fiber rod from bellcrank to tail rotor. I don't know how long it should be. Should the tail rotor blade travel be in the middle, or should I allow some pitch in the tail rotor blades with the rudder servo arm at 90 degrees?


Thanks...

Everything is 90*, no exceptions.
Start your gyro, then change state to normal (not AVCS) and center all trims, subtrims, etc.
Switch off/on and switch again to normal. ( to make sure you are neutral) and with bellcrank on T/R at 90*, mark and cut pushrod.
You should have threads left on the links (each end) to allow shortening if needed, just thread until they stop, and back off 4-5 turns.
Once you test fly, you will have room to adjust mechanically.

LameBird,

Hey thanks, "bellcrank on T/R 90*", that's the piece of information that I needed.

Have a great Christmas...
