How much cyclic pitch are you guys gettings from your 30-50 size helis?

I have a Kinetic 50 and with the collective at 50% (0 degrees pitch) I measure 5 degree of cyclic pitch for both the aileron and the elevator. I can get more by increasing the ATV for these servos but if I do this, it causes a bind at +/- collective pitch.

The bind is not bad when adding in only pure elevator or pure aileron. But... start to move the cyclic stick to the corners, mixing in all control elements, elevator, aileron, and collective (-9/+10), the washout ball links hit the main rotor block just above the guide pins creating a nasty bind!


Is 5 degrees of cyclic pitch a reasonable amount for loops and rolls?

I have been settings up a Skookum sk360 virtual flybar on one of my 450 class helis. For proper function of that unit, installation requires 8 degree of cyclic pitch. I realize that without the flybar and everything that goes along with it, it is possible to get insane levels of pitch. All of this though, has me wondering how much is enough?

Alot of great info in a very concise read.

5 degrees of cyclic is morre then enough to do rolls and loops....head speed is more important for faster cyclic response as is cyclic to throttle mixing. Of not is that you should be able to easily get 6 degrees of cyclic.

Since the Kinetic 50 uses the same control system and a similar rotor head to the older Century Falcon 50, I would suggest you give a good read to this set-up sticky by SteveH on RR. It should answere all your questions and get you well on your way.

GyroAl,

Thanks for help! I am printing it out now.
