Cyclic Travel Limiter

Without cyclic travel limiter, the maximum cyclic deflection is when you hold the stick in the corner (full aileron AND full elevator). Therefore, you can't have full cyclic deflection when you give only full aileron, or only full elevator.
However this situation is not natural, as the cyclic is circular in nature, and the maximum amount of cyclic could be the same in all directions.
To equalize the amount of cyclic in all directions, we use a cyclic travel limiter. Effectively it allows you to increase the cyclic deflection when only full aileron or full elevator is given, by eliminating the nasty corners that would force you to reduce the deflection.

Making a cyclic travel limiter for Futaba FF8 and FF9 is extremely simple. Just get a large Futaba servo wheel, drill a large hole in the middle using a 22mm wood drill and click it in place. Fits perfect, not even glue needed!


Remember to use little or no exponential, otherwise the cyclic travel limiter may not function as intended. See my tip on this.

There are other solutions, but I think this is the best one so far:
* Stick length does NOT matter, you can change the stick length at any time without need to modify the limiter
* Clicks straight on of off into my FF8, nothing double stick tape or so. Not even needed to unscrew part of the stick.
* Does not modify the transmitter.
* Sturdy, you can't break a transmitter wheel by pushing hard into the corner (I suspect that the stick will break first).
* Costs $0
* But most importantly, the wheel is really round. Other solutions like wheels attached to the stick will ride a bit bumpy at the extremes, because the transmitter surface is not flat under the stick.
