You also get a different feel with a different length flybar. Generally speaking, the longer flybar will give you a little more cyclic power because the paddles are moving faster and have more bite. There are limits to this depending on the type of flybar mixing your heli uses.

Higher head speed also increases the cyclic rate.

Lighter blades, and/ or more unstable blades will also increase the cyclic rate. There are limits to all of the above before it becomes a dangerous or unflyable.

Get some light paddles, good light blades, 1850 head speed, and have fun.
