Chapter 22. Tweaking Helicopter Twitchiness

22.1. Reduce the headspeed (CP helis only)
22.2. Reduce the swashplate mixing
22.3. Increase exponential on aileron/elevator
22.4. Add flybar weights or use heavier paddles

As a beginner, you may find that your helicopter is much too twitchy to comfortably learn hovering. Here are some tips to reduce the cyclic sensitivity and make hovering easier:

(Note that you can reverse any of these actions to increase the cyclic sensitivity for aerobatics later when you're ready, e.g. increase headspeed, increase swashplate mixing, decrease exponential, lighten the flybar paddles, etc.)

Be careful when using any of the following methods to reduce twitchines, because they reduce control authority. If you reduce control authority too much, you may not have enough control to preven the helicopter from crashing if a gust of wind occurs. Be sure to apply these methods in small increments to check the effects on control authority.

22.1. Reduce the headspeed (CP helis only)

Reducing the headspeed is good for multiple reasons; it gives longer flight times, and reduces damage if a crash occurs. Most non-micro helis are comfortably flyable down to about 1400 rpm of headspeed. Be sure to leave enough "climb-out" so you can correct a bad mistake.
