D4 - RADIO - How can I
make my helicopter less twitchy using the radio ?
The answer to
this relies in part on what radio you have.
If we ignore
the basic radios such as the Esky 6 channel, and assume that you
have a computerised radio such as the Spektrum DX6i or similar then
basically 2 areas that you MAY need to setup to get the heli flying
as gently as you want it to fly.
1 - Use the
Travel Adjust menu (End Points as they are sometimes called) to
limit the total aileron and Elevator movement the swash plate can
achieve. When doing this, you need to be aware that with most
radios you need to hold the stick in either direction because you
can set the endpoints for each end separately.
Be a little
careful doing this too much, as you still need to have enough
control of the helicopter to recover it to level flight again if it
gets into an unusual attitude.
2 - Use the
EXPO control. This is usually a part of the D/R (Dual Rate)
setup. Expo adjusts the actual amount of servo movement that
occurs around the centre stick position. By putting a positive
value in expo for Elevator and Aileron, it takes more stick movement
to achieve a given amount of movement of the swash in the relevant
direction. A negative value does the opposite, and makes the
helicopter VERY TWITCHY around the centre point of the cyclic stick.
