& TRICKS - How
to make your helicopter "softer" with a DX6i or similar
fairly new pilots choose to purchase a better radio system than those
provided by the likes of Esky and some others. However, these radios
have a great many options, and can be really confusing to setup just to
get the helicopter to fly normally.
are many tutorials on setting the radio up, including one on the Tutorials
page of this web site, so don't try to guess, read a tutorial,
or even several.
when you have done so, you may still find that your helicopter is too
twitchy for many pilots, especially when used with electric helicopters
and by learner pilots.
are however two quite easy things you can do to "soften" the
helicopter down, which is especially useful if you are still learning to
instructions below all apply to the DX6i , but most radios will be very
to the Adjust menu and then select the swash mix option.
will find three settings there, to allow you to change the Aileron,
Elevator and Pitch settings.
your helicopter climbs and descends to quickly, making it harder to
control altitude, then the setting you want to change is that for
PITCH. Just REDUCE the value in steps of about 10 until the pitch
calms down to suit you.
the cyclic controls are too twitchy, then do the same for the AILERON
and ELEVATOR settings.
sure you note that some are positive and others may be negative values,
but reducing them is to lessen the number shown, while keeping the same
+ or - sign.
you have the swash mix about right, you can soften the cyclic controls
so that the stick movement around the centre position makes less changes
to the servos, and then increases the more stick you apply. This
is called Expo (Exponential).
go to the Adjust menu, and select the D/R&EXPO settings.
should not need to change the rudder setting, but you make the first
numbers a value of say -20% & the second number reduced to 80% this
will make the helicopter far less responsive to SMALL stick
movements. Note that we have the same difference in values (20).
radios use positive values to increase centre point expo, so please
check your radio documentation to make sure you apply it the correct
is pretty easy to test this by setting the elevator or aileron to say
-50 and 50 and then watch the movement of the swash when you move the
stick just a little bit forward and back. If the swash plate
hardly moves, you are setting the Expo the correct way.
may still need to experiment with these settings, or the combination of
them, but they are a great way to make your helicopter more
