Servo types

The help for this page of the Version 2 transmitter, in its newest words. A transmitter on V2 B92 or older shows older words.

On the transmitter: Model setupOptionsServo types

For servos that need a pulse rate (Hz) or a centre pulse (us, microseconds) other than the usual 50 Hz and 1500 us.
Check the servo's instructions for the right values.

Touch a box to type a new value.
'Defaults' sets 50 Hz and 1500 us on every channel.
'OK' saves the values, sends them to the receiver and goes to the Front screen.
They are sent again each time the model connects.

These are for the servo outputs of a Version 1 receiver.
A Version 2 receiver ignores them.

Shared timers

Pairs marked * or ** share one timer in the receiver, so each pair runs at one rate.
Channels 3 and 4 are marked *, channels 7 and 10 **.
To give the rudder a different rate from the throttle, move the rudder to another output on the 'Inputs' page.

A centre below 1000 (such as 760) is for narrow-pulse servos.
