For JR 285 Servos
Use the longest side of the four-sided arm with the control ball placed in the mounting hole 12.5mm
from the center.

Use the two-sided arm with the control ball placed in the mounting hole 15.0mm from the center.
9.3 Set the gyro to Standard Rate Mode (non-heading/tail lock mode; see the gyro manual for more
info) and center the rudder stick. The tail servo should be in the neutral position. If you are unsure
of whether your gyro is in the standard rate mode, or if it does not offer a feature that allows it to be
used in a standard rate mode, you can disconnect the gyro from the receiver and plug the tail servo
directly into the rudder channel.
