MODEL

Select function opens a model memory for control of a model

or adjustment of saved settings. If you haven’t programmed a

model memory, all settings will be at factory default.

CAUTION: Do NOT change the model in Model

Select while operating a model. Change of the model

interrupts transmitter signal to the receiver and may

cause a crash.

A Model name (programmable in Name Screen).

B Model memory number (20 available).

REVERSE

The Reverse function (also known as servo reversing) establishes

the servo’s direction relative to the channel’s input (e.g., a right

steering input should result in a right steering angle at the

model). Reverse is available on all channels and is normally the

ﬁrst function that is checked and adjusted during programming.

Movement of a control or switch is NOT changed. Instead, a

channel’s response to transmitter input is reversed.

Tip: Your model manual may refer to this as changing

transmitter control directions in the Control Test/Reverse Controls

section.

NOTICE: Always check the control directions at the extents of

travel to be sure the linkages do not bind. Travel values that

are too high will cause binding, which may result in damage

to the vehicle.
