Receiver Dual Rates
The AR635 receiver includes pre-programmed dual rate values that cannot be 
adjusted. We recommend setting your TRANSMITTER dual rate values to 100% 
for both high and low rates. Any TRANSMITTER Dual Rate or Expo values you 
select will be used in addition to the pre-programmed values.
For example, if you select 75% low rate in your transmitter, the actual value will 
be 75% of the low rate value in the receiver.
If you need to adjust the transmitter dual rate, you can do so, as long as the 
value is between 50%–100%. 
IMPORTANT: Transmitter dual rate values must be between 50% and 100% 
for the AS3X system to work correctly. Remember, 50% in the transmitter is 
equal to 50% of the receiver dual rate.
Changing Between High and Low Dual Rates (Flight Modes)
The AR635 receiver uses the Gear channel (Channel 5) to change between High 
and Low Rates (Flight Modes). If you are using a Spektrum DX4e transmitter, you 
will use the ACT/AUX switch to change between High and Low Rates.
•	 Low	Rate	(Gear	switch	0)
•	 High	Rate	(Gear	switch	1)
Sport Aircraft
We recommend using higher gain values for Gear Down (slower air speed). Use 
lower gain values for Gear Up (faster air speed).
3D Aircraft
We recommend using higher gain values for 3D Flight (Slower air speed and 
larger control surface throws). Use lower gain values for General Flight (Faster 
air speed and smaller control surface throws). If you notice the control throws 
on the aircraft are less than you would expect, move the Gear switch to the 
opposite position and check the control throws again.
 CAUTION: The AR635 applies gain values to both High and Low 
Rates (Switch positions 0). You MUST adjust and confirm the gain 
settings in BOTH switch positions. Failure to do so may result in the 
aircraft crashing.
Exponential
We recommend starting with 20% exponential on Aileron, Elevator and Rudder. 
Adjust the exponential value to match your flying style.
