8. Again use the

Edit Up Down

keys to get to the Expo menu, and set up a desired value of expo

for each flight condition. Again, you can only select one exponential value for each flight

condition.

9. Return to the regular operating mode by pressing the two

Edit Up Down

keys simultaneously.

If you move to the TRIM menu with the

Edit Up Down

key, the flight condition indicators are

shown in the lower right of the screen, to tell you which is active. You can change the trims

in one flight condition, and they are stored separately and called up with you switch between

them. That’s really cool!

STRM

— Subtrim Settings

The Subtrim window is used to make small adjustments or corrections in the neutral

position of each servo, independent of the trim levers. The recommended procedure is to zero

out both the trims (see

settings

menu) and the subtrims (this menu). Then, one mounts the servo

arms and sets up linkages so that the neutral position of each control surface is as close to where

it should be as possible, with the arm 90° to the pushrod. Finally, small amounts of subtrim are

used to make fine corrections. We recommend that you try to keep all of the subtrim values of

as small as possible. Otherwise, when the subtrims are large values, the servo’s full range of

travel may be restricted.

between -100% and +100%. If you want to reset the value back to zero, press the

Active/Inhibit (Clear) key.

4. Repeat steps 2 and 3 for each channel to be adjusted in turn.

5. Return to the regular operating mode by pressing the two

REV

— Servo Reversing

The servo reverse function may be used when you need to change the direction that a

servo responds to a control stick motion. When you use this function, BE SURE THAT YOUR

CONTROL IS MOVING THE CORRECT DIRECTION. If you are using any preprogrammed
