In FUNC.LIST list, highlight REV. SW. Press the
Selector to access the reverse switch menu. Highlight
the desired channel then press the Selector to reverse
the selected channel’s direction. Check the direction of all
servos and reverse as necessary. Press the LIST button to
return to the Function Mode screen.
In FUNC.LIST rotate the Selector until Sub-Trim is
highlighted. Press the Selector to access the Sub-Trim
menu. Highlight the desired channel, then press the
Selector to change the sub-trim value of that channel. Set
the sub-trim for all functions in the neutral position. (see
flap note below). Press the LIST button to return to the
Function Mode screen.
Note: Typical flap geometry requires the sub-trim
be significantly offset to provide adequate down flap
throw. This issue exists because flaps typically have
a large travel down (80 to 90 degrees) but very little
travel up (less than 15 degrees). To achieve proper
flap travel, it is necessary that the right flap sub-trim
be set at 225 down and the left flap sub-trim be set
at 225 up as a starting point. Then, when attaching
the flap servo arms, be sure the spoiler stick is in
the up position and camber lever is in the middle
position. Install the flap servo horns so they are
angled approximately 30% toward the trailing edge,
then adjust the flap linkage so the flaps are level.
