AIL-2 allows FLAPERON and AIL-DIFF with a 5-channel receiver. AIL-2 only tells the
radio that you are using CH5 and CH6 (FLAPERON), CH5
and CH7 (AIL-DIFF),
not CH6 or CH7, as the second servo in FLAPERON or AIL-DIFF. You still must activate
and set up the FLAPERON/AIL-DIFF function.
Note that selecting CH5&6 or CH5&7 does NOT free up CH6 or CH7 to be used for other functions when using a receiver
with more than 5 channels. Both 5 and 6 (FLAPERON)/7 (AIL-DIFF) are dedicated to the FLAPERON or AIL-DIFF programming.
[This is beneficial with four aileron servos that need to have their end points or sub-trims set separately. CH1, CH5 and
CH6 are already fully set up to operate as ailerons. Mix CH7 or CH8 (the second aileron servo on the other side) into
ailerons to function properly.]
