RE: Flap switch sanwa vg600
On the VG 600 that flap switch is a three position switch (Don,t remember ch five or six) that actuates independant flaps to three positions (usually up, half and full down). The airplane must have dedicated flaps not flaperons and they could be actuated by one or two servos on a Y cord. This Tx will not support flaperons.
Since this is the beginers forum, flaps or flaperons on the majority of trainers is redundant and even likely to lengthen the learning curve pointlessly.
Both channel five or six could also be used for other things like retract gear or bomb release whatever.
