Yep, for flaps or when you need them to both move same direction, check for movement, then install oriented right way. Example-servo horn pointed to left on both sides. Might not look as good as aileron installation, but being hidden in wing or covered with hatches, it won't be noticeable at all. Or, use a single servo to operate both spoilers, solves the orientation and saves weight as well.
The Elite has flaps not spoilers and it has them on two separate wings. Though I suppose someone with a good bit of building skills could ginny something up I can't see where it would be easy. Especially since the Elite as far as I know, only came in an ARF.
Harrieet, while that may sound cool and look neat on the bench, in flight it serves no purpose and you really want to get the flaps up quickly right before or when you touch the ground, esp if you're landing in tall grass.
