I have an 88 inch 182 that only has one servo for flaps and it's just done/operated with linkage rods, no mystery. If it is two servos it's just a mater of going in and reversing the one going up, again, no big mystery. Very easwy to do with the 9-C.
I find that people that have only operated/assembled ARFs and never built a kit plane don't understand a lot of the mechanical set ups often used in kits. Not a put down, just a fact. My Cessna is an old PICA kit built plane and I'm sure a lot of the set up would be a mystery to anyone that has just gotten into the hobby in the last decade or so.
