Flap servo problems
Hey,
Just assembling my first plane with proper flaps and am having a bit of travel. The flaps require two servos, one in each side of the wing, joined together by a y-lead. When i lower the flaps, they go like ailerons, one up, one down. I can't really rotate the servo around 180 because of the design.
What happens if, on one servo, i change the positive and negative wires around on the servo lead? Does is work like a normal brushed motor, ie. it will rotate the opposite way??
Any help will be great!!

You could also use a standard servo on one side and a "reverse" version on the other like Hangar 9 does in their F-22 trainer. They use JSP20050 AND JSP20050R servos.

RE: Flap servo problems
Different brands of servos are said by some to rotate in different directions. Anybody know the differences for sure?
If you're using the same brand throughout, the usual practice is to have the two aileron servo arms both point out or both point in, and to have the servo arms on the two flap servos both point either right or point left.
Changing one of the flap servo arms to point the other way should only be as hard as moving the location of the flap horn on one flap. And pulling the servo arm off and putting it back 180degrees.
