Default Servo reversing

I'm hooking up my flap servos for my Top FLight P-40 and noticed that when I made the servo mounts in the wings, the servos were oposite each other when activated. (One up and one down and vice versa) I was wondering if I could reverse the positive and negative leads on the plug to the reciever instead of reconstructing the servo mounting bay(Flipping the servo over) or buying an expensive servo reverser. Any ideas? Will reversing the poles do the trick?[sm=thumbup.gif][sm=thumbdown.gif]

Thanks

NO it won't do the trick, you'll need to switch the pos and neg on the servo motor and the two outside wires on the pot. A servo reverser is much simpler, or if you can p-mix them if you have a computer radio. An Expert servo reverser is about 8.00

guess I should have done my homework on the reversers. I must have seen something a while back that resembled a reverser that was expensive. Thanks, I'll look into it.

I think the most expensive I've seen is the Electro dynamics 29.95 it is supposed to be self centering and not heat sensitive.

If you're using standard servos you can also try mixing a Futaba and a Hitec unit. They'll turn in oposite directions for a given input. Just 2ΒΆ worth.

Default RE: Servo reversing

I bought the electrodynamics version for two main reasons:

1) It has no adustment dial that can and WILL wear out. The vibrations will also make it move. You center the elevators mechanically and forget about ever adjusting them again.

2) Centering is unaffected between temperatures of 30 and 150 degrees F. So heat changes will have no affect on it.

I'd watch out for $8 reversers if your plane is worth a lot of money. Mine is going in a 25% CAP232 so I want reliability. I've heard of these things failing and I'd bet it's the cheaper ones. You get what you pay for. Just my opinion.
