hello everyone,



just wondering if there is a need for a reverse servo if you have the room and am able to just turn the servo around (as in my soon to put together arf ) ? i have never heard of these reverse servo's until just lately and was wondering ? been flying quite awhile without them

do they just make things easier during installs? thanks in advance for any info/help.

On a basic 4 channel set up, you don't really need them. When you have independent servos for each control surface plus flaps. They're handy or a reverse switch in the radio or a harness that will reverse the servo.

hi pum,

thanks for the fast response, the reason i was wondering about this is that my plane (hangar 9 B-25) has dual rudder servos and a steering servo (the 1 they say should be a reverse ) all on the same channel connected by a Y harness. so can i get away with using a regular servo for steering and turning it around ? or should i use the reverse ? thanks again.

What exactly do you mean by "turning it around" - if you have the room, and the linkage works out to the other SIDE of the servo arm or wheel, fine - if you mean turning the servo itself around, clockwise is still clockwise, etc.

If it works it's good. Use the other side of the servo horn, reverse the servo on your radio if its advanced enough, buy a reversed servo or you can buy Y harnesses where one lead is reversed. That's what I've used on my applications. Part of the hobby is creativity. As long as its safe, its all good.

I haven't had any experience with the B-25 to be much more specific. Its very important to get it right on that aircraft due to it being a twin engine. It you loose an engine in flight you're doomed without rudder to compensate with.

thank you both,

yes i should have worded it differenlty, i meant use the other side of the servo wheel/arm . now that i have some input i might just go with the reversing Y connector and keep it simple. i havent started this bird yet but have been reading and rereading the instructions before i start.

im very anxious to get going on this plane ive heard alot of good things about it. agin thanks.

P.S. im going to make this bird into an electric version

In the old days (Before reversing switches) We would open up the servo and reverse the motor and potentiometer wires. or buy a reverse servo. now the y harness with the reversing built in is the way to go unless you have a free channel to mix the rudder to.

You could also just use a different make of servo: Hitec rotates opposite to Futaba for example and not worry about a reversing set-up.

Or programmable digital servos can be reversed with the associated programmer, (I think) Have not had the occasion to try it yet.
