How to Reverse a Servo - RC Model Geeks

Here we show you how to reverse a servo electrically, without the need for servo reversing on the transmitter.

Thanks! Especially for mentioning that the procedure is the same for both analog & digital servos.

Awesome, If you F it up it's on you,...Ahahahaha

Tell your mate to be quiet when he is filming 😁

That,s good yet another good tip .thanks.

I have done this many times in the past when transmitters were not so versatile but these days I would use 2 channels and mix them. The problem that you noted whereby you cannot get the servo arm exactly at 90 degrees when the servo is centered cannot be resolved when using a Y lead unless you are very lucky.
Back in the "Old Days" Futaba servos had an odd number of splines on the output shaft and servo horns and by moving the X shaped horn around you could get much finer control of the centered position because each arm was at a slightly different angle due to the number of splines. The 4 arms on the X shaped horn were numbered so that they could be differentiated.
I suspect that not many people knew this even then and put up with non centered output arms. These days we just dial in a bit of sub trim.

I forgot to mention in the video that indeed i have found even the cheapo servos do indeed have offset splines on the output arms. As you say not many people know or notice it ;o)

Try this on a micro 90S where there are no 3 wires.@@Rcmodelgeeks

[@FPVDiverBomber]

thanks , just what I needed... going to make a fpv head turning cam that goes with my steering,,,,and I need the servo reversed... Perfect

[@luisgalvez9868]

thanks , just what I needed.

[@DLM517]

Try this on a micro servo as the internal portion is one unit!

[@RedBaron1619]

Great video ... thanks

[@scottthompson2481]

This is the far better way of doing it , its done , its not going to get un-reversed or changed , the correct way to do the job ......

[@Rcmodelgeeks]

Cheers Scott. Watch this space for the reasons behind it ;o)

[@RcBuddy]

Thanks and nice tip on how they do it ;o)

[@Rcmodelgeeks]

Thanks FG ;o)

[@samwickham4236]

Tricopters run a servo off the fc board from the giro, so this is much more use full. cheers.

[@Rcmodelgeeks]

Glad you found it useful ;o)

[@kevinbosworth3]

you still about on here

[@reefer2917]

Hmmmm, spare channel and program, would take me 30seconds? maybe 1 minute, change 1 channel from 100 weight to -100, on my 9xr pro with flysky module, I know what I would do, yours is another Most complicated way of doing the same thing, but hey whatever floats your boat! :-D love your vids, and with the old Tx's that's the way we would have done it.

[@prep0wer]

Also preventing interference, current loss, you won't lose function of the 2 servo's the same time usw.

[@Rcmodelgeeks]

There is a reason for doing it this way and all will be revealed in a later video ;o)

[@prep0wer]

Digifleet?

[@jeffreywayne4012]

great love it ....you both are fantastic ....love the phone ....sound ...colin.....thanks for making me laugh....cheers. great what rob said at .the end....i bet there will be some who fuck it up....lol .jeff...

[@Rcmodelgeeks]

Cheers Jeff! Cheques in the post ;o)

Is there a way to determine the correct wires to switch whenever they are all the same color? Also, I've got an emax servo and there are 3 wires attached to the motor. . . 2 are going to the poles(as shown in your vid) and 1 is soldered to the can. I'm assuming reverse the two that are attached to the poles?
