Default Futaba 9c, Can I Slow My Retract Servo Down??

Can the 9c slow a high speed high torque servo down so the wheels don't slam up and down?
thanks Marshy

Default Hitec digital

Hello Marshy,
Another option might be a hitec digital. If you have, or know someone with the programmer, you can slow those servos down with the program.

I think the only servo you can slow down in the Throttle servo.

What kind of retracts are you using? If they are air, you need restrictors in the lines. Just wondering.

Default 5 point curve

Straight up expo I don't think it will do.
It will slow down at the end of one direction but it will be fast as hell at the end of the opposite direction.
I think the answer might be if you try to use one the mixes that have the 5 points in them. Program your gear channel as master and slave and then program the 2 top points close together so that the line between them is as flat as possible. Now do the same for the 2 bottom points. Point number 3 should stay in the middle.
The end result should be that the servo will be slow at the ends and fast in the middle.
But all that is just theory and I don't have a way to verify it until I get back home. :tired:

This should be pretty simple really. Just assign the landing gear to one of the dials or the left or right "trigger" levers and you should have a "manual" control over the servo position. someone correct me if I am wrong but I don't see why you can't do this.

Marshy, can we just be clear that you are using an "ordinary" servo and not a retract servo? Retract servos can not be slowed by any method at all as they are end to end devices, though I have heard that Airtronics do a proportional retract servo which would accept electronic slowing.

An ordinary servo can not be slowed by expo if used on a switch. Switches don't have expo for the simple reason there are no values between +100% and -100% for it to curve! Servo slowing is built in to some top end transmitters, or you can buy an add-on that plugs in between the Rx and servo. In either case you flick a switch which knocks the value from +100% to-100% instantly but the slowing electronics intervene and generate a travel value number sequence 99%, 98%, 97%,,,,,,-98%, -99%,-100%. That way the servo slowly follows the numbers it is being sent.

Without that you could do as flapbreaker suggests and manually move a proportional control at the speed you want though it could lead to problems and take your mind off flying the plane for those few seconds as you try to fiddle the lever.
