i am just starting to fit the retracts into my century airwolf/raptor 50
running three jr 591 std servos into a jr matchbox ! jr pcm10x tx
iwas thinking about getting a servo slow lead just to slow down the servos a bit for a bit more scale speed any body got any comments good or bad ? or any help or me ?

if you are using the futaba 9c it has a feature just for that. the 9z does too. unfortunately JR, my favorite brand mind you,. does not believe heli pilots have the need for such a feature. boy are they wrong

drive a rotary, fly a rotorcraft

If I remmeber correctly, using any type of servo slow device will have no effect at all on a retract servo.
These are switched in operation and not proportional. The speed is therefore fixed by the gear ratioin the servo. You can always use the servo slow with a proportional servo, as it is intended to buffer the servo pulse, which then has the effect of slowing the outputs speed. You may of coarse have to increase the servo travel at the same time.

Scale speed for retracts

I did try retract servo but i had no luck with them right pain in the butt!
so i am sticking with proportional servos with a matchbox it works well i just need to slow them down a bit !

How do you slow a servo using a 9C ? I thought it was only the 9Z that had that feature.

Thanks.

Same question here. I fly with a 9C and there is no function I can find to slow any servo down. All ears here.

hmmm, i may be wrong but i am sure i have heard of guys doing that with the 9C as well. maybe it is only the airplane version. i am predominantly a JR man with all my helis. futaba only flies my airplanes. no special reason as to why that is though.

If you assign the retract Servo to one of the side levers on the 9C you can control the speed of the servo.. I've got mine assigned to VR - B

ssssssslow retracts..

I have posted this before because I am such a fan of this product. I installed a "go slow" in my 30 size 222 for the retracts and it works great. I used two S148 servos I had lying around and I can adjust the up and down of the servos from 2-10 seconds.

Check it out

Just an option that I though you might like to know about.

So it's a manual delay function? Not too slick an idea IMHO. Retract speed should pretty much be the same every time and a timing ckt operated by a binary switch is the only way to go. The slider approach just sounds like a Rube Goldberg approach to me.

Only the 9C Super has the servo travel delay functionality.

You can get pretty much the same speed every time,, not exact like a purpose built unit obviously but you still retain the full speed of the servo if required

Let me give you this scenario

In the hover 10ft up , retracts up ,engine cuts out, with a slow retract you will not get the gear down in time ,Lands on the bottom of the fuse = damage every time from scratches to splits

Same scenario but retract assigned to the slider gear will come down rapid and will take the brunt of the landing = minimal damage if any

Assumes a lot about your reaction time. I'm sure yours is way better than mine,

Not really...... Its just that a finger is resting beside the slider and i dont have to worry about hitting the right switch
