Art, I haven't used that specific servo, but I've used other waypoints and really like them. I'd send Bob over at Allerc an email (contact info is on the site) and ask him about it.

It's funny that the ads page says 110 deg. but when you click on the link there for data they list a different degree for that servo [W-150MGR].

It doesn't look like they are proportional reading the data sheet. Like most retract servos they start moving and don't stop until they reach the end of the travel. In this case it looks like the servo travels 125 degrees each time it is instructed to move regardless of the channel on your receiver it is plugged into.

W-150MGR 125-Deg Retract, Metal-Gear
Weight : 16.2g/0.59oz
Torque : 4.8V / 3.9kg-cm / 52oz-in
Travel Angle 125 degrees
Speed : 4.8V/0.19sec/60?
Size(mm) : 26x13x26
Size(inch) : 1.16x0.51x1.02
Motor type : 3-Pole Ferrite
Gear type : Metal

Mighty fast for a retract servo, my Hitec servo takes 4 secs to run 180*.... so it is much more scale movement than .4 secs for whole travel. SLAM BOOM BANG, as retracts slam in their slots..

Have one in my Hyp 51, works fine, as Ceeray says, fast, And you cannot electronically slow it down.

Thanks all. Sounds like it is non-proportional... which is a good thing for a retract servo.

It would be neat to find a way to make it proportional. At 52 in/oz of torque that would be one monster of a lightweight servo with metal gears.

Was working with one in my Acme Beech C-45 last night. Definately non-proportional.

Hyperion also makes a servo rate adjuster, but it cannot be used with a true (non-proportional) retract servo. It's actually two rate adjusters in one: two inputs, two outputs, one PCB and adjustment micropot.

I used one of these in my ultrafly P-51. I didn't like it. I mean it was a nice servo, but it was made to go endpoint to endpoint. I can adjust the endpoint on all my other servos. But this servo can not be adjusted.

If you want any of these, I have 2 Waypoint W-150mrs retract servos that I am trying to sell. One is NIB. The other is slightly used. I also have a package of extra arms for each one. I also have 2 dionysus Design servo rate reducers that I am trying to sell. Pm me if you are interested in any of these.
