Hi, and welcome to the forum!

First, more information would be good. What's an "electric retract"? A linear actuator?

What load do you need it to move?

What's the power supply?

What's the actual purpose of the thing?

I'm afraid that without more information it's going to be very hard to help much.
Post whatever you can (a bit too much information is better than a bit too little).


Regards,

Torben

The mechanism wanted is already in service - try a 1/4 scale bomber. Many R/C aircraft mags have them listed - and a local R/C shop has one / or can get them for you.
