Slim Jim servo instructions & Single Channel receivers
Hello, I am new to the forum and not sure how it works! I am trying to get my model boats going again after a 50+ years break. I am looking for Slim Jim servo instructions as I can not remember how to connect them up (Does anyone have a copy please). Also I have vairious single channel Transmitters with no Receivers (Does anyone know of a source of crystal controled relay 27mhz receivers). I hope this message works and look forward to any replies, Malc.

Hi Malc,
Welcome to our retro Valhalla.
Which version of the slim Jim instructions are you looking for.
There were at least 2, possibly 3 versions.
Any particular brand of 27mhz s/c rx you are looking for?
Cheers,
Shaun.

Re: Slim Jim servo instructions & Single Channel receivers
Hi Shaun, Thank you for your reply, I am still sorting out how the forum works, but getting there slowly! I have several Slim Jim servos but no idea which models, some have 3, 4 or 6 wires to connect (does that give a clue)? I also would like to use my Gem and RCS transmitters but am not worried which receivers to use. Crystal controled would be best so I can sail with other club members and a total of 4 Rx`s would be great so I don`t have to keep moving from boat to boat. By the way I am quite happy to pay any costs involved if you can help, Malc.

I'll have a look and see if I have any spare relay rx's in my bits box.

Re: Slim Jim servo instructions & Single Channel receivers
Slim jims were odd because you pressed once for left , twice for right. The opposite of all escapements such as Elmic.
There was a version of the slim Jim for relayless rx's

Resolved simply by moving the output crank (at either the motor or rudder) by 180 degrees on the shaft, Nest'ce'pas ?

Re: Slim Jim servo instructions & Single Channel receivers
Yes ,they chose to be different.
The slim Jim was intended to be installed like a traditional escapement using a torque rod (see diagram,) not via a pushrod. I seem to remember also that the output shaft had a flat on it keying the arm in one position. Moving the out put arm wouldn't change the direction of rotation. In a boat however you could easily change direction with a push rod. A few Japanese motorised actuators also used this key sequence.In fact one set up was. 1st press left, 2nd right, 3rd up, 4th down, 5th throttle change... No quick blip. I set one up to see and glad I didn't try it in the air. Not easy to get the throttle correct. ..

Hi Shaun, Thanks for the diagram, I am sure I can get them working from that. I will keep my fingers crossed regarding the receivers. Best wishes, Malc.

Re: Slim Jim servo instructions & Single Channel receivers
Shaun kindly gave me a Slim Jim to go with my Astral Tx a while back (both made by Modelectric Ltd), so here are some pictures and a scan of the instructions so you can all see what one looks like
And I found a spare label for the Tx on eBay recently, quite a bizarre find
