Title: Size matters
Post by: old_gunner on May 28, 2020, 03:41:08 pm

I have obtained a Graupner 40Mhz radio and have a problem, the servo plugs seem smaller than my stock of Futaba servo's and ESC's. Any suggestions on where I might be able to source Graupner servo plugs

Futaba servo plugs have a key on the side of the plug to ensure you can't put it into a Futaba receiver the wrong way. However, if you remove this key with a sharp knife I think you will find it fits your Graupner receiver.

Many thanks Barrie, obvious really, my brain has obviously ceased to work logically again thanks for your assistance.

Perhaps worth repeating, once the web has been sliced off, not only will the plug now fit any radio, it will also be possible to plug it in the wrong way round.  The usual standard is to make sure that the black plug wire is nearest the edge of the radio board.

I usually mark on the receiver which way round the plug goes. I used to use sanwa radio which had the positive and negative feed to the servo the opposite way round to futaba gear. The wires to the servo were swapped round at the plug, you just have to remember to swap them back if you are using futaba rx.
