Has anybody attempted to splice another male plug onto the Tekin wire so you don't have to take the plug out of the rx. I've pulled wires out of 2 plugs already taking them in and out. Wondering if this would work.

I have not done it, but I don't see why it wouldn't work. You would have a plug flapping around though, which you wouldn't want.

Wouldn't it just be easier to put an extension on the esc lead that plugs into the receiver? Then your connection is outside the receiver box and easier to get at. That's how all of our setups are.
