I posted this on the Electric Training section as well.

OK, I have 2 motors that I want to replace a bent shaft on, #1 Rimfire .32, #2 Eflite Bl25.

Both motors have a hex key set screw that is not a 1.5mm (too small) and it is not 2mm (too large). I have searched for a 1.75mm hex key or something in between 1.5 and 2.0mm without success.

Is this some special size that is only available to the manufacturers or am I missing something here?

I have searched some of the other threads on the internet and it seems the Heli guys have the same problem with paddle screws.

I have already stripped out the socket on the Eflite by trying to use a 1.5mm hex, I did not use the ball end either because of the sloppy fit.

I spoke with Horizon about this to see if I could send in the motor and have them replace the shaft, they informed me that tthey did not do repairs on motors and that basically it is a disposable item.

Anyone know whats going on or is that basically it, disposable?

Should be a 1/16 then. .0625

The quality of some hex keys leaves a bit to be desired. That, plus locktite on the setscrews is often nothing but trouble.

oh for sure on the quality.
