Question
5mm shaft prop saver - where can I get one?

I would like to get a prop saver adapter for a 5mm shaft. I can't find any. Does anyone know of a source?

About to give up...

Rob, www.headsuprc.com has them for less than 4.00. Go to adapters pg.2 on their website. 2.00 shipping no matter what you buy. FWIW. art

Hi Art. Thanks for the reply. What am I missing? This is one of my main sources of rc stuff, but I don't see a prop saver for a 5mm shaft. The largest Jeff carries is a 3.17mm

After a quick search, I didn't find any on Google either. Usually motors with 5mm shafts are 1+ horsepower, so a prop saver wouldn't be safe to use for that application.

All I found was this thread:

Good luck, Dave

Yep, I am in the same predicament. The motor is just your standard parkflyer motor, but with the 3-point adapter needed to mount the prop at the "correct" end for my application, the shaft ends up being 5mm.

It sounds like the wing-nut idea might work, but I wish I could find a regular one.

Yep, but that is not a prop saver adapter. It is your standard collet.

5mm shaft should be on a motor that can put out nearly 700 watts, which, if I'm right, would rip any type of rubber band/rubber o-ring to shreds upon powerup, sending your prop through airspace, possibly casuing harm to you, or others.

Haven't found a prop saver that big yet.

I think Bombay just wants one for his 150-200 watt motor with a 5mm radial mount adapter.

Interesting, my motor with a 5mm shaft is only 250 watts.

Try max 150 watts. Right, it is a 3-point or radial mount adapter. It is for a 2830-09 motor...850kv. The manufacturer of the motor (so I am told) does not recommend reversing the shaft on this particular motor. Anyway, I went ahead and ordered a few extra radial adapters as a sub for the prop saver, but I would like to find a source for the savers in 5mm.

just get this one and bore it to 5mm or take it to a machine shop and ask them to do it.. most will drill it out for nothing...

Ahh, much smaller than the 5mm shaft made it out to be.
