Optima Limiter Gear Nut
Optima Limiter Gear Nut
I am missing the reverse thread nut that fastens the Optima limiter gear. Does anyone have a good online resource for finding these type of nuts? Am having a hard time finding a replacement. Thanks.

Re: Optima Limiter Gear Nut
I think Your best shot would be a hardware store or an old model aviation shop that carries Graupner or Robbe spares.
You use a M2,5 polyamid nut and force it on.
German ebay has a set of M3 links and rechts mutter, one of each, but this is not lock nuts.
Or You could buy a M3 links gewinde tap (reversed thread) at the german ebay.
I´ll check my local hardware store monday and see if they stock any reverse threaded lock nuts.

Re: Optima Limiter Gear Nut
Don't force a metal nut on there because the shaft will break
If you can't find anything, the best thing to do would be to use a nylon nut (losi 4-40). The nylon ones from kyosho are too soft (and small) and may not hold. The PRM versions may work as well.

@DennisM, @Highwayracer
Thanks for the ideas guys. I hadn't considered a nylon nut. Can't seem to find the reverse thread M3 nut anywhere, even specialty shops.

Re: Optima Limiter Gear Nut
McMaster Carr has some left hand nuts

You can alway take a normal nut and deform it just a bit to make it a lock nut.

Re: Optima Limiter Gear Nut

Re: Optima Limiter Gear Nut
One thing I forgot to mention is that the RPM nylon nuts aren't threaded. They can be used for 4-40 or 3mm in either standard or reverse thread ![Very Happy :D](./images/smilies/icon_biggrin.gif)

Re: Optima Limiter Gear Nut
I have an ot-74 limiter gear, and its fixed with a philips head screw. Is this not the same gear set? Were there different productions of the same part?

Re: Optima Limiter Gear Nut
There were a few variations of that shaft and gear

Re: Optima Limiter Gear Nut
That doesn't sound right; there should be a threaded shaft protruding through the limiter gear, with the gear attaching with a gold-colored reverse-threaded nut. The original Optima gear (not the Turbo's OT-74 Limiter Gear assembly) is just a sold single part with the gear fused to the shaft, so no nut or screw. Also note that there are 2 kinds of OT-74; some had a thick, beefy spring while the other had 3 or 4 little spring-washers. They did the same thing but I've heard the beefy spring one was the better one.
More discussion on this gear setup is here:

I've never owned the OT-74 with the spring-washers, though...only the thick spring kind.

Ahh, go figure, that's the variety I never owned, and the pic I found of it only shows the side view. ![Razz :P](./images/smilies/icon_razz.gif)
