Does anyone make an adapter to use nitro clutch bells on the electric motors? I would just buy a mod1 pinion except this is a two speed clutch bell that I have for an old pirate 10.
Not that I know of. You might be able to modify it, but will be toough as they are made of hardened steel most of the time. I would just get the appropriate pinion.
Unfortunately, there is no appropriate pinion. I think I can make it work with an airplane prop adapter. A little bit ugly, but it has worked in the past.
If you have access to a lathe (this is what it will take), you could turn an adapter to fit into the recesses on the clutch bell and use some jb weld to fix it in there. I did something similar when I first started on brushless, but didn't use it for long, since my order came in faster than I thought it would.
I think I used aluminum bronze to make the part. It's easy to work with and resists abrasion pretty well.
