The orange were known for causing esc’s to go up in flames. Really easy to plug in backwards- not fully but enough to make contact. The green was the updated version that was just a little tougher to zap, plus it has a ceramic ball to increase the pressure between the plates.

Fine M3 threads are .035 pitch, and I don't think there are any heli coil kits out there for that. You could try a course .05 coil, but the body of the motor doesn't have much to grab on to, so not sure if that is a viable option, but such things are available. If the fine threads are stripped in th...

M3 Helicoil. Install the coil with Locktite.

....We have a forum member that can turn a Trinity into a LeMan's (and looked really good). Ever considered running a counterfeit LeMans? Or even just the can from another motor?

Wood screws. No joke. I was poor and known to strip a lot of motor mounting holes.

I'd try a thread insert , they are designed to be used as metal thread inserts for plastic parts ,I have some in M3 , you stick them onto the tip of a soldering iron and push them into a plastic hole meeting them into place , they are knurled on the out side to grip , I think if you drilled out the ...

Helicoil is best. It's a tiny repair though so care is needed.

Alternately, do as you mentioned, run a screw from inside and turn it into a stud/nut arrangement. A single nut is fine, along with a washer.

The tough thing about a stud screw from the inside is that there won't be any can threads for that screw to bite into, so bonding is strictly by adhesive. Tightening and loosening a nut on the outside has potential to break the adhesive bond loose and make it difficult to tighten or loosen the exter...

M3X0.5 is the common size. I have that exact kit. After slightly modifying the tool, it works fine. Thanks! Could you elaborate on the tool modification? I haven’t done a helicoil before but have seen a couple videos so have a basic understanding at this point. It wasn't much. The tip of the tool w...

M3X0.5 is the common size. Not sure why I had .35 pitch in my head, but as usual, JC is right on it and dead on. With M3 .5, a rivnut could be an option. With such small hardware, I wouldn't think an actual rivnut tool would be required, as a jerry-rigged pulling / prying device shouldn't be diffic...

I have repaired many Le Mans motors with 3m knurled inserts from Ebay...works perfect....make sure u drill properly and I used a vice to press them in

With M3 .5, a rivnut could be an option. With such small hardware, I wouldn't think an actual rivnut tool would be required, as a jerry-rigged pulling / prying device shouldn't be difficult to come up with. i didn't know these existed. very interesting! The M3 ones I've found seem quite long (9mm) ...
