The ones that they provide the screws for and don't fit any motor mounts are 3MM 50 pitch. Anybody know what the other two, the ones that fit the motor mount holes are?

Might help if you told us what motor and heli you're talking about.

Hmm, well I don't know any of those specifically, but if you're suggesting that all the 400/450 size stuff is the same then I'll throw this out there: For the Align 430 motors the other one is M2.6x6mm. Sorry I don't know the pitch, but would think it's a good bet they're the same as the M3x6mm.

Thanks, that's the only size you can't buy anywhere so that must be what it is.

You might want to double check with helidirect and see if these are the right ones:

They're labeled as 2.5mm but maybe there's a mixup somewhere.

These might work, look like the same thing:

I've got a couple extra pairs (one hex and one philips). I could part with a pair if you want them. I'll send you my fubar'd 430L motor also if you're interested

Nope, 2.5MM won't fit. I found some at a local hardware store. SAE 3-48 is really close but they have to be 2.6. Thanks for your offer but Duratrax uses them on their R/C cars. There are a lot of car oriented hobbys shops here, I'll try them. Interesting side note. Esky uses 3MM for all four motor mount holes.
