!/8 couplers are bigger than 3mm. Jeff Wohlt is making mine. I would suggest you order one from him.

The second run what nice! Did you move the battery forward to gain more balance?

I adjusted the strut to have a little down in it.

For those of you who want to run this motor I got my coupler from Jeff Wolht and it fits perfectly. I'll get some video shortly of what this motor can do.
