Zippkits mini sprint

No, .1mm is too far out for a coupling.

[dahodevil]

Native Paul. You have been a tremendous help for me. I really appreciate all the info you have given me.
If I can't find the right Coupling I may be buying a lathe and making it myself.
Again, thank you

Talk to Jeff Wohlt over at rcraceboat.com he might be able to make you the coupling.

[NativePaul]

I don't want to stop you buying a lathe if you want one, as now I am not at my dad's shop so much I want one myself, but I expect Jeff Wohlt would make you a 4mm-.062 coupling, have you bought the motor yet? If not you may also want to consider the HET RC EDF3W which is a clone of the Mega 16/15/3 that I use and available at about the same price point as Leopard motors and uses a more common 1/8" shaft, so you might find it easier finding a commercial coupling to suit.

[dahodevil]

Yeah, I already have the motor. I didn't check the shaft size before I ordered it.
