What are the chances that prop adapters for outrunner motors are interchangeable? I have an Omega 130G and the prop adapter appears to have a slight wobble machined in, and the supplied prop nut is slightly oversize and jams on the threads. I was wondering if I picked up a prop adapter from Tower for a 35mm Rimfire if the bolt pattern would be the same.

I welcome any feedback, in the meanwhile I ordered the RImfire adapter to see if it fits. I will report the result back here. Thanks.

Depends on what you mean by "prop adapter".

There are prop adapters that slide onto the motor shaft, and are either the collet type, or have a set screw to clamp onto the shaft. With that type of prop adapter, you just need to be sure the the adapter is made for your motor's shaft size.

If you're talking about a prop adapter that bolts onto the can of an outrunner, then you probably need the part made specifically for your motor.

The latter. The adapter bolts to the front of the motor with 4 allen screws. The good news is I contacted 3D Hobby and they are sending a new prop adapter. Thanks 3D Hobby Shop!

FWIW the 35mm Rimfire adapter does not fit the Omega 130G. The hole spacing is different.
