Need prop help for Super Cub

[dopey190]

Putting together an brushless upgrade and have been doing alot of reading and can not find an answer for the right prop. I put a 480 eflite, I have a couple of 9x6 props. But i think I would have to drill them out for them to fit. Also how in the world does the spinner stay on the shaft lol. Thanks

The spinner back plate gets sandwiched between the prop adapter flange, the prop hub, and the retaining nut/washer. Some spinners have the back plate behind the prop hub and some in front.

The spinner cone either fastens to the backplate with screws or sometimes is retained by a single screw through the middle that screws into a special nut that goes on the end of the prop adapter shaft.

I've got a feeling that I've probably lost you on this but without drawing a diagram it's hard to explain any better.

I take it that you have hot a prop adapter fitted to the motor/shaft?

Not sure about the prop adapter? I have whatever they gave me in the bag that it came with. Figure I would find the right prop and then figure out how to put it on.

So when you put the prop on what are you fitting it onto exactly?

here's a pic:


There are three components in the photo:

1. The motor itself
2. The cross mount (used to mount the motor to the plane but only if motor mounts in front of the mount plate)
3. The prop adapter (fits over motor shaft)

Ok got that now, the million dollar question is which prop?

[JetPlaneFlyer]

A 10x6 for the 910Kv version or a 9x6 for the 1020Kv type should be in the right ballpark assuming you are running a 3s Lipo

Go up and inch if using a 2s lipo
