Hi John,
I am useing 2" Maxx produces wheel. Plastic 5 spoke hub with a black foam tire.
Very nice wheels! You will need a prop adapter. Check the specs. on the motor for the shaft size. I think it a 3.2mm adapter. I use odorless Zap Brand because thats what is carried in NY.

Before you start building check out the new "Tips & Tricks" section I have added to my site.
I have a short video on how to fold the foam fuse sections correctly.
So your finished plane will look better and your kit will build easier!

Thanks,
Mike Glass
