Any wheel pant fitting a 3" wheel would work. On mine I installed Cub-style wheels w/ hubs painted to match covering, looks nice too!

My refurbished CG Bucker flies great with the OS 120 AX 2-stroke. Much improved over previous Saito 150. I also shaved about 1/4 lbs from previous covering job, so the glide isn't half-bad for a bipe.
