Du-Bro Super Lite 1 3/4" Diameter R/C Airplane Wheels
I used one of these wheels on a SkyHunter FPV as a front steerable nose wheel and It worked very well.
I like the fact that it's so light and has good traction.
lightweight, and durable these dubro super lite wheels are perfect for keeping flying weight down to a minimum, and are plenty tough enough to withstand the roughest landings.
