Help! Large RC wheel suggestions

[JozMk.II]

Hi,

I’m scratch-building a semi-scale electric 10-ft-wingspan B-25. When it’s finished, it’ll weigh around 30lbs. I was wondering if anyone has any suggestions for wheels? I was thinking of using a pair of Du-Bro 7” diameters for the mains, but they cost close to $50 each! Any and all suggestions are appreciated!

Anything 7" diameter with a plastic hub should work. Lots of kids toys have such, and maybe $5 usd at a thrift store on a scooter or training wheels. Big problem will be the hub adapter because they are 3/8 dia holes or bigger.. making them look vintage WW2 however......
