Found this at Mennards a couple weeks ago for less than $8. Fits my 500x5 wheels perfectly and makes moving the fuselage around the shop a breeze. See no reason they won't fit the SkyBolt 600x6 tires. I don't think they are strong enough to take the engine weight but you have 2-3 years of fuselage moving before you ever mount the engine.
