In the RC crawler community we use weights in the tires, star shaped cut foams and beadlock wheels to gain traction. even when racing RC cars we use tires that are glued to the rims to keep them attached. some crawlers even use memory foam in their tires. all of these do not use air pressure instead they have holes drilled in the rims to relieve it. In my craler I have narrowed foams in beadlock wheels. Never mind stairs, it will crawl up my couch and wont stop untill it looses traction going straight up the wall behind it. to keep the wheels from getting flat spots we store them sitting on their chassis with the wheels off of the ground.

It will more likely give opportunity to "unrim" the wheel assembly. But I agree that ATV use low pressure balloon tire and that it give them some grip and suspension, and they are filled with foam to avoid them to "unrim" with so low air pressure, as the foam help keeping the shape of the tire. For the traction, up here in Quebec we have lot of snow right now. The tire dig-in the snow very well to go reach a hard buttom to get traction to. Of course it happend that there is to much snow and the Recon stop progressing even if the 6 wheels are spinning, but evey time it happened, just going in reverse got it moving back. A litle bit of spinning is very good to have him unstuck. We have to remeber the scale effect, the Recon pass in snow up to six inches, wich represent 3 feets up to scale 1/6, I think I can be please with that.

I emptied the tyres flat in my Daimler-in-progress, hoping there'll be more traction, better suspension to shocks and because I have seen all large RC buggies and monster tracks' wheels . they contain no more than foam inside the tyres. Still looking gorgeous though. I love improvised metalworks. With very minor adaptions or none, - or with flexible judges- you could apply for a designation number and pass it as a Greyhound. It's got these same sloping fenders.

I have verify the wheel themself without the buggy, but it was cheaper to buy 3 complete items than 6 replacement part, its how the world work these days. The wheels are nine inches diameter. 2- The wheels came on hub that are like 2 dish bolted together, with bearings at the bore. there is as you see on picture "Recon4" four bolts in the center to hold the two side together. Inside the wheels there is an air tube. --~--~---------~--~----~------------~-------~--~----~ You are currently subscribed to the "R/C Tank Combat" group.
