It happened again. But this time instead of just rounding off the wheel hex, it fused inside the wheel. After closer exam, the rim has a crack in it. I think that because of the crack right in the hex socket, the rim expanded so that the wheel hex could turn. It then rounded the rim and melted to the rim. I'm guessing he's going to need a new rim. Can a glued on tire be removed from a rim???

I kind of thought you would have a problem since they spun out before. More than likely they damaged the wheel hexes.
There are a few methods for taking off tires, and none of them are easy. Some people boil them, some people put them in the oven. I think the best method is soaking them in Acetone. You can get it in any hardware store. It's cheap. Put some in a pan, lay the tire in it for a couple of hours, then peel that side out and flip it over for the other side. Keep the pan covered. Acetone evaporates very quickly.
 
I have tried boiling and the oven with mixed results. Needless to say, I won’t be trying either again.

I read an article about the acetone method in XRC recently that Rolex suggested. It looked to be an easy and effective way to do the job.

Be sure to wear rubber gloves and goggles.
 
Sounds good. Just so happens I have some acetone on hand. I had thought of soaking it in something like that but wasn't sure what it would do to the rubber.
I'll give it a shot tomorrow.
Do you think this problem was caused by accelerating too fast and braking too hard??

no the hexes will hold up as long as they are not prviously damaged the usually cause of stripped hexes and rims is the wheel not being held tight against the caster and the wheel hex which allows the two to wiggle around causeing both parts to wear and allow slop which then yes stomping on the gas would ruin an already weakened hex or rim
 
What brand of wheel are you using? If you are using 14mm hexes get aluminum hexes and buy some RPM wheels. RPM wheels are 99% indestructable.
Traxxas wheels will strip out all day long if you have even decent power.
 
Be aware that the acetone dissolves the glue completely. When the foams absorb the acetone/glue mix, then drys, it becomes solid and is pretty much garbage. So, you may be able to save the tires (acetone works really well), but you more than likely will loose the foams.

I recently did 12 old t-maxx tires/rims. Pretty much every single foam was destroyed. Seemed fine until it dried... but there may be a trick to it that I'm unaware of. I let the tires/wheels sit on their side in a pan for 8 hours each side. The tire would basically fall off the rim. So I was able to save 12 tires at least.

Racers Edge has foams that are pretty cheap, $6 for 4 MT foams, but those are for standard MT sized wheels/tires which the revo doesn't have...

I ran aluminum RD logics 14mm hex's when I had my revo, mated to older 2.5 maxx wheels. I never stripped a hex in over a years worth of heavy bashing.
 
I did the boiling water trick a while ago and it worked fine on one wheel but destroyed the other (I spun the hex into my rims too). I still use the plastic hex's and have not had a problem since last fall. What I did was I put two nuts on the outside to keep it from coming lose. I felt that what was causing the spin outs (aka plastic destruction) was the nut keeping the wheel to the axle was coming lose and the torque just devastating the plastic.

Let us know what you decide.
 
I was just about to say this when I saw Olds post, you need to plan on replacing the foam if you go the acetone route. If I were you, I would get your son some RPM rims, because he enjoys bashing a lot and they will be so much tougher than the plastic ones.
 
Unfortunately my sons rc fund has only $18 left in it. So I think for now he will be going with the stock rim, foam insert and plastic wheel hex nuts (which I already have a bag of). I do like the idea of double nutting. I think I'm going to see if I can get some chrome acorns to lock it down. Maybe for his birthday (May 12th) I'll pick him up some parts. He's already started a wish/need list. All he needs now is a job!!
 
I put some lock-tight on the nuts, we had wheels loosen up and sometimes completely come off until we did that.
