I have fitted a 2 speed gearbox on my Tyrannosaurus (same as a volcano) it runs great but i have noticed that after running it (quite hard[>:]) the wheels keep warping i'm now on my second set, does anyone know of any stronger wheels that would fit and be avalable in the uk.

I'm not sure if they are available easliy, but you might try a set of Traxxas Rear rims and tires for either a Rustler or Stampede, the rims are 2.2, you would need a set of 4 rears. I believe those fit.

Traxxas rustler rear rims will fit, some hpi rims will fit too, they need to be 12mm hex to work.
