Had the ST2 out this weekend, after approx 25 minutes of run time, the truck came to a halt. Both first and second gear had damage to a quarter of the gear… it had melted. I'm pretty sure the engine wasn't overheating, though I didn't take any readings!!!
I was running the truck on some loose gravel, could a stone of caught up in the gear causing it to snap and melt to the clutch bell? Or have I got it set up wrong - have changed both gears now and runs fine off the floor!
Also, where could I get both gears made from Steel or Ali - from a company that'll ship to the UK as I can't seem to find them?

Cheers
