I was able to get replacement gears from ML Toys and Mike there has been great to work with. Last night I put everything back together and my son ran the truck for 10-15 minuets under 12v and no issues. I put the 2nd battery in for 24v and within 15 minuets he had already started to strip the 3rd & 4th gears. Is there another option out there for stronger/aluminum gears? My son weights around 65lbs and it seam to only strip out on the drivers side. I wouldn't think the weight is the issue. The axle was hot when I broke the truck down to remove the motor. I also checked to make sure the axle was not bent. I imagine if I try to get something made local the cost will be ridiculous. Any help would be appreciated.
