Hello i will recieve my redcat mt tommorrow pretty excited. i have been reading through the posts on here, and just wondering about the stock drive gears and the drive cups. Did the Redcat upgrade kit fix these problems or is there still a issue. I seen a lot of Tips here like drill holes in the gear cover to remove heat, or tempering the drive cup. This will be my first gas truck, i have been in nitro for a while, so any input well help. thanks
