I'm also interested in this thread and looking for some help with mine. I love it but have 2 major problems with it and both are to do with the torque.
I keep twisting drive shafts and Rounding off the hex wheel centres. I've swapped the shafts to T-Maxx ones that have so far, lasted longer. I also have to put the dual rate down to 46% just to save the wheels. It's now back in the man cave awaiting new wheels anyway. When it runs, it's great fun though.
