What kv motor are you running?Ol' fart came through for this Canuck. Awesome motor mount. Had to move the centre diff 4mm back to fit in the massive Leopard 58110 motor. Juuuuust fits now. This thing honks. Test run showed 103kms/hr. Unfortunately blew out the rear tire foam on the third pass...lol...Gotta get some more of those, just in case. Motor and xlx both run at a decent temp. Was running 16t with stock 41t. just ordered an 18T to see what this puppy will do.
