I purchased this truck from someone at the track that was apparently fed up with it and I was never really a fan of monster trucks. I bought it and man I love this thing its incredibly fun on and off the track. A few problems though it has the Picco .21 in it and apparently it had too much power so he made it so it only has 2nd gear..... How do i change it back is it like a revo? and what size wrench? And has anybody had problems with the motor mount for the Picco? I have gutted out 2 already???
