Had this sitting around for a while and as my nephews had a Twin Detonator and BF Extreme for Christmas we decided to give this to my son. Built it with him today before school starts back tomorrow. This is fitted with ballraces and cool looking Mtroniks Blue Heat 19x2t motors. Goes very well but need to change the pinions to 20t items (on order) and maybe fit an ESC as we stuck to the stock controller.
