Had my octane 3 weeks now pulling wheelies changing up gears running in great ,this is a great monster truck IMO , upgraded a few things like servos changed stock ones to savox ,put my own proline wheels and tyres on wheelie bar ,savage suspension conversion kit,in time I'll change the transmitter and reciever ,my only fault with with this car apart from price us the noise it's very loud louder than my baja I've heard in time there will be an exhaust upgrade that will bring sound levels down.......
