Well I sold my Savy yesterday and now have on order a Matrix arena tr. I ordered this as a roller, it is new minus electrics and motor. So I ordered some high torque servos for throttle and steering, a Axial .28 spec one, OFNA tuned pipe JP2 polished, and a Spektrum Tx/Rx. All this was only $580, is there any thing else I might want to get for this? Are there weak or bad areas on this truggy? Thanks for any help.
