Never ran Ofna MBXR2 roller. No electronics or motor. Used Ofna GTLX with .21 motor. No servos or radio equipment. It has been a couple of years since the motor ran but ran the last time I had it out. this is the last of all my nitro stuff. $300 takes all. Looking for off road trades, nice slot car track and cars or let me know what you got. Will consider seperating cars for sale or trade. Buyer pays shipping and I will not ship first on trades.
