ran my b44.2 with the schelle chassis and shorty conversion last night for the 1st time,its been a while since i ran mod 4whl and man is this car nimble now,track was a little chopped out and the b44.2 would get tossed around compared to my buddies 22.4 which is an awesome car,i think a little more time it will be more dialed,diffently a good upgrade
