Hey Dean, explain that to me. I bought the JBS Super V and it came with 1:36 gears. We only ran it a few times before sending it in for a face lift, but full of fuel it is an absolute pig on acceleration. My guess is it will pick up with a lighter fuel load, but is the top end increase really enough to overcome the total lack of acceleration in race conditions? Hard to believe but I guess it must since so many are running that combination.
