2 things i noticed within the second tank of having it in 2 wheel drive.. first it handled worse then a 2wheel drive nitro stadium truck,it just as heavy and has 1/2 the stearing.. second(your gona love this) i had destroyed a BRAND NEW REAR DIFF.. i had replaced both front and rear diffs from locking up the brakes at full throttle on pavement, durring the process i forgot to put the small set screw thru the front drive shaft.. i sead ahh.. ill just finish this tank out on the grass.. wishfull thinking!!.. this rig was engineered and designed for 4wheeldrive, so put it back together..
