what is the best running temp . 2nd should i be able to hear it shift in to 2nd gear .i had a t-maxx and i could hear it shift and it would make the tale end sit down. and i know this beast should do that and more. this is what i would like for this old boy to do . i would like for it to pick the tires up a little when it hits 2nd gear. it does not sound like it is stuck in first .as far as a high rev. i'm new to the r/c hobbie truck, as far as the tunning gose. but i have 15 years as maint-tech. so any help would be greatful.
