Liking this truck alot, been running it on indoor high bite clay. I have the truck working VERY well but I am running into the nose down jumping if I don't hit the jumps perfect every time, it makes it where I am timid to push the truck too hard in certain sections of the track. I am wining and placing well with it but I have to get this sorted. I hate to go stiff on the rear springs because it will upset other areas of the truck that are perfect. I may try the battery mod like alot of people did on the gen1, anyone try that on the .3 yet? This truck does EVERYTHING else so well, I just got to find a "good" fix for its jumping attitude.I am running a 550 can motor in the truck, what does going to a lighter 540 can motor usually do on these trucks as far as balance and jumping etc?
