I like the HB buggy. I own the RTR 1 and now upgraded to the 4mm shock towers and a rear aluminum brace. I like this buggy a lot even though I mess around with it. It takes a beating and comes back for more. What track are you racing at? I use the stock shock setting and swapped to the kyosho blue medium springs all around. Next I'll be going with 40wt fuel, new diff oils, and test out the droop screws.
