thachowman this is in response to your post in the other thread. thought it would be better served here.
you may want to get a little stronger servo?
maybe look into a better chassis? Like a Penguin R/C P3500 series.
or if you have a stock chassis you can use it and cut about a 5-7mm slot on either side of the chassis where the rear pod meets the main chassis area.
what wheelbase are you running? the shorter 140mm wb usually offers better steering response. and have not heard of to many guys that like the GPM X-shocks if that's what your running? most seem to like the stock suspension set up better.
good luck with your racing! give em hell!
