We had some nice weather today and I was able to get out for some testing of the pistons in my Durango DESC410r short course truck. This is a large 1/8 track with whoop sections that I could never keep the truck stable before. I had driven losi's that did not have to let up on these sections and this was where they would make up ground on me. I started out at 25wt and the truck felt pretty good and I could go through the whoops with some better stability. So, next battery I bumped to 32 1/2 wt and I could fly through the whoops. Only problem it was too much pack for some of the other flat landers. So, next test day will be 27 1/2 and 30 to find the sweet spot. I plan on purchasing these for my DNX408 next.
