REV-XP/XS Chassis: Perf. Trail 120-129 Inch Models
I just dropped in a few parts to see what turns out I pit the pink/green spring 19.6 grams on 414 ramps stock qrs. I have a few different ramps 410/419 ect also some qrs springs from Goodwin kits. Basically I've bought 2 kits and wasn't happy with either one and went back to stock.
