RE: Speed Freaks Wanted- Over 150 Members already !
The Viper is good but I prefer the Lanier Predator II. A little wider stance on the gear and the wheels and axles on the Viper tend to come loose right when you need them which is every flight. Those little special screws that hold the wheels on ( Viper gear ) are hard to find or replace. This is just my personal experience. I just do what works best for me. Everyone is different. Muffler? It's hard to beat an Ultrathrust but a mousse can will work well if you know how to make one.
