Well, My benders run real strong and I've been averaging around 120 miles per tank at 55 mph avg. speed. The power they produce, IMO, make the Viper where it's suppose to be. It's alot more fun and competitive when racing. The problem I'm having is Getting the traction to the ground!!!! Stock track (I know replace) with 192 studs. Even with the transfer rods set for all transfer, it just spins like a phazer on ice...LOL, but irritating.

I love my Viper and am not replacing it for another 2-3 years or if an influx og money comes in, whatever comes first.
