i have the bushnell radar gun, i wouldnt say its crappy, it actually very accurate. i have a handheld gps and put that on it, it tells you average mph, highest mph and many other things. 31mph on a single speed is very fast, now way you got 46mph. i have 2 speed hpi rs4 on road and it just reaches the 50 mph mark, the traxxas jato just reaches the 50mph mark. Maybe you have it set for kph or something. Not trying to start trouble but for a 1/10th radio controlled anything to reach 45-50mph is a feat in itself no matter what %nitro your running and how well tuned the engine is. I know 100% that the Jato is much faster than the volcano, there is no comparison and i have all i can do to get 50 out of it. I am not putting redcat down, they are fast, the volcano seemed to keep up with my mt but it stripped gears before i could really tell.
