One of the NC dyno gurus was having issues with catastrophic tire failures on one of his RC cars. Apparently, the car weighs around 20 lbs. This was his solution… [quote=“BigDyno”"] Yeah, we can dyno that.

What fun is having a car that can go that fast, if it can’t do so without coming apart? It’s not about the cost of the tire, it’s about figuring out what needs to be done to get the thing to stay together at speed. Sure, he could slow the car down, but what’s the fun in that? Do we slow our “full scale” cars down, or do we test and upgrade parts so that they will hold up to the stresses we need them to withstand at full tilt…? I could really give 2 shits either way, I’m just playing devil’s advocate here FYI… ---

What needs to be done, is a AWD conversion. Coming from someone that deals in RC’s cars all the time. I rarely see RWD RC’s not losing control at that speed. I have several cars that will do well over 100mph and are AWD that dont even tweak at high speeds. I understand he has more of a drag car, but its the wrong design for that kind of use. ---
