I don’t have one because for the money I think I’d rather get a real RC vehicle, like nitro powered that does 35 mph and can drive over rocks and take really big jumps. Don’t get me wrong, Vex is cool and worth the price, but even though RCs aren’t customizable out of the box like Vex, they are extremely capable out of the box which Vex isn’t.
Vex will never take big jumps or go 35 mph. RC gives more speed for the dollar.
Vex wins as the better tool in an educational setting while I’d say RCs win as the better tool in a recreational setting.
