I exploded one big time....BUT I can tell you that I should have known it was coming.
Before I had wheelie bars, I was riding out wheelstands pretty high and far. Well eventually it caught up to me. I stood the car up on the bumper, and it was one of those " rear wheels off the track" wheel stand. That's all it took to roll the sprag, the rear tires came off the ground under power. Next pass it BLEW and I mean BAM! ! ! on the starting line. I should have known that it could have rolled the sprag, and should have taken the car home and inspected it before raing again.

IF you race a T flite, you have to be aware of what causes sprag damage and if you think you hurt the sprag….DONT race the car, until you make sure. Im pretty sure its almost always a broken sprag that allows the drum to overspeed and explode.
