yeah i had 3 strip on the way in, had to back them out with pliers. its like once in a while they aren't as deep as the others so the hex slips and kills it. i have the engine to put on, glue the tires and a couple more colors on the body and she'll be ready for a LONG day at the track tomorrow, well worth the wait. i might get the hyper 7 to 8.5 conversion done too if i go quick enough.
