I tell people all the time to never let others drive your RC car. Ever. Learned That the hard way. Years ago, I bought an Ofna Pirate 10. Look it up. It was a 1/10 scale truck with a Picco .21 crammed into it. Crazy, stupid fast and could spin a glued tire off the rim. Or shred them. Not kidding. Finally got the motor broken in, and found a set of wheels and tires that might take the abuse. My brother stopped by. He had several RC's at the time. Took a couple minutes to test the throttle and steering. Then he punched it! Spun several donuts and threw a rear wheel. Didn't hit anything, but twisted the axle right off. He just calmly handed the remote back to me as my jaw hit the floor. Nobody had any axles and it took nearly a month to get one from Italy.
My kids found out the hard way too. We love to bash and don't need help breaking things.
