I ask the question because... Yesterday, my brother-in-law and sister dropped by while I was driving my T-Maxx. They just moved home from Alaska and have been wanting to see my r/c's. To make a long story short... I reluctantly handed over the controller and let him drive for a bit. He drove it around for a second to get the feel and then decided to drive it near some trees. Of course you know what happened... Straight into a tree at about 3/4 throttle. Luckily, the grass was long and thick so it wasn't going extremely fast and nothing broke. I got the truck turned around and figured he would take it easy... Well, I thought wrong. 30 seconds later the truck was hung up in a bush. Then 30 seconds after that it was tearing through some boxwoods and it ended up stuck on a fence rail. Finally, the truck ran out of gas and the demolition derby ended before any damage was done. So all these events led to my question. Do you ever let anyone test-drive your R/C cars and trucks?
