Ive made a lot of what was I thinking comments, like forgetting my fuel, charger, etc. Only one I can think of now is what happen today. I was getting the motor mount screws out from my friend losi muggy. We we at it for 45 minutes. It was a huge hex, and it came with his vehicle but we were using pliers and everything to get it out. Then I asked somone over at my house if he could help, as he was stronger....got it right out. Come to think of it, I was turning the hex wrench the wrong way!
Now when I take out screws I always say "lefty loosy righthy tighty".
The one about your friend forgetting his radio is still making me laugh!
