I'm the world's biggest idiot......Saturday my friend and I went flying (my second time at the controls), and besides the horribly foggy weather, the plane flew great and I did very well at the controls. We fly at an old abandoned airport, and I have a pickup truck that I use the tailgate as a platform for the plane and accessories. I've been using a full size 12 volt battery (trolling motor battery) to power the starter until my hobby box is built with a standard size rc battery. Anyway we flew for about an hour or so, and decided the fog was getting worse. So we brought his plane and my plane down, loaded up our trucks and took off. I was within a few miles of home when I had to hit the brakes relatively hard to avoid a car that pulled out in front of me. Guess where the unsecured battery went......You guessed it, right into the side of the tail section in the back of the pickup. When I looked at the damage I was horrified, nearly obliterated the whole tail. After a few choice words, I put the plane away and later looked at it. Most of the left rear fuselage was crushed, but after a few hours of epoxy, CA, and extra balsa this thing might actually fly again...Sorry this was so long, but don't be a fool and secure eveything in your vehicl when you transport your plane.
