Ken, Gene.. A couple of years ago, one of our club members came to me and asked me if I could help re'maiden their Senior Cadet. They crashed and he and his son rebuilt it. They put an OS 90 on the thing. It was way overpowered, but that's the way they wanted it.

Anyway, I flew it and it flew like a brick.. either all throttle, or it was not going to fly. But, it needed some adjustments to the CG so I told them that it did.. and they played with it. When I walked over to the thing, well, they were using wrenches over the fuel tank as nose weight... and I mean wrenches!!!

So, tools, in this case intentional, are not that far fetched.
