Well Bob, it's like this, I was playing with my CG in an attempt to get the dive out of it when I rolled inverted, just trying to make it more neutral. I moved it back 2 days ago by changing battery location, it flew fine but still had a little dive. My bright idea of moving my tank back as close to the CG as possible seemed good at the time. Last night around 10:30 I got the tank moved and re-plumbed, all ready to go. The brain fart happened when I neglected to move the battery back to the original location.
Checking the balance this morning before I loaded the van, obviously with the tank empty, it was just where I flew it the day before, no sweat, I'm ready to go!
Problem was, as I'm sure you already figured out, I no longer had the 14 oz. of fuel in the nose, 10 feet of takeoff roll and I'm airborne.

This is not going to be good!! I bled off about half a tank of fuel and tried twice to get it down without running out of room. On the third attempt the bank to final looked sweet, about 10 feet off the deck, all that's left to do is a little left rudder, bring the tail around and let her settle in, can't go wrong. Slide in a little rudder and &$#%@& what the heck was that!!! Snap and Bam, the crackle and pop came right after that.

Well over 100 flights in practice, plus last years contest's.

Painful, just painful. I need another bird.
