Just thought I'd update you on the progress with my EZ*.

I now have logged over 90 minutes of flight on it. Although I haven't made any mods to the plane itself, I have:

-Created a home-made battery pack. This gave me nearly 25 minutes of 1/2 throttle flight!
-Put tape around the top of the wings where it fits into the model. It was getting loose.

I also was able to fly inverted today. It wasn't has hard as I thought it would be. The stock motor doesn't seem to have enough power to flip the plane over. I took it up really high and put it into a steep dive and then turned it over. No problems at all. Wasn't nearly as hard as I thought it would be.

I didn't stay inverted long. About 5 seconds and then just put back into a dive and climbed out again.

Repeat 5x. Good fun.
