Flyermark,
Congratulation and good news on your madden flight, intended or not. I'm also flying on grass and it makes the landing rather tough.
I haven't tried a third flight as I'm searching for a field with a runway.

I'm still having a tail heavy problem and by battery needs to be as far over the motor as possible(with additional 6 ounces). I really think I got one of the earlier kits that had the major problems.
