C G issues.....

OK, so I slapped my battery in and Maiden-ed this little guy. I could tell it was pretty tail heavy from the start. I input some down trim and this helped a little, but not near enough....Out of a turn it just wanted to climb and climb and climb.....It did handle the 5 - 8 mph wind pretty well.....So, I brought it in and decided to try it with the landing gear on. The gear is a little forward of the specified CG. Same issue...flew it for a while still trying to get a good feel. I had a fairly slow speed power-off crash into the ground. Absolutely no ding on the spinner, but it broke the left wing off in half!

So, I CAed it back on and looks OK.. So I decided to check my CG, and sure enough, it balances back on around 25-26 mm back from the leading edge. Not sure why so peoples fly OK. Like some others, any of you that have had your plane fly great right out of the box.....would really like to know what your CG is at!
