update after first flight

Hi

Performed first flight a couple of weeks ago with a 5S3000 20c lipo.
I hand launched my F4J and that went well.
Had to do some down trimming and boy she was fast.
Flies stable and after a few minutes land plane check lipo and saw my lipo moved a bit forward thats why my CG changed.
Well all back in place second hand launch this was a bit more tricky and flying again well.
After some runs I decided to land and fly pattern but lipo was empty. lost speed and hight and F4J went down, only cockpit a little damaged and some fuselage damage.
Repair was easy and ready for flight again.
Weight of plane no lipo is 1030 gram
