I did the maiden this weekend-the lipo came in at about 37% charged which is lower than others i received. 40 minutes on the trusty 4s FMA charger and up she went. WOW very fast and stable. Grass take-off was about 5' and did not require any trimming that I could tell-windy out. Anyway flight was fun and no bad suprises-just good ones. Run for about 8 minutes easy and used up 50% battery power.
