When I purchased this plane it took me a minute to dial it in. Some foam removal in the nose to accommodate an 800 MAh 3s slightly front of the CG. Do not put the Lipo where they tell you in the wing pocket over the CG this is too tail heavy.
I love this plane It flies like an ME-109 with thin wings should. FAST and on rails. It does not like slow turns use speed and rudder. when coming in to land keep wings level and use rudder with slight power and gentle glide slope.
I have buried the nose more than 3 times learning this plane so it is NOT for a beginner or even some intermediate. It is durable with some good care and the right kind of glue for those breaks.
A good plane :)
