Hi my name is John and I'm from midwest Canada province of Manitoba. I recently bought a Blitzworks 5ch RC F16 Thunderbird version EDF(#2149) from Banana Hobby. Challenge I have is I wanted to use a larger capacity LiPo than comes with it. So I bought Zippy 2800mah 4S 30C and now find it is a bit bigger than battery compartment(bought it before I had plane). Battery size is 120mmX36mmX37mm. Anyone familar with the plane and any suggestions? Thanks!
