You are going to really like this plane. We (my friends and I )have five E-Starter's. We have thrown every battery we own at this thing and it loves them all. The 1200 lipo's are without a doubt the best that we have tried. Just make sure they are the 2cell (7.4v)and not the 3(11.1v). The motor will fry with the 3cell packs. Always balance a new plane ,but none of ours had to have any weight added to get them to balance. Going to put floats on mine this summer!!![sm=drowning.gif]
