I'm no electric pro, but that would definitely be too heavy.

Now I have a question. I am interested in this plane, but I need REDICULOUS vertical power without adding REDICULOUS weight. I have a 1320 3-cell and Phx-25 esc, what motor, in or out would give me the best vertical performance?
BTW, rediculous to you would be satisfactory to me, because I fly at 6500 feet...
