I bought the combo which came with the Thunder Power 1320 11.1v. I believe that is the correct info. Thanks for all your help. I have been unable to learn 3d on anything because even my 1.40dz on my DPM Ultimate doesn't have enough power!! Thin air really sucks. I fly full scale as well, and let me tell you, i just avoid flying in the summer all together. The tower is always telling me to clear the runway right after take off, and i am always having to say I am too low. Anyhow, I'll quit my whining. I am pretty sure the electric and super low weight of this plane will do the trick.
