I did loops easily, but rolls and inverted can only be done good with the advanced wing. I used the stock motor. Are you planing to use the slinger batteries on anything else after? If thats the reason for getting those batteries then my advice is dont. They're too big for most park flyers and too heavy for aerobatic type planes. Theyre pretty much only good for the Slinger or DC3 which theyre desinged for. But again youre using brushless so I dont know what kind of perfomance you will be getting out of that combo...I never used brushless.
