To get 10-15 minutes flying time with an electric, you pretty much need to get a brushless motor/ESC and LiPo battery pack setup. The SuperStar EP Select comes with a brushed motor/ESC and a NiCd pack, so your probably going to get about 5-10 minutes of flight time. Getting higher capacity NiCd or NiMH batteries might extend that, but then you'll be adding weight, and it won't fly as well. From what I've heard, the stock motor/ESC/batt barely flies it, so adding more weight may not be a great idea.

The ESC that comes with it probably doesn't have the proper voltage cutoff for LiPo packs.

If I were you, I'd get an ElectriStar. It comes with a brushless motor/ESC and a radio system. You can buy some NiCd or NiMH battery packs for it to save some $$ initially, and I'm told it flies fine as a trainer with that setup. Later on you can upgrade to LiPo batteries, save about a pound in weight, and it will fly longer and be more sporty/aerobatic.
