Yeah,you'll want something a tad bigger then that .40. As Kat said.....a .46 would be a good choice. And In my "opinion",dont get an evolution( I hate 'em!). If you can afford it,get an O.S. Anything but an evolution,lol. A .40 will get you off the ground,but barely. And get yourself a good field charger like a hobbico Quick Field Charger mkII and a battery for it. There are about 100 other things you'll want,but this is my couple recommendations.
