I love my Laser too! it seems to have no weakness in it's flight envelope, it's just great at everything! It looks fantastic too.
Mine is powered by a Motrolfly DM-2820-750kv spinning a Xoar 13x7, Gens Ace 2200mAh, 30c, 4s, Savox servos all round. Only thing to watch is the Laser will come out nose heavy if you use any power set up heavier than the one I'm running. It needs to balance at the former behind the wing tube for close to neutral CG and even with my relatively light battery that is only achieved with the battery hard up on the wing tube. You could of course add tailwaight but I'd hate to have to do that
