RE: i mastered a sim now what
as long as your on the buddy box, i think a low wing trainer would be okay. something like a sky raider mach II would serve you well. naturally a million people and their mothers would recommend the four star so they can't be all that wrong either :-)
actually, come to mention it, the best low wing trainer i've ever flown (but never owned) was a world models supersport. they come in 30 and 40's and are wonderful flyers and easy as heck to land. if anything i recommend that plane. my friends who are terrible flyers look like veterans on that plane. plus it's quite acrobatic and wicked fast as well.
