You are going to love the way the Mid-Star 40 flies, may mine RIP![&o] It's really sturdy and loves to be abused and when you want to slow down and fly like a sane person it will do it for you, so enjoy! If I were to build another one I would change out the balsa wood spars for hardwood as the ones supplied with the kit were way to soft and I also used hardwood spars in the turtleback.
