A three blade prop will not slow it down faster. For that, you need a large swept area, low pitch, and low idle. The AFS will actually fight the pilot when making turns. NOT good for novices. There are many, many trainers out there that fly just great without the flaps, leading edge slats, and speed brakes. The Nextstar will, too. Take all that crap off, have an experienced pilot retrim it, and go fly. Put an 11-4 prop on it to control top speed and give some prop braking.
