I've had 5 Aeromasters, obviously a love affair. They fly great. Most guys overpower them. My latest is flying on a vintage ST .51 and has plenty of zip. Don't shy away from the Ultimate. It's a great "pure" flying machine. I fly and like a lot, my 1/3 scale Pitts. It's fun to fly, but not very precise. Too much coupling. I just started flying a 1.20 size Pitts Monster 12, Goldberg ARF I found. Great kit and great flyer. BUT, the best, was the Goldberg Bucker Jungman. Wish this one would come back. A tremendous flyer, the best of all so far. Could be flown very precise.
