The new Ultrafly YAK-54 is specifically designed for extreme aerobatic maneuvers. Compared to most other small aerobatic balsa models which were developed using a direct scale duplication of a TOC design, our specially designed thick airfoil provides much better lift for performing slow speed modern aerobatic maneuvers. The wing-loading of this airplane will match to many larger 60-120 size glow engine model. That is to say, you may enjoy a great flying performance with only limited budget and forget about all those trouble of a glow engine model. Trust us when we say with our design you can “feel” the difference!
