From Great Planes:
For years the Ultra Sport has been the epitome of what a sport aerobatic airplane should be: quality construction, versatile performance and contemporary style. The 4th iteration of the Ultra Sport incorporates the most up-to-date features, resulting in an Almost-Ready-to-Fly model that sport pilots and veterans alike will enjoy.
- Flies well with glow OR electric power.
- Included mechanical retracts enhance performance and style.
- Large hatch for easy access to on-board gear and battery.
- The symmetrical airfoil offers a wider aerobatic range.
The Ultra Sport .46/EP ARF is designed to easily accept a .46-size glow engine or comparable size electric motor, and performs great with either option.
Mechanical retracts boost the Ultra Sport’s overall performance. With the gear up the plane flies faster and looks sleeker — when the gear is down ground handling is solid and predictable.
The large hatch with spring-loaded latch allows for easy radio gear access and LiPo battery changes. A pilot bust is included and installed.
Separate aileron servos allow for more precise control and trim adjustments, as well as customized mixing options.
The cowl is made of high-quality fiberglass, and complements the plane’s balsa and plywood construction.
