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.
removable hatch
The large hatch with spring-loaded latch allows for easy radio gear access and LiPo battery changes. A pilot bust is included and installed.
aileron servos
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.
