Introduction

Introduced in 1977, the Christen Eagle II was the brainchild
of avid aerobatic pilot and entrepreneur, Frank Christensen.
His idea? Give pilots a refined, aerobatic kit plane almost
anyone could build. The sporty little two-seater was so
well-received that a slightly modified, single-seat version
became the plane of choice for one of the greatest aerobatic
demonstration teams of all time-Charlie Hillard, Tom
Poberezny and Gene Soucy, otherwise known as The Eagles.
The trio flew the plane from 1979 through 1995, thrilling
millions at air shows all over the world.
The Hangar 9 Christen Eagle II 90 ARF brilliantly captures the
spirit of this remarkable airplane. Constructed of top quality
balsa and light plywood, it will eagerly perform extreme
aerobatics just like its full-scale inspiration using your choice
of glow or brushless electric power options. And it comes
out of the box with a level of scale fidelity that truly sets it
apart from the rest of the sport model crowd.
If you're a sport flyer ready for more advanced planes or
an aerobatic pro looking for a fun, sport scale model, the
Christen Eagle II 90 has what you're after.
