The Hangar 9 Extra 330L accepts gas engines ranging from 60
through 80cc’s. The prototype Extras were flown using Zenoah
G-62s and Zenoah GT-80s. The G-62 offers good sport
performance and is a good choice for doing all IMAC basic and
sportsman maneuvers. While the G-62 equipped Extra doesn’t
quite provide unlimited vertical performance, most experienced
sport flyers find that the G-62 offers plenty of power for all but
the most aggressive types of aerobatics.
If you’re a 3D fanatic or an Advanced or Unlimited IMAC class
competitor, Zenoah’s GT-80 offers unlimited power for vertical
multiple snaps, hovers, and torque rolls. In fact in it’s first-ever
IMAC contest, Mike Mcconville and Peter Goldsmith took first
and second place respectively in Freestyle using the GT-80
equipped Extra.
