Congratulations on your purchase of the Extreme Flight RC Extra 300 58 inch Electric
ARF. This aircraft was designed to provide maximum performance and fun in a great
looking, lightweight, easily transported, fully aerobatic ARF aircraft. Using a powerful
and efficient brushless outrunner motor and speed controller and a single high discharge
5S1P Lithium Polymer battery (3300-5000 mah), the 58 inch Extra provides unlimited
precision and 3D aerobatic performance capability.
Great care was taken to design a light weight yet robust airframe. Expert engineering
and modern laser cutting methods in conjunction with a carbon fiber wing tube and
composite control horns keep weight to a minimum. Unique features such as the 2 piece
plug in wings mounted on a carbon fiber wing tube, pre-mounted canopy and spring
loaded canopy/hatch latch make for quick easy assembly and instantaneous access to the
interior of the plane and battery tray. The Extra also features a high quality set of carbon
fiber landing gear, PILOT X series helmet head pilot bust and detailed dash/instrument
panel. Getting the Extra in the air is quick and easy! The Extra can truly be assembled in
a couple of evenings-buy it on Friday, fly it on Sunday!
As with all Extreme Flight RC airplanes, fight performance is second to none! The
Extra flies precision aerobatics remarkably well and allows you to practice your IMAC
sequences almost anywhere. The long tail moment makes for a plane that tracks like a 2
meter pattern ship and the lightweight wings minimize over rotation in snaps. You’ll be
amazed at how well this thing flies the sequences.
Of course the Extra will perform all of the 3D moves with ease. Incredible yaw, pitch
and roll authority allow the Extra to obey your every stick command. Sport flyers fear
not! With reduced rates the Extra is a very easy plane to fly. Its super light wing loading
allows it to land at a walk. It will instill confidence and allow you to improve your flying
skills. When you’re ready for more advanced aerobatics, flip the dual rate switch and
hang on!
As with any high performance aerobatic aircraft, great care must be taken to avoid
excess speed. Excess speed could lead to control surface flutter and quite possibly the
complete destruction of your aircraft. Don’t let this happen to you! Always have the
motor at idle when the airplane is pointed down and reserve full throttle for vertical
climbs. Make sure you have adequate mechanical advantage in your control linkage set-
up. If you are unsure about this, have a more experienced flyer look over your set-up
before flying. Extreme Flight RC, Ltd. in no way warranties its aircraft against flutter.
As with all of our planes, we put the Extra through a rigorous flight testing regime and
have not experienced any control surface flutter. It is your responsibility to ensure the
airworthiness of your aircraft.
The 58 inch Extra was designed around the new Torque Revolution 4014T/570
Brushless Outrunner motor and Airboss Elite 80 Amp ESC with SBEC. This is the best
choice for powering the Extra, providing plenty of power for any maneuver imaginable.
Other outrunner motors in this class will work as well but may require slight modification
to the motor mount. We also recommend the use of the Hitec HS-5245mg digital mini
servo for aileron and elevator. The standard HS-225MG is also a good choice. We used
a standard size digital servo for rudder (Hitec HS-5475). The HS-475 is also a good
choice. Please take a few minutes to read this manual before beginning assembly to get
familiar with the process.
