Thank you for your purchase of the Extreme Flight RC Vanquish MKII Electric ARF. The
original Vanquish released in 2007 was designed to provide maximum performance and fun in a
great looking, lightweight, fully aerobatic park flyer while using an inexpensive and efficient
brushless outrunner motor and speed controller and a single high discharge 4S1P Lithium
Polymer battery. The Vanquish MKII features several notable improvements over the original,
providing even better flight performance and an improved feature set. Among these improved
features are an airfoiled tail group, allowing for even better tracking, a lightweight airfoiled
carbon fiber landing gear and carbon fiber tailwheel assembly. In addition the wing has been
raised and the stab lowered to further reduce coupling and the rudder servo has been moved to
the rear of the aircraft to provide a short direct linkage for rudder actuation.
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, 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 Vanquish MKII can truly
be assembled in an evening-buy it one day, fly it the next!
As with all Extreme Flight RC airplanes, the proof is in the flying! The Vanquish MKII flies
precision aerobatics remarkably well and allows you to practice the AMA pattern or FAI F3A
sequence 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. On a calm day you’ll be
amazed at how well this thing flies the sequences.
Of course the Vanquish MKII will perform most all of the common 3D moves, but its true
calling is precision aerobatics.
Sport flyers fear not! With reduced rates the Vanquish MKII 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 will 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 Vanquish 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 Vanquish MKII was designed around the Torque 2814T/820 Brushless Outrunner motor
and Airboss Elite 45 Amp ESC with SBEC. This is the best choice for powering the Vanquish
MKII, 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.
The Vanquish MKII is very easy to assemble. Take a few minutes to read this manual before
beginning assembly to get familiar with the process.
