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, pre­mounted 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.

Tips for Success-Please read before beginning assembly!!!

1. Read the instruction manual thoroughly before starting assembly.

2. We are very pleased with the level of craftsmanship exhibited by the workers in our
factory. However, these are mass produced models. As with any ARF, take a few
minutes to go over the model and add CA to high stress areas or any joints that appe ar to
need more glue. Specific areas to pay attention to are servo mounts, landing gear
mounting plate, firewall to fuselage side joint, wing root rib and motor box joints. A few
minutes and a few drops of CA will help to insure the longevity of your model.

3. Make s ure your prop and spi nner are balanced ! These aircraft perfor m as well as the y do
because they are built light. Excess vibration caused by unbalanced components can
cause damage to the airframe.

4. Buy a Watt meter! For less than the cost of a single battery pack you can purchase one of
these. This will save you a lot of time, money and frustration and p rovide you with a lot
of valuable information about your set up. One battery pack saved is worth this
investment!

5. Observe the C rating of your batteries. If your battery is rated at 2100 mah and 20C
continuous discharge rate then you can safely pull 42000 mah or 42 Amps from it (2100
x 20= 42000 mah=42 Amps). Use a watt meter between your battery and ESC to
determine the number of Amps you are drawing as well as the number of Watts you are
generating. I have found it is best for battery longevity if your maximum amp draw at
wide open throttle is in between the continuous rating and the burst rating of the battery.
Prop your airplane accordingly.

6. We have done a lot of experimenting with various props. Using the Torque 2814T/820 on
4S we like the APC 12x6E. Remember to test each new prop size with a Watt meter
attached to the system to be sure you are not overworking any of the components.

7. Decals- clean your airplane with glass cleaner and a paper towel before st arting to apply
the decals. Mist the area where the decal will be applied with glass cleaner or water
mixed with a little bit of soap. Use scissors to remove the de cal from the s heet. For bes t
results cut as clos e to the edges of the decal as possible. Posit ion the decal in place and
use a credit card or rubber squeegee to push the excess liquid from under the decal and
allow to dry. You may need to secure the edges of the decal with masking tape to
prevent them from rolling up until the solution has dried and evaporated.

PLEASE NOTE-The assembly process for the Vanquish MKII is
virtually identical to that of the original Vanquish. Most of the
pictures in this manual are of the original airframe. Anywhere this
process deviates from the original assembly process photos of the
new assembly method will be provided.

Wing assembly

1. Locate a wing panel. Check to see that all hinges are centered between the wing and
aileron. Hold the aileron fully deflected and apply a drop of thin CA to each hinge.
Flip the wing over and repeat.

2. Use a #11 hobby blade to remove the covering over the servo bay. Install the aileron
servo using the manufacturer supplied mounting screws. You will need to attach a 6
inch extension to the servo lead. Route the servo lead out of the root of the wing.
