Ultimate Jets - Phoenix Mk2 assembly manual - Revision 2 - 08/11/2013
INTRODUCTION
The Phoenix MK 2 is our new jet trainer. It is full composite, delivered assembled and painted.
It is designed for jet beginners with following objective :
-Very easy to fly.
-Short take off and landing due to big airfoil thickness (13%), large flaps and low wing loading
-Very fast assembly
-Easy access to engine (top engine, no hatch, no exhaust pipe)
-Easy access to fuel tank , ECU and radio thanks to a large fuselage hatch.
-Easy radio installation thanks to the large fuselage hatch and supplied servo covers.
The model comes to you finished and painted in mold. All the CNC machined bulkeads are glued. All
the control surfaces are live hinged. No gluing is required. This model has plug in type wings, stabs and
fin booms for an easier transport.
All necessary hardware are included in the kit ( options available like the kevlar tank and gear )
Assembly require only few hours to fit engine and radio.

Gear :
Please, use only the struts supplied by Ultimate Jets.
If you use standard struts, you will have to modify the gear
position and the fuselage reservations.
Fasten the main retracts on the plywood mount using the M4
x16 mm socket head screws provided.
Fasten the front gear on the plywood mount .
Secure the front retract with four 4x16 mm
socket head screws.
Fasten the steering servo inverted on the plywood frame
Connect servo to steering arm with 2 mm ball link + steel wire
You might want to drill a 3 mm hole in the bottom of the fuselage
to access the servo spline screw.
The strut steering arm should be connected
thanks to a pull-pull system and crimping
tubes. Just loop the wire around the arm tight
and crimp. On the servo side, use a stiff servo
arm or disc. The 2 mm ball links on the servo
side will help in adjusting the tension . Do not
make it too tight or you might restrict the
down lock.

If necessary, add 2 springs or rubber to bend the steel wire when the gear retract
Connect all air tubing and brakes according to the manual.
Secure all tubing with stainless steel safety wire.
The air tank can be fitted either in the nose or in the
fuselage on the side of the main tank.

(you can also glue it with silicon glue
for improved safety).
Place the servo cover on the boom.
Drill four 1 mm holes through the
covers into the booms.
Cut a slot in the control surface for the
fiber control horn.
Glue the control horn with Hysol
E20HP.

of the hole of the wing root for the servo
harness.
Drill this hole on both sides of each
boom.
Solder the rudder electric harness.
Make a 5 mm hole in the boom in front of the stabilizer root to pass the harness.

Secure the wings :
Slide the wing tube through the fuselage.
Install the left and right booms .
Take care to put the tube at the center (same lenght left and right;
about 200 mm).
Install the left and right wings.
A plywood tab is already installed in the wings for the screw
locking system
It is located at 190 mm from the wing root
A pre drill is already done in the wing for the screw location
Make a 2.5 mm hole throught the wing and aluminium tube to secure
the wings.
Taper the wing tube and wing at M3. Secure the wings with a
M3x30 socket head screw.
It is also possible (but not necessary) to secure the
aluminium tube in the fuselage, so that the wing tube
won’t move during transportation.
Drill a 2.5 mm hole in the center of the fuselage from
the gear bay. Drill the hole throught the plywood frame
and aluminium tube to secure the tube.
Fasten a 3 x 16 mm parker screw through the plywood
and aluminium tube, so that the tube will not move
during assembling and de-assembling.
If you don’t secure the tube, just make a line with a pen at the wing root to easily find the good tube
position during assembling.
Secure the horizontal stabilizer :
Install the stabilizer between the 2 booms.
Secure it with two M6x40 nylon screws.

Fuel tank
Connect the fuel tank to the clunk as per the photo.
Check that there is no leak before fitting it into
fuselage.
Drill a 3 mm hole at the bottom of the fuselage to
install a fuel vent.
The fuel tank is connected to the small catch tank
(200 cc) or UAT catch tank to make sure that there
will be no bubbles in the fuel line.
The tubing from the main tank to the catch tank and from the catch tank to the fuel pump must be
gasoline tubing (no silicone tubing). This applies to the
vent line as well.
The catch tank is glued with double face tape on the
bottom of the fuselage close to the main tank or with
rubber band to the main tank.
Hold the fuel tank with rubber bands or silicon glue.
Filling the fuel tanks :
Connect your pump and fill the system in direction of the
tank. It will first fill the catch tank and then the main tank.
The main tank will be full when fuel drops from the vent
line.
When the tanks are full, close
the filling system.
Do not ever close the air vent
tube except possibly for
transport.
The system is ready for engine
start.

Engine installation :
The engine must be secured with four M3x20 mm sheet metal screws onto the rear turbine reservation.
A plywood reinforcement is already glued inside the fuselage
For small engine like the P60 or Merlin 100, the engine mounts will not be large enough to be screwed
on the fuselage.
In this case, cut mounting plates from 3 mm aluminium or carbon fiber.
Make all the necessary holes in the fuselage for the electric harness as well as the fuel tubes in front of
the engine.
ECU installation :
Fit the ECU on one side of the plane.
Fit the fuel pump and the valves just aft of the ECU and hold them with tie wraps.

Radio installation :
Install the radio equipment in the front section with the batteries in the nose initially.
Adjust the batteries position to set the correct CG position.
Don’t put the received and aerial antenae too close the the ECU
The retract valve and brake valve can be fitted as per the pictures.

Center of gravity
You'll need two 2200 Mah battery + one ECU battery of the capacity recommended by the engine
manufacturer to get the correct position of the Centre of Gravity.
Note : balance the model with the gear down and the tank empty but air trap full.
The center of gravity (CG) must be located at 140 mm to 150 mm rear of the wing leading edge (wing
root)
The aircraft must adopt a slightly nose down attitude when balanced. If it is horizontal or the tail drops,
move the battery forward or add weight in the nose.
On the other hand, if the nose drops considerably add weight in the tail.
140 mm is the maximum forward CG position. 150 mm is the maximum aft CG position.
Total weight
The total weight of the Phoenix should be 7.5 kg dry. The tank capacity of 2.2 liters permits a flight
endurance of 6 minutes with our Merlin M100XBL ( with an additional go-around reserve of 2 minutes
). This engine represents the optimal choice in terms of fuel consumption to weight ratio for this plane.
For more hard core 3D aerobatics we'd recommend our BF-Turbines B100F that outputs 120N of thrust
in the same form factor. However the fuel consumption is higher and the endurance will be reduced to
5 minutes.
Important note : Pay a very careful attention to structural integrity. This jet can reach speeds of
over 400 KPH - 250 MPH. It is your responsibility to operate it safely.
Specifications may change without notice.
