MB339 XS 1.9m
ARF
EDF or P60-130 turbine
ASSEMBLY MANUAL
The all new MB399 XS 1.9m ARF was designed by Italy
aerobatic pilot Sebastiano Silvestri. This semi scale ARF jet-
model design is based real aircraft design and modifided adding
the ultimate aerodynamically ideas of the modernst pattern models
and using the 20 years experience in flying jets the
result is surprising!
This innovative design combined with the lightweight structure,
the fiberglass fuselage and all wood airframe wings and stabs,
give the MB339 XS 1.9m ARF an impressive precision and
smoothness at any airspeed and flight condition. Thanks of his low
wingload, with powerfull setup EDF or turbine powered, it can be
a fantastic aerobatic jet-trainer… let you surprise from your new
MB339 XS ARF !
.....the only aerobatic-fun limit is your fantasy!

Warning
This RC aircraft is not a toy!
If misused, it can cause serius bodily harm and damage to property. Fly only in
open areas, preferably in official flying sites, following all instructions included
with your radio and motor.
Before starting assembly
Before starting the assembly, remove each part from its bag and protection for a prior
inspection. Closely inspect the fuselage, wing panels, rudder, and stabilizer for
damage. If you find any damage or missing parts, contact the place of purchase.
If you find any wrinkles in the covering, use a heat gun or covering iron to remove
them. Use caution while working around areas where the covering material overlap to
prevent separating the covers.
Warranty information
SebArt garantees this kit to be free from defects in both material and workmanship at
the date of purchase.
This warranty does not cover any parts damage by use or modification, and in no case
shall SebArt’s liability exceed the original cost of the purchased kit.
Further, SebArt reserve the right to change or modify this warranty without notice. In
that SebArt has no control over the final assembly or material used for the final
assembly, no liability shall be assumed or accepted for any damage of the final user-
assembled product. By the act of using the product, the user accepts all resulting
liability.
If the buyer is not prepared to accept the liability associated with the use of this
product, the buyer is advised to return this kit immediately in new and unused
condition to the place of purchase.
RADIO SET UP
For a more realistic jet fying, more safe, stable and easy in the wind, we recommend
to install, especially for the turbine application, the Power Box Mercury SRS with
GPS.
We suggest to use the Power Box internal sequenzer for adjust the door servo and
timing. We suggest to use a separate channel for the steering servo, to mix ON with
gear down only.
Flaps:
We recommend to use flaps down for starts and landings to make them shorter and
easier.
Activate the FLAP function in your radio.
For start use approx. 20° flaps down and mix 12% elevator down
For landing use approx. 50° full flap down and mix 18% elevator down
Control throws:
For the AILERON we recommend the following throws:
Use approx. 10% aileron differential (more up) for normal flight.
High rate: 30° left & right
Normal flight: D/R: 80% Expo: 10%
Snap, spin: D/R: 100% Expo: 25%
Start & landing: D/R: 100% Expo: 25%
For the ELEVATOR we recommend the following throws:
High rate: 35° up & down
Normal flight: D/R: 40% Expo: 35%
Snap, spin: D/R: 100% Expo: 80%
Start & landing: D/R: 100% Expo: 80%
For the RUDDER we recommend the following throws:
High rate: 35° left & right
Normal flight: D/R: 80% Expo: 15%
Snap, spin: D/R: 100% Expo: 30%
Start & landing: D/R: 100% Expo: 30%
Note: the Expo is (+) for JR systems, and (–) for Futaba systems.
Mixing:
We recommend the following mix (if you have a programmable computer radio):
Rudder →Elevator DOWN
full rudder to the right, the elevator have to go down (negative) approx. 3%
full rudder to the left, the elevator have to go down (negative) approx. 3%
Rudder →Ailerons
full rudder to the right, the ailerons have to go left approx. 6%
full rudder to the left, the ailerons have to go right approx. 6%
Recommended Center of Gravity
The recommended CG is
165mm
behind the leading edge of wing.
Pre-flight
Never attempt to make full throttle dives! This model have to be flown like a full-
scale airplane. If the airframe goes too fast, such as in a high throttle dive, it may fail.
Throttle management is absolutely necessary.
Range test your radio
Before fly, be sure to range check your radio as manufacturer’s instruction
manual of you radio-system recommend.
Double-check all controls (aileron, flaps, elevator, rudder and throttle)
move in the correct direction.
Be sure that your battery pack is fully charged, as per the instructions
included with your batteries and that your radio is fully charged as per its
instructions.
have nice flights!
