Bristell B23
INTRODUCTION
Congratulation on your purchase of the semi-scale model of the Bristell B23 two-
seat trainer! You are about to start the assembly of a model manufactured from
virtually unbreakable EPO (extruded polyolephine) foam powered by a mighty
BEFORE YOU START
1. If you are not an experienced R/C pilot, plan to have a fully competent
pilot check your completed model and help you with your first flights.
Even though we have tried to provide you with a thorough instruction
manual, R/C models are rather complicated and an experienced mode-
ler can quickly check over your model to make sure your first flights are
successful.
2. Please assemble your model exactly according to these instructions. Do
not attempt to modify or change your model in any way as doing so may
adversely change its flying characteristics.
3. Before you begin, please check the entire contents of this kit to make sure
that no parts are missing or damaged. This will also help you to become fa-
miliar with each component of your plane. If you find that any of the parts
SAFETY PRECAUTIONS AND WARNINGS
• An R/C aeroplane is not a toy! If misused, it can cause serious bodily harm
and damage to property. Fly only on a safe place following all instructions
and recommendations in this manual. Beware of the propeller! Keep loose
items that can get entangled in the propeller away from the spinning pro-
peller, including loose clothing, or other objects such as pencils and screw-
drivers. Ensure that yours and other people's hands, and face are kept away
from the rotating propeller.
• As the user of this product, you are solely responsible for operating it in a
manner that does not endanger yourself and others or result in damage to
the product or the property of others. This model is controlled by a radio
signal that is subject to interference from many sources outside your con-
trol. This interference can cause momentary loss of control so it is advisable
to always keep a safe distance in all directions around your model, as this
margin will help to avoid collisions or injury.

MODEL ASSEMBLY

1. Trial the fit of the horizontal and vertical tailplane and the fuselage - no
glue yet (Fig. 2+3). Double check the parts fit tight and the fin is vertical to
the horizontal stabilizer (Fig. 4). If necessary sand the parts to fit.
2. Connect the rudder servo to the extension cable in the fuselage (RUDD)
and secure the connectors with a piece of heat shrink tube, bind them
together with a dental floss or secure with a strip of sticky tape. Apply
medium or rather thick cyano (or clear silicone or MS polymer glue) to the
contact area of the fin and attach the fin to the fuselage. (Fig. 2)
3. Connect the elevator servo to the extension cable in the fuselage (ELEV)
and secure the connectors with a piece of heat shrink tube, bind them
together with a dental floss or secure with a strip of sticky tape. Apply
medium or rather thick cyano (or clear silicone or MS polymer glue) to the
contact area of the horizontal tailplane assembly and attach it to the fu-
selage. (Fig. 3)
4. Before the glue sets double check the fin was vertical to the horizontal
stabilizer (Fig. 4).
5. Slide the wing halves onto the wing tube joiner; arrange the aileron and

are either missing or damaged, please contact your dealer immediately
for replacement.
Note: Your dealer cannot accept kits for return if construction has begun.
4. Trial fit each part before gluing it in place. Make sure you are using the
correct part and that it fits well before assembling. No amount of glue can
make up for a poor fitting part.
5. The manual contains drawing showing the default position of the Centre
of Gravity (CG) and recommended control surface throws. Please note it is
essential to keep the recommended CG position for the first flight other-
wise the model could be unstable, hard to control or even unable to fly
at all! Later you can fine tune the CG position to suit your flying style and
skills.
• Never operate your model with low transmitter batteries.
• Always operate your model in an open area away from power lines, cars,
traffic, or people. Avoid operating your model in populated areas where
injury or damage can occur.
• Carefully follow the directions and warnings for this and any optional sup-
port equipment (chargers, rechargeable batteries, etc.) which you use.
• Keep all chemicals, small parts and anything electrical out of the reach of
children.
• Moisture causes damage to electronics. Avoid water exposure to all equip-
ment not specifically designed and protected for this purpose.
• The model is mostly made of plastics - it is not fireproof. It may not be ex-
posed to higher temperatures otherwise severe distortion of the foam air-
frame or other damage may occur.

flap servo cables and the LED light cables onto the upper side of the wing.
(Fig. 5)
6. Thread the servo and LED light cables into the cockpit and attach the wing
to the fuselage. Attach the main undercarriage to the bottom of the wing
and secure it together with the wing to the fuselage using two 3.0x40 mm
bolts. (Fig. 6)
7. Insert the nose gear into the bracket in the fuselage, remove the cano-
py. Slide the nose gear arm onto the nose gear wire and secure it with
M3.0x10 mm setting screw. (Fig. 7+8+9)
8. Attach the propeller to the prop driver and secure it with the propeller
nut with a washer; tighten the nut using No. spanner. (For your safety, you
should better leave the propeller installation after your radio is all conne-
cted and set and the correct direction of rotation of your motor had been
tested.) Secure the spinner using M2.5x22 mm bolt in place (Fig. 10)
9. Attach a strip of a hook-and-loop (the loop part, not supplied in the kit)
to the bottom of your flight pack and secure it with the hook-and-loop
fasteners to the battery seat in the cockpit. (Fig. 11)
