En 2009, Milan Bříštěla, un concepteur d'avions tchèque de renom, a fondé avec son fils Martin la société BRM AERO Ltd. Leur premier avion, le Bristell Classic, un élégant biplace ultraléger à aile basse avec un train d'atterrissage tricycle, a connu un succès retentissant (plus de 600 exemplaires vendus dans le monde). Depuis, l'entreprise a continué de croître et d'élargir sa gamme de produits.

Le dernier ajout est le Bristell B23, un avion à ailes basses entièrement métalliques à deux places avec un train d'atterrissage principal composite certifié selon l'AESA CS-23/U.S. 14 CFR (FAR) Partie 23. Le B23 "pleine grandeur" doté d'un cockpit moderne entièrement en verre et de la dernière avionique est un entraîneur parfait pour les écoles de pilotage ainsi qu'un avion confortable pour le vol amusant et les voyages en distance.

Avant de commencer

Si vous n'êtes pas un pilote RC expérimenté, prévoyez de demander à un pilote pleinement compétent de vérifier votre modèle complet et de vous aider avec vos premiers vols. Même si nous avons essayé de vous fournir un manuel d'instructions complet, les modèles RC sont plutôt compliqués et un modélisateur expérimenté peut rapidement vérifier votre modèle pour s'assurer que vos premiers vols sont réussis.
Veuillez assembler votre modèle exactement selon ces instructions. N'essayez pas de modifier ou de changer votre modèle de quelque manière que ce soit, car cela pourrait modifier négativement ses caractéristiques de vol.
Avant de commencer, veuillez vérifier l'intégralité du contenu de ce kit pour vous assurer qu'aucune pièce n'est manquante ou endommagée. Cela vous aidera également à vous familiariser avec chaque composant de votre avion. Si vous trouvez que l'une des pièces est manquante ou endommagée, veuillez contacter immédiatement votre revendeur pour un remplacement.
Essai d'adapter chaque pièce avant de la coller en place. Assurez-vous d'utiliser la bonne pièce et qu'elle s'adapte bien avant de l'assembler. Aucune quantité de colle ne peut compenser une pièce mal ajustée.
Le manuel contient un dessin montrant la position par défaut du centre de gravité (CG) et les lancers de surface de contrôle recommandés. Veuillez noter qu'il est essentiel de conserver la position CG recommandée pour le premier vol, sinon le modèle pourrait être instable, difficile à contrôler ou même incapable de voler du tout ! Plus tard, vous pouvez affiner la position CG en fonction de votre style de vol et de vos compétences.

Précautions et avertissements de sécurité

An RC aeroplane is not a toy! If misused, it can cause serious bodily harm and damage to property. Fly only in a safe place and follow 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 propeller, including loose clothing, or other objects such as pencils and screwdrivers. Ensure that your 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 control. 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.
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 support 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 equipment not specifically designed and protected for this purpose.
The model is mostly made of plastics – it is not fireproof. It may not be exposed to higher temperatures, otherwise severe distortion of the foam airframe or other damage may occur.

Set contents

Almost ready to fly model with the brushless motor, speed controller and servos installed, instruction manual. (Fig. 1a+1b)

You will also need

At least 6-channel RC set, 14.8 V 2600–3300 mAh LiPo flight pack.
Regular modeller’s tools: modeller’s knife (KAV66.770), screwdrivers, pliers, No. 10 spanner, sandpaper etc.
Glue: Medium or thick cyanoacrylate glue (e.g. KAV56.9952 or KAV56.9953), silicone or MS polymer glue.

Model assembly

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.
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 dental floss or secure them 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)
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 dental floss or secure them 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 fuselage. (Fig. 3)
Before the glue sets, double-check the fin is vertical to the horizontal stabilizer. (Fig. 4)
Slide the wing halves onto the wing tube joiner; arrange the aileron and flap servo cables and the LED light cables onto the upper side of the wing. (Fig. 5)
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 3.0×40 mm bolts. (Fig. 6)
Insert the nose gear into the bracket in the fuselage and remove the canopy. Slide the nose gear arm onto the nose gear wire and secure it with an M3.0×10 mm setting screw. (Fig. 7+8+9)
Attach the propeller to the prop driver and secure it with the propeller nut with a washer. (For your safety, leave the propeller installation after your radio is all connected and set and the correct direction of rotation of your motor has been tested.) Secure the spinner using an M2.5×22 mm bolt in place. (Fig. 10)
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)
B23 - Receiver connection
Remove the connection board cover and hook up your receiver, servos and ESC following the wiring diagram right. The receiver is to be secured with a strip of double-sided foam tape or hook–and–loop tape to the rear part of the cockpit. Deploy the antennas, so their active parts are square to each other (if you are using a receiver featuring diversity antennas).
Note: The kit is supplied with the connection board for ailerons, flaps, rudder and the steerable nose gear, so you can use even the most basic 6-channel radios to control your Bristell B23. If you intend to use independent control of aileron and flap servos and an advanced computer radio, you will have to replace the default Y-cables with four 25–30 cm extension cables.

The LED lights are only powered via the connection board. They are not remotely controlled in any way.
With your radio on, set the servos to the neutral position (sticks and trims centred) and fasten the setting screws of the pushrod connectors on the elevator and rudder servo arms. Perform the throttle range calibration of the ESC as described in the attachment of this manual.
Attach the canopy.
Use medium cyano to glue the dummy antennas (Fig. 13) and pitot tube. (Fig. 14)

RC set installation and pre-flight check

Referring to the instruction manual of your radio, carefully hook up the on-board electronics.

Once everything has been correctly connected, turn on your transmitter and plug in the flight pack. Check the neutral positions and throws of all control surfaces. If you need to make the control surface throws smaller, simply move the pushrod closer to the centre on the servo arm or move it far from the control surface on the control horn. And vice versa.


Recommended throws	Low rate		High rate
Recommended throws	Rate	Expo	Rate	Expo
Ailerons	± 13 mm	30–40 %	± 20 mm	40 %
Elevator	± 13 mm	30–35 %	± 20 mm	35 %
Rudder	± 26 mm	25–30 %	± 40 mm	30 %
Flaps	Take–off: -12 mm down / Landing: -30 mm down

The "Low rate" recommended control surface throws are suitable for a less skilled pilot and regular "scale" flying. The "High rate" setting allows an experienced pilot to explore the full capabilities of this model.
Check the direction of rotation of the propeller. If it is incorrect, simply swap two of the three wires between the ESC and motor or program the ESC (refer to the ESC manual).
Check the correct position of the centre of gravity (CG): 75–85 mm behind the leading edge of the wing (Fig. 15). Adjust the CG position by moving the flight pack - if you cannot reach the recommended position, do not hesitate to add an appropriate amount of lead to the nose or tail. An extra couple of grams won’t spoil the flying characteristics - but the incorrect CG position is a killer.
Fully charge your flight pack and transmitter batteries, check the proper function of your radio and perform the range check of your radio according to its instruction manual. The range has to be almost the same with the motor off and at full throttle (no more than a 10% decrease is acceptable). DO NOT try to fly unless the range check is 100% successful.

Flying

The test flying and fine-tuning is pretty much straightforward. There will be no surprise for a medium-advanced pilot who is supposed to fly this model.
