HPH 304TS Twin Shark – un planeur tchčque aux racines allemandes

En 1962, Eugen Hänle a fondé la Glasflügel Segelflugzeugbau GmbH, qui est rapidement devenue célčbre en tant que premičre entreprise ŕ produire en grande série des planeurs en fibre de verre. Les conceptions de Glasflügel ont toujours été reconnues pour leurs solutions innovantes, devenues des caractéristiques standards des planeurs modernes : systčmes d'assemblage rapide pour les ailes et les empennages, combinaisons de volets d'aérofreins au bord de fuite, conception pratique des cockpits et des systčmes de contrôle, et bien d'autres. Malheureusement, aprčs la mort prématurée du fondateur dans un accident d'avion en 1975, l'entreprise a rencontré des difficultés financičres. Elle a finalement été dissoute en 1982.

Au milieu des années 1990, une jeune entreprise tchčque nommée HPH, déjŕ reconnue comme fabricant de modčles réduits de qualité muséale, a relancé la production de l'un des derniers planeurs conçus par Glasflügel : le type 304. L'usine de Kutná Hora, en Bohęme centrale, a débuté avec le HPH 304CZ fabriqué ŕ partir des moules et gabarits originaux, avant de le faire évoluer vers le HPH 304C Wasp de 15 mčtres, conforme ŕ la classe FAI. En 2006, ils ont introduit un tout nouveau design de la classe de 18 mčtres, nommé HPH 304S Shark, et enfin, en 2017, le planeur biplace de 20 mčtres, le HPH 304TS Twin Shark.

Avant de commencer

Si vous n'ętes pas un pilote RC expérimenté, prévoyez qu'un pilote pleinement compétent vérifie votre modčle terminé et vous aide lors de vos premiers vols. Bien que nous ayons essayé de vous fournir un manuel d'instructions complet, les modčles RC sont assez compliqués, et un modéliste expérimenté peut rapidement examiner votre modčle pour s'assurer que vos premiers vols seront couronnés de succčs.
Veuillez assembler votre modčle exactement selon ces instructions. N'essayez pas de modifier ou de changer votre modčle de quelque maničre que ce soit, car cela pourrait altérer ses caractéristiques de vol.
Avant de commencer, veuillez vérifier l'ensemble du contenu de ce kit pour vous assurer qu'aucune pičce n'est manquante ou endommagée. Cela vous aidera également ŕ vous familiariser avec chaque composant de votre avion. Si vous constatez que certaines pičces sont manquantes ou endommagées, veuillez contacter immédiatement votre revendeur pour un remplacement.
Remarque: Votre revendeur ne peut pas accepter le retour du kit si la construction a commencé.
Faites un montage ŕ blanc de chaque pičce avant de la coller en place. Assurez-vous d'utiliser la bonne pičce et qu'elle s'adapte correctement avant de procéder ŕ l'assemblage. Aucune colle ne peut compenser un mauvais ajustement.
Le manuel contient un dessin indiquant la position par défaut du centre de gravité (CG) et les débattements recommandés des gouvernes. Il est essentiel de respecter la position recommandée du CG pour le premier vol, sinon le modčle pourrait ętre instable, difficile ŕ contrôler, voire incapable de voler ! Par la suite, vous pourrez affiner la position du CG pour l'adapter ŕ votre style de pilotage et ŕ vos compétences.

Safety precautions and warnings

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 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 propeller, including loose clothing, or other objects such as pencils and screwdrivers. Ensure that your and other people’s hands and faces 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 of a sailplane with the brushless motor, speed controller and servos installed, instruction manual.

You will also need

At least 7-channel RC set, 14.8 V 2600–3300 mAh LiPo flight pack.
Regular modeller’s tools – modeller’s knife, screwdrivers, pliers etc.

Model assembly

Connect the aileron (A) and flap (F) servo cables to the corresponding extension cables in the wing opening in the fuselage. Double-check the correct connection. (Fig. 1)
Note: The kit is supplied with Y-cables for ailerons and flaps so you can use even the most basic 6-channel radios to control your TwinShark. 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.
Insert the wing halves into the fuselage and secure with the M6 nylon bolt. (Fig. 2)
Attach the horizontal tailplane to the top of the fin and secure with two M3×10 mm screws. (Fig. 3)
Attach the elevator push rod (the elevator servo is installed in the fin) to the elevator horn. (Fig. 4)
Your TwinShark is fitted for the belly landing as supplied. You might wish to add the undercarriage.
Remove the screw and the foam filler from the landing wheel bay. (Fig. 5)
Install the wheel yoke using the same screw into the wheel bay. (Fig. 6)
Insert the wheel into the yoke, attach the dummy undercarriage doors from both sides of the yoke and secure with two screws. (Fig. 7)
The flight pack is to be placed in the bay in the centre of the cockpit. Use a hook-and-loop tie to fasten it. You can place your receiver (secured with a strip of hook-and-loop or double-sided foam tape) behind the flight pack. The ESC is to be secured in the same way along the flight pack. Connect the servos and your ESC to the receiver. Deploy the antennas so their active parts are square to each other (if you are using a receiver featuring diversity antennas). 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. (Fig. 8+9)
Attach the canopy.

RC set installation and preflight check

Referring to the instruction manual of your radio carefully hook up the onboard 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.

	Low rate	High rate
Ailerons	15 mm up/8 mm down	20 mm up/ 10 mm down
Ailerons (Butterfly)	20 mm up	20 mm up
Ailerons (Thermal)	3 mm down	3 mm down
Ailerons (Speed)	3 mm up	3 mm up
Elevator	± 9 mm	± 12 mm
Elevator (Butterfly)	1–3 mm down	1–3 mm down
Rudder	± 25 mm	± 35 mm
Flaps	8 mm up/15 mm down	8 mm up/15 mm down
Flaps as Ailerons	7 mm up/3.5 mm down	10 mm up/5 mm down
Flaps (Butterfly)	20 mm down	20 mm down
Flaps (Thermal)	4 mm down	4 mm down
Flaps (Speed)	3 mm up	3 mm up

The "Low rate" recommended control surface throws are suitable for a less skilled pilot and regular soaring. The "High rate" setting allows an experienced pilot to explore the full capabilities of his model. The aileron differential (aileron down deflection reduced to 50% of up deflection) is only possible with a computer radio.
Check the direction of rotation of the propeller. If it was 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): 57–62 mm behind the leading edge of the wing (Fig. 10). Adjust the CG position by moving the flight pack - if you could not 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.
