The Aérospatiale SA 341 is a helicopter produced as a co-production between the French manufacturer Aérospatiale and the British manufacturer Westland Aircraft. It is used in at least 23 countries with a wide variety of armaments to attack targets such as armed vehicles, other helicopters, slow flying objects and infrastructure.
In 1966, work began on a light five-seater multi-role helicopter to succeed the successful Alouette II, which was to be technically less complex. The SA 340 prototype flew for the first time on 7 April 1967, although it still had a conventional two-blade tail rotor. The newly developed 13-bladed and shrouded Fenestron tail rotor was only used in the second prototype. The three GRP blades of the jointless main rotor were a joint development with Bölkow GmbH; the concept was similar to that of the Bölkow Bo 105. However, due to problems with the control at high speeds, the jointless rotor head was replaced by a movable rotor system. [1]
The first SA-341 production helicopter took off on 6 August 1971. After various versions for the French (still active in 2016) and the British military (decommissioned in 2018), the SA 342 appeared, which was equipped with a more powerful turbine. Until March 2009, the British Army Air Corps still had several “Gazelles” stationed in Germany at Elmpt/Lower Rhine. The SA 342 was produced by Aérospatiale, Westland and under licence by SOKO (Yugoslavia) as Gazela.
Matching kit components
Kit
The master model was created according to original Eurocopter documents. On a large 5-axis milling machine, the master model parts were milled in Uriol and then prepared so that the required negative moulds could be produced.
The production of all GFK / CFK parts is done in 11 moulds. High-quality resin systems are used to produce high-strength, very light-weight components, which in the end produce all the parts necessary for the construction of Aérospatiale SA 341.
The stern is resin bonded to the hull as a separate part and is designed for the installation of a highly effective Fenesrtron from Jürgen Schwing’s design. As in the original, the Fenestron is driven free-running by a stainless steel tube. Storage is done via 3 bearing points.
A set of frames made of high-quality aircraft plywood is resin-coated in the fuselage and takes over the tank, landing gear and turbine or electrical mechanics.
The finished model has doors that can be opened.
Windows are fitted from the inside and fixed with superglue.
The landing gear is time-shifting (right and left side) and is attached to the frame set with aluminium clamps.
The special feature of this model is the position of the turbine. The turbine can be found at its original position on the model.
This way the whole area of the turbine fairing and the exhaust pipe could be reproduced exactly like the original sale.
A special mechanism from Heli-Factory holds the turbine in the turbine fairing. This made it possible to create a completely free cockpit for the scale conversion.
Optionally the fuselage can be upgraded with stern linings with rivet replicas, quick lock replicas. This is done after assembly and the first preparation for painting.
Further optional available additional equipment like cockpit, interior seating, landing lights, armament etc. can be ordered separately depending on the model and let your helicopter become a unique scale replica of your dream helicopter.
To optimise the weight, the new tail boom is constructed in CFRP / GFRP and is extremely light with extreme torsional stiffness.
The version Aérospatiale SA 341 is built with the scale “Gazellen” rotor head 3 blades with a scale 3 blade swashplate.
Mechanics
Mechanics HF- Gazelle/BT for Jakadofsky turbines PRO 6000 or electric drive with Q 100.
Robust mechanics specially designed for the Gazelle and the position of the turbine.
Stable GRP side plate screwed onto aluminium bars milled from the solid form the base frame of the mechanism.
An original bevel gear set from Jakadowsky is placed between the distance bars, which was manufactured with high precision and is driven by a main gear made of high-strength plastic. This main gear is designed for the desired speed of the rotor head for the Gazelle and is specially milled for us from the solid. This ensures 100 % concentricity. The plastic main gear wheel then engages with the pinion of the centrifugal clutch of the Jakadowsky turbine or electric motor.
High-quality bearings complement the mechanics and allow for a long service life.

Drive
The 8-blade Fenestron is completely made of aluminium and has a gearbox with a bevel gear combination 1:1 with a diameter of 23.3 mm. The bevel gears have cyclo-palloid teeth module 0.6.
And the tooth flanks are induction hardened.
This gives us a very high strength and allows us to transmit high torques over a very long service life without any problems, especially with large models, which have to be compensated by the Fenestron.
Fenestron equipped with 8 aluminium blades. Mounting of the Fenestron in the tail boom via 3 stator holders.
Fenestron completely in metal. All parts manufactured for us on high-precision 5-axis machining machines according to our drawings and layouts.
Fenestron with gearbox completely assembled and gear backlash adjusted in the gearbox. The stator holders are included with the Fenestron.
Drive via multiple ball bearing rigid drive guided in an aluminium tube with connection couplings.
