Airbus H130 BIG
The H130 is designed to extend the AS-350 series. Its official name is therefore AS 350 B4, as its approval is based on the AS 350 B3, whose main rotor system has been adopted.
In particular, noise was a major concern, as some areas of tourist interest were not allowed to be flown over by the previous helicopters due to noise. The first feasibility studies took place in 1998. It was shown that an asymmetrical Fenestron together with a variable rotor speed allows a corresponding noise reduction without the need for expensive new developments.
FAA certification was granted on 14 December 2000 and JAA certification on 21 December 2000. The launch customer in 2001 was Blue Hawaiian Helicopters, which received a pre-series copy in February 2001. The base price was US$ 1.6 million in 2002 and around US$ 3.1 million in 2010. The series machines were delivered from September 2001. In December 2004, the 100th machine was handed over to a customer. In February 2012, Eurocopter announced the development of the EC130 T2. The further development of the basic version features a modified engine with lower fuel consumption and longer maintenance intervals, combined with higher power (max continuous 850 hp, take-off power around 950 hp). The helicopter’s fuselage has been redesigned by 70%, especially to eliminate problems with deformation phenomena of the old version (e.g. warped doors) .
The H130 has a three-blade main rotor and a Fenestron as tail rotor. It is powered by a single turbine equipped with a digital control system (FADEC-Full Authority Digital Engine Control), has room for 7-8 passengers and has a newly developed landing gear that suppresses resonance phenomena more effectively than before. Technically, the aircraft is based on the Eurocopter AS 350, but has a larger cabin, which is air-conditioned. The first flight took place on 24 June 1999.
As a special feature, the flight control system allows the main rotor speed to be lowered in order to reduce in-flight noise. At 84.3 EPNdB, it is 0.5 dB below the GCNP (Grand Canyon National Park) limit. For comparison, a modern Boeing 737-800 jet causes 79.1 dB, while the standard private jet, the Cessna 172 with modern noise protection, causes 66 dB.
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 parts was done in 6 moulds. High-quality resin systems are used to produce high-strength, very light-weight components, which in the end produce all parts necessary for the construction of the EC 130 / T 2.
The tail is bolted to the fuselage as a separate part.
A set of frames made of high-quality aircraft plywood is resin-coated in the fuselage and takes care of the tank, landing gear and turbine or electrical mechanics.
The finished model has doors that can be opened or pushed like the original.
Windows are fitted from the inside and fixed with superglue.
The landing gear is equipped with a boarding aid which is attached to the landing gear with scale mounting parts.
The cladding of the turbine-gearbox area is fitted with closure replicas. Various air inlets on and around the fairing complete the scale replica.
Optionally the fuselage can be upgraded with stern linings with rivet replicas, quick release fastener replicas. This is done after the assembly and the first preparation for painting.
Further optional available additional equipment such as cockpit, LCD monitors, interior seating, searchlight, winch 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 variant H 130 / T2 is built with the scale Flex rotor head 3 blades with a scale 3 blade swashplate.
Mechanics HF H-130 for Jakadowsky turbines Pro 5000 and PRO 6000 or Hacker Q 100.
Robust mechanics specially designed for EC 130.
Sturdy 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 spacer bars. It 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 EC 145 and is specially milled for us from the solid. This ensures 100 % concentricity. The plastic main gear then meshes with the pinion of the centrifugal clutch of the Jakadowsky turbine.
High-quality bearings complement the mechanics and allow for a long service life.

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 without any problems and over a very long life time. These torques occur especially in large models and must be compensated by the Fenestron.
