Customer reviews and experiences

What do pilots say about the Giant-Scale model?

Most owners of the true-scale J-3 Cub report an extremely satisfactory flight experience. The model is praised in particular for its stability in the air and the true-scale flight properties. Many pilots mention that the flight behaviour is very close to the original, which is particularly important for enthusiasts of authentic aircraft models.

An experienced model pilot from the middle west of the USA reports: "The flying characteristics of the big cub are impressively gentle. He literally glides through the air like his great role model. Particularly in the case of light wind, the stability is fully effective."

Several reviewers praise the quality of prefabrication and precision of fit. A German model flyer writes: "The processing is first-class, the covering immaculate and all prefabricated parts fit perfectly together."

However, there are also some critical voices regarding the guidance, which is sometimes perceived as insufficiently detailed, especially for less experienced model builders.

Material quality and processing

The construction of balsa wood and light plywood offers an excellent ratio of stability to weight. The UltraCote® film covering is appreciated for its longevity and authentic appearance. Especially the true-scale details such as the clear windows, wing struts and strut wires give the model a realistic look.

A customer with 15 years of model flight experience reports: "The material quality surpasses many other ARF models in this price class. Especially the quality of the wood parts and the careful processing are positive."

Air quality

Flight times

Flight times of 12-15 minutes can be achieved with a suitable 4S LiPo battery. When using a 5S or 6S LiPo battery, the flight time is extended to up to 20 minutes, depending on the flight style. Even longer flight times are possible with an internal combustion engine.

Increased power

The gradient power depends strongly on the selected drive configuration. With the recommended 4260-480Kv external rotor motor and a 6S LiPo battery, the model shows an impressive gradient which is more than sufficient for true-scale flights. A customer reports a rise rate of about 20-25 degrees, which is quite realistic for a Cub.

When using an 11cc 4-stroke petrol engine, the gradient is also very satisfactory and allows realistic start and rise sequences.

Transport and storage

A sophisticated feature of the model is the two-piece wing with special cutouts in the fuselage for receiving the wing tube during storage and transport. This considerably facilitates transport and at the same time protects sensitive components.

Transportability is considered excellent by many customers. A pilot from Australia reports: "The transport to the airfield is easily possible due to the removable support surface. Even in a small car, the model finds room when you take off the wings."

Spare parts supply

The spare parts supply for the J-3 Cub is generally rated as good. Horizon Hobby, the manufacturer behind the Hangar 9 brand, offers an extensive range of spare parts that can be purchased from various specialist dealers worldwide.

Particularly frequently asked parts such as suspension components, rudder flaps and small parts are generally available quickly. For more specific components, longer delivery times may occasionally occur.

Target group

The flight model is primarily aimed at advanced to experienced pilots (level 3). The size and weight of the model require a certain degree of experience in handling larger models. Beginners should first gain experience with smaller, less complex models.

A club member from a large model flight club remarked: "The big Cub is definitely nothing for absolute beginners. But it is ideal for pilots with solid basic knowledge, who want to switch to a larger, true to scale model. The good-natured flight characteristics also forgive minor errors."

Assembly and construction

How long does the assembly take?

The manufacturer specifies an assembly time of 20+ hours, which is confirmed by most customers as a realistic estimate. Experienced model builders can possibly complete assembly in 15-18 hours, while less experienced craftsmen should plan 25-30 hours.

Quality of construction instructions

The construction instructions are described by most customers as sufficient but not exceptionally detailed. The illustration is helpful, but some customers want more detailed explanations for more complex assembly steps.

A German model maker remarks: "The guide is fine, but in some places it is kept somewhat tight. With some experience in model construction, you can understand all the steps. For newcomers it could be challenging in some places."

Community support

An active community has developed around the large-format Cub. In various online forums and social media, owners exchange themselves through modifications, settings and flight tips.

Particular emphasis should be given to:

• Special Facebook groups for Hangar 9 models
• Threads in big RC forums like RCGroups
• YouTube channels with construction and flight tips

These community resources can be particularly valuable when it comes to specific questions about optimization or problems that are not sufficiently dealt with in the guide.

Tips, tricks and optimizations

Motorization options

For the electric setup recommend experienced pilots:

• When using a 6S LiPo battery a somewhat smaller propeller (13x8 instead of 14x8) to reduce the engine load
• An additional cooling air inlet for the ESC during intensive use
• Use high quality extension cables for the wing servos

For the burner variant:

• A fuel filter in front of the carburetor prevents engine problems
• The installation of an additional fuel tank can significantly extend flight times
• A good silencer system significantly reduces the noise level

Priority optimization

The manufacturer's centre of gravity (3-3,75"/76-95mm) is a good starting point. Many experienced pilots report, however, that a slightly head-loaded focus (approximately 3.25"/83mm) gives the best flight characteristics.

Improving scale accuracy

For even more realism recommend enthusiasts:

• Installation of a true-scale pilot figure
• Adding a detailed instrument board
• Add additional scaling details such as rivets and maintenance flaps
• Use of abrasion-resistant stickers for registration numbers

Transport optimizations

• Special transport bags for the wings protect against damage
• Removable rudders facilitate transport in smaller vehicles
• Special holders for fastening in the trunk prevent damage during transport

Frequent questions and solutions

Question: How long does the initial construction last for an average model builder?

Answer: Most model builders with medium experience need about 20-25 hours to assemble the ARF kit. The time varies according to the level of experience and the selected drive system. The electric version is usually mounted slightly faster than the burner version.

Question: Is the model suitable for art flight?

Answer: The Cub model is primarily designed for true-scale flying and not designed for demanding art flight. However, it can handle simple art flight maneuvers such as loopings, rollers and turns when equipped with a powerful motor. Specialized models should be preferred for intensive art flight.

Question: What battery size is recommended for optimal flight performance?

Answer: Most pilots report the best results with 5S 5000mAh LiPo batteries that offer a good balance between performance, flight time and weight. When using a 6S battery, attention should be paid to the total weight in order not to adversely affect the flight properties.

Question: Are there any known vulnerabilities on the model?

Answer: Some customers report the need to strengthen the mounting of the suspension struts, especially when started and landing on uneven terrain. In addition, the bonding of the hinges before the first flight should be checked, since occasionally reworking is required.

Question: Can the model be equipped with swimmers?

Answer: Yes, the model can be equipped with separately available floats. It has special devices for mounting float struts. However, the installation of swimmers increases the total weight and influences the flight characteristics, so that a slightly stronger motorization is recommended.

Question: How is the model in wind?

Answer: Like his role model, the J-3 Cub is relatively wind-sensitive. In the case of light to moderate wind (up to about 15 km/h), the flight behavior is still easily controllable. With stronger wind, however, flying becomes increasingly demanding. The large-format version is slightly more wind-stable than smaller Cub models, but still windy conditions should be avoided.
