A large radio-controlled glow aircraft inspired by the Fairchild PT-19

The PT-19 Giant 90-120 from Seagull Models is a large semi-scale radio-controlled aircraft that captures the distinctive lines of the Fairchild PT-19, an iconic American training aircraft from World War II.

With its 2.02 m wingspan, this model does not go unnoticed on an aeromodelling field. Its proportions, low-wing monoplane silhouette, and decoration inspired by the historical aircraft give it a true semi-scale presence.

The PT-19 Giant 90-120 is aimed at hobbyists looking for more than just a leisure plane.

It combines the enjoyment of a large wooden airframe with a versatile design that allows for leisure flying, sporty maneuvers, and some aerobatics practice.

The manufacturer's documentation describes the PT-19 as a model intended for intermediate to advanced pilots, with a design that achieves a sturdy yet relatively light airframe.

A Semi-Scale Replica of the Fairchild PT-19

The Fairchild PT-19 was a training aircraft used to train US military pilots.

Its original design was characterized by a low wing and an open cockpit, giving it a particularly recognizable silhouette even today.

Seagull Models sought to preserve this identity in its radio-controlled model.

The PT-19 Giant thus benefits from a decoration faithful to the original and numerous elements that enhance its semi-scale character.

The airframe notably receives an Oracover finish, while certain exterior details contribute to the model's realistic appearance.

The result is a semi-scale RC airplane that can fit in perfectly among historical models and warbirds at an aeromodelling field.

An Immediately Recognizable Silhouette

The large 2.02 m size allows for a more realistic reproduction of the PT-19's proportions compared to a smaller model.

The relatively long fuselage, low wing, and open cockpit give the model a particularly realistic look when flying at low altitudes.

For RC airplane model enthusiasts, this type of airframe also provides an excellent foundation for gradually adding details and customizing the model.

Traditional Balsa and Plywood Construction

Like many large Seagull models, the PT-19 Giant is based on traditional construction using primarily balsa and plywood.

This construction method remains highly valued in aeromodelling for large airframes.

Balsa helps limit weight while maintaining good rigidity, while plywood is used in areas requiring more strength.

Seagull's documentation indicates that the airframe is built with balsa and plywood to achieve a robust structure while keeping weight under control.

This construction directly contributes to the model's character: the PT-19 Giant has a true traditional model aircraft architecture, rather than a molded airframe or one made solely from composite materials.

Factory-Prepared Airframe

The PT-19 Giant is delivered in an ARF (Almost Ready to Fly) version.

Much of the construction and finishing work is done at the factory. The hobbyist does not have to build the fuselage and wings entirely before starting the equipment installation.

Seagull's documentation specifically states that the motor mount and hinges are already prepared, reducing the assembly time required.

The ARF option is an interesting solution to enjoy a large semi-scale model without having to spend several months building a complete airframe.

15 to 20cc Glow Engine Power

The PT-19 Giant 90-120 is primarily designed for glow engine power.

For a 2-stroke engine, the recommended range is around 15 to 20cc. The model can also accommodate a 20cc 4-stroke engine.

This engine displacement range is perfectly suited to the size and weight of the model.

The hobbyist can choose an engine that suits their flying style and desired performance.

PT-19 15cc or 20cc: Which Engine to Choose?

A 15cc engine provides a smoother and more realistic performance.

The 20cc engine offers more power reserve and allows for a wider range of aerobatic capabilities.

The choice will also depend on the type of engine used, its weight, and the selected propeller.

For 4-stroke engine enthusiasts, the option of using a 20cc engine is particularly appealing for this type of historical aircraft. The sound and throttle response of a 4-stroke engine align well with the spirit of a semi-scale model like the PT-19.

A 2-Meter RC Airplane with Strong Presence in Flight

With its 2,020 mm wingspan, the PT-19 Giant clearly belongs to the category of large radio-controlled airplanes.

This size offers several advantages.

The model is easily visible from a distance, even during relatively distant flybys. The large fuselage also allows for a more faithful reproduction of the proportions of the actual plane.

With a wingspan of over two meters, it also has a significant presence on the field while remaining reasonably portable for a large model.

The length reaches 1,490 mm, while the wing area is approximately 62 dm². The flying weight is reported to be around 5.4 kg.

Behavior suited for leisure flying

The PT-19 Giant is not only meant for display or slow flybys.

It is a true RC leisure and sport plane, capable of dynamic maneuvers while maintaining the expected realism of a semi-scale model.

The low-wing configuration and large wing area provide behavior suited for leisure flying.

The model can be used for:

• relaxing flights;
• realistic flybys;
• track circuits;
• approaches and landings;
• loops;
• rolls;
• reversals;
• moderate aerobatics.

The marketing material categorizes it as a standard 3-axis model suitable for leisure flying, intended for a pilot already capable of handling a high-wing aircraft.

A radio-controlled plane for experienced pilots

Despite its accessible behavior, the PT-19 Giant should not be considered a beginner RC plane.

With a weight of around 5.4 kg, a wingspan of over two meters, and a 15 to 20 cm³ glow engine, it requires good piloting skills.

The Seagull documentation recommends this model for intermediate to advanced pilots.

I would recommend it to modelers who have already gained experience with smaller RC planes.

Transitioning to a model of this size requires mastering:

• energy management during approach;
• flight paths;
• altitude control;wind effects;
• landings with a large model;
• management of a glow engine.

A simple and robust fixed landing gear

The PT-19 Giant is equipped with a fixed landing gear.

This solution prioritizes simplicity and reliability.

There is no need to add the complexity of a retractable landing gear system, allowing for a relatively simple mechanical setup.

The landing gear also contributes to the model's realistic silhouette.

For regular use on a modeling field, this simplicity is a significant advantage.

A large semi-scale model for detail enthusiasts

The PT-19 Giant also serves as an excellent base for modelers who enjoy gradually enhancing their models.

The large fuselage size allows for adding various finishing details without them becoming disproportionate.

Enthusiasts of semi-scale RC planes can work on aspects like the cockpit, exterior details, and certain decorative elements.

The original version already has a particularly detailed presentation, with a decoration inspired by the real plane and a finish aimed at reinforcing its historical character.

A model suited for customization

The appeal of a large semi-scale model also lies in the customization possibilities.

You can keep the provided decoration for an immediate realistic look or use the model as a base for a more personalized presentation.

The dimensions of the PT-19 also make it easier to add details compared to a smaller fuselage.

The ARF format: an interesting compromise

Building a large wooden plane from a traditional kit is a significant project.

The ARF format of the PT-19 significantly reduces this phase.

The fuselage is already largely prepared and decorated. The modeler mainly needs to perform the final assembly and install the power system and radio equipment.

The engine, propeller, and radio control system need to be obtained separately.

This format allows for enjoying a large semi-scale model without having to complete the entire construction.

What radio system to use for the PT-19 Giant?

The PT-19 is a 3-axis model requiring a radio setup suitable for a large fuselage.

The marketing specifications indicate a 6-channel configuration, with more servos needed depending on the version and setup chosen.

It is important to choose servos that are powerful and reliable enough for the various control surfaces.

On a model weighing over five kilograms, the quality of servos, linkages, and radio power supply should not be neglected.

Mechanical play should be minimized to maintain precise and consistent control.

PT-19 Giant: an RC plane for history enthusiasts

The choice of the PT-19 is not based solely on its flight characteristics.

It also appeals to modelers passionate about aviation history.

The Fairchild PT-19 is one of the iconic training aircraft of the World War II era. Reproducing this aircraft in a large scale allows you to capture some of its historical character while enjoying the true pleasure of flying.

The Seagull model thus combines three particularly sought-after aspects in aeromodelling:

historical aircraft, semi-scale model, and large radio-controlled thermal aircraft.
