Are you looking for a versatile model aircraft that is suitable for both sports flight and light art flight maneuvers? The smaller version of the popular Hangar 9 classic could be just the right one for you. In this detailed guide you will learn everything you need to know about this 69-inch model, from technical specifications to expert reports and practical tips.

Technical data and specifications at a glance

Before we dive into the details, here is a clear summary of the most important technical data of the model:

The high-quality flight model is designed as ARF (Almost Ready to Fly), which means that it is delivered to a large extent pre-assembled. The construction is based on light, laser-cut balsa wood and plywood, which ensures a low weight while maintaining high stability.

Construction and assembly: Faster into the air than thought

assembly and construction time

The assembly of the Valiant 10cc model is comparatively simple. With an estimated construction time of 10-15 hours, it is one of the models that can be completed relatively quickly. Most components are prefabricated and only have to be screwed.

Only the height guide, the lateral fin and the control surfaces must be glued in. All hinge slots and holes, including the ones for the flaps, are already prepared on the work side, which considerably facilitates assembly and makes the process more comfortable on the construction table.

Quality of construction instructions

The model’s construction manual is well structured and includes detailed step-by-step instructions with helpful illustrations. Especially for model builders with some experience, the guide is very understandable. For absolute beginners, it could be a bit more detailed in some places, which is compensated by numerous online tutorials and community support.

Material quality and processing: Longevity meets lightweight construction

The sports aircraft model impresses with its high-quality processing and the use of high-quality materials. The hull and the wings are made of light but stable balsa wood and plywood, which have been precisely laser-cut. The covering with real UltraCote not only ensures an attractive appearance, but also a long service life.

The hood and wheel linings made of lacquered fiberglass give the model a realistic look and offer good protection at the same time. The wide-track suspension of lacquered aluminium ensures excellent soil adhesion and allows start-ups and landings on less optimal grass pistes.

The two-piece push-in wing without struts gives the model not only a stylish look, but also makes the construction on the field a child's play. The large front flap offers convenient access from above and allows easy battery replacement, especially for the electric variant.

Flight characteristics and performance: A dream in the sky

Flight time and range

With a 10cc petrol engine like the recommended Evolution 10GX you can expect long flight times. The small 7.5 ounce tank is inexpensive to fill and is sufficient for flight times of about 6-8 minutes, depending on the flight style and engine setting.

In the case of the electrical variant, the flight time strongly depends on the selected battery configuration. With a 4S LiPo battery with sufficient capacity, similar flight times are possible as with the petrol variant.

climbing performance and art skills

The model convinces with impressive flight characteristics. With folded-up flaps, it is a true sports art flight dream machine with dramatic looping capabilities from any location, crunchy rolling behavior and sufficient side rudder authority for impressive blade flight solutions – particularly remarkable for a high-decker model.

The functional flaps significantly expand the flight spectrum and give the STOL (Short Take-Off and Landing) model, which is particularly advantageous for smaller airfields.

Transportability: Practical for travel

Thanks to the two-piece push-in wing without struts, the aircraft can be easily transported. The wings can be easily removed, allowing the model to be placed in almost any car. In transport, however, sufficient upholstery should be ensured in order to avoid damage to the covering.

The relatively low weight of 3,2-3,7 kg also makes the model handy and easy to transport without special transport devices being necessary.

Spare part supply: Well supplied in case of damage

The spare parts supply for the sports aircraft is excellent. As a product of an established manufacturer such as Hangar 9, spare parts are readily available via various dealers such as Horizon Hobby, Tower Hobbies or specialized model building shops.

Many standard parts such as servos, linkages or motors are also compatible with other models, which additionally facilitates the search for spare parts. In the case of larger structural damage, standardised balsa wood and plywood panels can be used in many cases, which are available in any well-sorted model shop.

Target group: From advanced beginners to experienced pilots

The flight model is aimed primarily at advanced beginners and experienced pilots. For absolute beginners, handling could initially be a bit challenging, although the stable flying characteristics of the high-decker are basically beginner-friendly.

The versatility of the model makes it particularly attractive for pilots looking for an all-round aircraft that is suitable both for relaxed cruises and for light to medium-heavy art flight maneuvers. Also model flyers that want to move from electric to petrol drive find an ideal entry model here, as it is designed for both types of drive.

Tips, tricks and optimizations

Motorization recommendations

For petrol drive:

• Evolution 10GX is the ideal choice as the model has been designed
• Alternatively, other 10cc two-stroke or 11cc four-stroke engines also work well
• Pay attention to the correct propeller size according to engine recommendation

For electric drive:

• A brushless motor with 800-1000W power is recommended
• 4S LiPo batteries with at least 3000mAh offer good flight times
• High-quality ESCs with at least 60A ensure reliable operation

Priority

The correct focus is crucial for good flight characteristics. Experienced pilots recommend that the center of gravity be set exactly according to instructions and then, if necessary, adjusted after the first test flights. For more precise art flight maneuvers, a slightly head-loaded focus can be of advantage.

Rudder and Expo settings

For beginners, a more conservative setting of the rudder rudder rudders with higher Expo values (30-40%), is recommended to make the control less sensitive. Experienced pilots can increase the outputs and reduce the Expo values for more direct response behavior.

Optimization for different flight styles

For relaxed cruises:

• Folding easily extended for more lift
• Reduced gas setting for longer flight times
• Moderate rudder rudders for gentle control reactions

For art flight:

• flaps completely retracted
• Maximum rudder stops
• Focus on adjusting slightly head load
