Alternative products of competitors

There are some comparable models on the market for prospective buyers who want to consider alternatives to Piper Pacer:

Great Planes Piper J-3 Cub

A similar classic with comparable size and flight characteristics. The Cub is a bit easier to fly and forgives more mistakes, but offers less power reserves. It is priced in a similar segment to the Pacer.

FMS Piper PA-18 Super Cub

This model is offered as PNP (plug-and-play) and requires less construction effort. The flight properties are comparable, with the FMS variant being somewhat more robust by its EPO foam material when crashing, but being limited to true scale and authentic flight behavior.

Hangar 9 Piper Pawnee

A slightly larger and more powerful model for more ambitious pilots. The Pawnee offers more power reserves and is also suitable for more demanding flight maneuvers, but is also more complex in construction and operation.

In a direct comparison, the E-flite PA-20 Pacer scores with its balanced ratio of construction quality, flight characteristics and price. The wood construction conveys a more authentic flying feeling as foam models, while the ARF design significantly reduces the time required compared to complete kits.

Value for money

The Piper Pacer is positioned in the middle price segment for ARF models of this size class. Given the high quality of materials, the detailed execution and the excellent flight characteristics, the price-performance ratio can be rated as good.

It should be noted that additional components such as motor, servos, receivers and battery are required for completion, which increases the total investment. For beginners who do not yet own these components, this can lead to a considerable initial investment.

Tips, tricks and optimizations

Motorisation

Although the E-flite Power 10 Brushless external rotor recommended by the manufacturer is a good choice, alternative motors with similar performance data can also be used. A slightly stronger motorization can improve the climbing performance without negatively affecting the flight behavior.

In the propeller selection, an 11x7 or 12x6 propeller has proved to be optimal. This combination offers a good compromise between traction and speed. A quality spain in the recommended size of 1.75 inches completes the appearance and improves the aerodynamics.

Battery optimization

For longer flight times, a 3S 2200mAh LiPo battery can be used, provided that the additional weight is compensated by corresponding center of gravity adjustment. In the case of battery positioning, attention should be paid to the correct focus that has a decisive influence on the flight properties.

Servos and linkages

The use of high-quality servos with metal gear can increase reliability and allow more precise control movements. In the articulations, it is recommended to use fork heads instead of Z cranks, since they permit a more finer adjustment of the rudder deflections.

Chassis optimizations

With harder landings, the true-scale wire suspension can reach its limits. Reinforcement of the fastening points in the fuselage can improve durability. Alternatively, spring-loaded suspension legs can also be retrofitted to better absorb landing impacts.

Optical improvements

For even more scale accuracy, additional cockpit details such as a pilot figure, instrument board and seats can be installed. External details such as antennas, position lights or tank necks can also evaluate the appearance.

Frequent questions and solutions

Question: How difficult is the assembly for beginners?

Answer: The assembly of the Piper model requires basic building knowledge and experience in handling RC components. For absolute beginners, assembly could be challenging. It is recommended to seek support from experienced model builders or to gain experience with simpler models.

Question: The model tends to break when starting. What can I do?

Answer: This behavior can have several causes. First check the focus and make sure it is in the recommended area. An incorrectly aligned motor axis (side draw/strap) can also lead to problems when starting. At the start of unmounted slopes, an easy lifting of the rear wheel can also help to achieve sufficient speed for controlled lifting.

Question: How can I improve land properties?

Answer: The installation and use of the optional flaps considerably improves the landing properties. They allow for a steeper approach path while at the same time reducing speed. Make sure to keep a little more engine power when the flaps are extended in order to avoid sagging. A light head load can also contribute to more stable landing approaches.

Question: My model has structural damage after a hard impact. How can I fix this?

Answer: Smaller damage to the balsa wood structure can be repaired with wood glue, possibly reinforced by balsa wood strips. If the wiring is damaged, an iron can help to close smaller cracks at a low level. For greater damage to the covering, appropriate UltraCote patches should be used in matching color. In the case of structural damage to supporting parts such as the wing connecting tube, an exchange of the components concerned is advisable.

Question: Can I also run the Piper Pacer with a 4S battery?

Answer: In principle, conversion to 4S is possible, but requires adjustments. The ESC must be suitable for 4S, and the propeller should be adjusted (small diameter/strength). The significantly higher performance can change the flight characteristics and places higher requirements on the structure. The 3S configuration recommended by the manufacturer is recommended for beginners.

Question: How winterproof is the model?

Answer: The UltraCote tension is relatively insensitive to moisture, but the model should be exposed to no longer wet. Low-temperature flights are possible, but can affect battery performance. After flights under moist conditions, the model should be thoroughly dried to avoid damage to the wood structure.
