Test results and flight performance

In extensive tests, Twin Otter 1.2m has demonstrated its qualities under different conditions.

Flight services

The dual engine gives the model special flight characteristics:

• Starting power: Thanks to the two engines, the model will be lifted after a short starting distance, which corresponds to the original short starting behavior of the real Twin Otter.
• Increased power: With an impressive gradient power of estimated 3-4 m/s with full gas, the model can quickly gain height.
• Flight speed: The Twin Otter covers a wide range of speeds - from slow scale forward flights to fast passages.
• suitability for art flight: Although primarily designed as a scale model, basic art flight figures such as loopings, roles and turns are quite possible.

Flight properties with floats

With mounted floats, the flight behavior changes easily:

• water start: The Twin Otter slides cleanly over the water surface and reliably lifts at sufficient speed.
• Air resistance: The additional floats significantly increase the air resistance, which leads to a slightly lower maximum speed and shorter flight time.
• Landings on water: Water landings require some exercise, but succeed with the right technique gently and elegantly.

Material quality and processing

The EPO material used (Expanded polyolefin) for hull and wings offers a good balance between stability and weight. The processing of Twin Otter 1.2m is generally considered to be high quality, with the following features:

• Details: The scale details such as rivet lines, panel lines and surface structures are elaborate.
• Finishing: The factory-side color scheme is cleanly applied and resistant to light wear.
• Stability: Critical areas such as the motor carrier and the suspension are designed to be reinforced.

In intensive use, however, certain areas may be susceptible to damage:

• The connection between hull and swimmers needs special attention in frequent water starts
• The propeller tips can be damaged in hard landings or collisions
• The steering of the rows can loosen when used intensively

Battery life and flight times

With the recommended 3S LiPo battery in the range of 2200-3200 mAh, the following flight times can be achieved:

• Standard configuration without float: 8-10+ minutes with mixed flight style
• With mounted floats: 6-8 minutes due to higher air resistance
• With predominantly full-gas operation: 4-6 minutes

The actual flight time is strongly influenced by the individual flight style, the wind conditions and the age of the battery. For longer flight sessions it is recommended to purchase several batteries.

Transport and storage

The Twin Otter with its span of 1.2 meters provides moderate requirements for transportation and storage:

• Ready for transport: The supporting surfaces can be separated from the hull for transport, whereby the model can be transported in a medium-sized car.
• Required storage space: In the assembled state, the model requires a bearing surface of at least 1.3 x 1.0 meter.
• Transport protection: For safe transport, a padded bag or a special RC model case is recommended.

Larger challenges are transport with mounted floats, as they significantly increase the base area. Many pilots therefore transport the floats separately and assemble them only at the site of use.

Spare parts supply

The spare parts supply for the E-flite Twin Otter 1.2m PNP model is basically positive:

• Availability: Long wear parts such as propellers, motors and servos are readily available from specialist dealers.
• Original parts: E-flite offers an extensive range of original replacement parts for the Twin Otter.
• Compatibility: Many components are compatible with other models of the E-flite family.

The procurement of specific scale parts such as the LED lighting elements or the float struts that do not belong to the standard range of each dealer can be challenging.
