The ultimate purchasing advice for the E-flite Twin Otter 1.2m model - The versatile STOL aircraft in detail

As a versatile and user-friendly RC aircraft, the E-flite Twin Otter 1.2m BNF Basic with AS3X and SAFE, includes Floats (EFL30050) has made a name in the model flying scene. This true-scale replica model of the legendary bushplane offers advanced pilots an authentic flight experience with numerous functions. In this comprehensive guide we illuminate all aspects of this popular model, from technical data to customer experience to practical tips for optimal operation.

Technical specifications and equipment

The Twin Otter from E-flite is an impressive model aircraft with high-quality functionality. Here you can find all important technical data at a glance:

The model aircraft comes with pre-installed components and requires only a compatible transmitter, aeroplane battery and charger to be ready for use. A special feature of this two-engine model is the included float set that allows water operations and reflects the versatility of the original.

Flight characteristics and performance profile

Flight time and range

With a recommended 3S LiPo battery between 2200 and 3200 mAh, the Twin Otter model reaches flight times between 7-12 minutes, depending on flight style and battery capacity. With moderate flight style and optimal conditions, experienced pilots can also achieve longer flight times. The efficient aerodynamics of the aircraft and the two brushless engines ensure a good balance between performance and energy consumption.

Increased power and maneuverability

The Twin Otter convinces with its STOL capability (Short Take-Off and Landing), which is based on the original. Thanks to the two powerful 2210Kv engines, the climbing power is impressive, even with an installed float. Pilots report a stable climb and good control even in adverse weather conditions, which is due to the built-in AS3X system.

The flight behaviour is predictable and good-natured, which gives the model a certain beginners friendliness despite its classification for advanced pilots. SAFE technology offers additional stabilization and can be very helpful in emergency situations.

Material quality and processing

The E-flite Twin Otter uses high-quality EPO foam components that are both lightweight and resistant. The quality of the processing is consistently positively evaluated by users, in particular the faithfulness of the scale reproduction is recognized. The pre-installed components such as motors, servos and electronics are carefully installed and well secured.

The surface of the model is provided on the factory with a detailed painting, which is according to the original airliner. The LED lighting not only increases the optics, but also improves visibility in flights in the dusk.

Customer experiences and reviews

Positive feedback

Pilots with experience in the RC-Hobby particularly appreciate the versatility of the model. The possibility of starting both land and water thanks to the supplied swimmers is called a big plus point. Many users praise the flight properties as "determined" and "realistic", which gives the model a special authenticity.

The pre-installed AS3X technology consistently receives positive evaluations as it effectively balances wind blows and ensures stable flight behavior. The SAFE technology is also estimated as a useful security feature, especially by pilots flying a two-engine model for the first time.

Critical votes

A few customers complain about the susceptibility of the bottom of the hull when landings on rough ground. Here it is often recommended to add additional reinforcements. There are some reports on the need to readjust the rudder steering after prolonged use.

In the case of the swimmers it was noted by some users that the assembly can be a bit tricky and an additional seal for longer water inserts is recommended.

Test results and expert opinions

The E-flite Twin Otter model has been extensively tested in various specialist magazines and online platforms for RC model construction. The reviews are mostly positive, with special praise for:

• The authentic flight performance that comes very close to the original airliner
• The high-quality processing and detail accuracy
• The good suitability for everyday use and different flight conditions
• Flexibility through the included float kit

Experts stress that the model offers an excellent balance between scale and flight performance. A recurring topic in test reports is user-friendliness despite the classification for advanced pilots.

Transport and handling

Transport capacity

The Twin Otter 1.2m is still relatively good to transport with its span of 1.2 meters. The structure is designed in such a way that no complicated disassembly is necessary for transport. However, the support surfaces can be removed with few handles as required, which facilitates transport in smaller vehicles.

For safe transport, experienced users recommend special foam holders or customised transport bags to avoid damage. The floats can be transported separately, which offers additional flexibility.

Construction and preparation

A great advantage of the BNF-Basic concept (Bind-N-Fly) is the minimal assembly effort. The Twin Otters are pre-assembled so that only a few steps are necessary before the first flight can take place. Typically, the assembly is limited to:

1. Mounting of the supporting surfaces on the fuselage
2. Binding of the receiver with the transmitter
3. Creating and securing the flight battery
4. Optional installation of floats (if water start is planned)

The attached guide is described by users as clear and understandable, with helpful illustrations for each step. The total duration for the initial preparation is about 30-45 minutes, and the time is reduced to a few minutes for subsequent use.

For starters, the price may initially appear high, but the pre-installed components save time and potential sources of errors during assembly, which justify the investment in the long term.

Tips, tricks and optimizations

Flight optimizations

Experienced Twin Otter pilots recommend the following optimizations for an improved flight experience:

1. Priority optimization: Easily adapting the centre of gravity according to personal preference can affect flight behaviour noticeably.

2. Rudder: fine tuning of the rudder rudder rudders according to their own flight style - lower deflections for true-scale flying, larger for acrobatic maneuver.

3. Battery positioning: Experiment with the exact position of the flight battery to optimize focus without additional weight.

4. landing flap adjustment: Adjust the landing flaps for more realistic start and landings.

Technical improvements

For technically experienced pilots there are various ways to optimize the Twin Otter:

1. Reinforcement of the hull bottom: Mounting thin GRP material or adhesive tape at particularly stressed locations.

2. Improved LED lighting: In addition to factory lighting with additional LEDs for increased visibility and scale optics.

3. Optimized floats: Additional waterproofing of floats for longer water inserts.

4. Improved distractions: Exchange of standard deflections against high-quality metal or carbon variants for more precise control.

5. Additional telemetry: Integration of telemetry sensors for real-time flight data such as speed, height and battery voltage.
