Technical data and facts

Customer reviews and experiences

Many users emphasize the enormous flight stability of the double decker, which, combined with the splashy motorization, allows both precise art flights and spectacular 3D maneuvers. Particularly positive:

• Flight behaviour & taxability: The e-flite ultimates are described as extremely precise and directly controllable. Pilots praise the large rudder surfaces and the high agility, allowing complex 3D figures such as torquen, hover or snap rolls.
• Assembly: The factory-side preassembly is a big plus. Many users report that the model is ready to fly within 30-60 minutes, as only areas, height and side control as well as the receiver and battery need to be installed.
• Processing: The quality of the material used (EPO rigid foam reinforced with carbon fiber) is frequently praised. The material is referred to as impact resistant, durable and yet light.
• Drive: Especially with 4S batteries, the performance is thrilling even experienced pilots. Tensile force, inclinability and acceleration are called “brutal” – perfect for dynamic 3D art flight.

Some critical voices note, however, that the model reacts sensitively due to the low weight of strong winds and that high rudder rudder rashes for beginners bring a certain potential for reconciliation.

Test results

Professional magazines and experienced pilots are impressed by the diverse flight modes, the controllable engine power (depending on battery) and the robust electrical system. In the practical test the double-decker convinces with:

• Powerful and responsive brushless drive
• Direct linking through non-playing metal transmission servos
• Easy handling during installation and removal (tool-free surface mounting)
• Various telemetry functions with compatible spectrum transmitters (e.g. monitoring battery status, temperature, etc.)
• Excellent relationship between flight stability and maneuverability

Comparative tests show that this model in its price segment is one of the most powerful and modern solutions for advanced art flight and 3D maneuvers.

Material quality

In the E-flite Ultimate 3D 950mm, a combination of light EPO rigid foam and targeted carbon fiber reinforcements was set. This gives the model a high crash resistance and the necessary torsional stiffness for extreme flight maneuvers. Even after several unsustainable landings, many users report about low to no structural damage. The coating is UV-resistant and cleanly applied from work.

Flight times

The flight time depends heavily on the battery used and the flight mode:

• With 3S 2200mAh: 6–8 minutes with moderate mix of art flight and normal flight.
• With 4S 2200–2700mAh: 4–7 minutes, with intensive 3D maneuvers rather shorter, in classic art flight operation and with economical gas control, however, quite 7 minutes and more possible.

Pilots report that electronics and controllers remain cool even in longer flights, which indicates an efficient design.

Increased power

With the use of 4S-LiPo packs, the double decker achieves an impressive vertical gradient. Many pilots use terms such as “sensual walking away from the stand” or “unlimited climbing ability”, meaning that the model can be accelerated and maintained vertically without losing a ride.

Transport capacity

Thanks to the clever quick release system, support surfaces and guides can be disassembled without tools. The model can also be found in smaller cars. Important aspects of transportability:

• Stable carbon hull and reinforced surfaces prevent deformation during normal transport.
• The low weight simplifies handling.
• For travel, however, a padding is recommended to avoid dents in the EPO foam.

Spare parts supply

E-flite is known for a very good spare part supply. Almost every item, from the bonnet, surface halves to small parts such as suspensions or rudder horns, is available as a spare part. Sales are carried out via many dealers in Europe, which guarantees short delivery times. Components such as motors, controllers and servos are also individually re-adjustable.

Target group

The Ultimate is suitable for advanced RC pilots who already have experience with art flight models and want to fly 3D maneuvers. But also experienced sports pilots looking for an agile double-decker for precise art flight are addressed. For beginners, the model is less suitable due to the high maneuverability and rudder deflections, unless one “damps” the control paths first strongly over dual rate/expo.

Construction time and instructions

Thanks to the high prefabrication, assembly is easy and quickly done. The guide is clear, well illustrated and multilingual. The structure rarely lasts longer than an hour. Important features:

• Clear step-by-step guide
• Photos and drawings for each step
• Notes on the focus position and correct installation of the receiver
• Important tips for battery and receiver cable management

Community support

The Ultimate has a wide fan community with active online communities in numerous forums. Social networks also offer numerous experience reports, setups and tips. Especially the exchange of settings (Expo/Dual Rate, Focus, Drive Variants) is helpful for new owners.

Alternative products of competitors

The E-flite Ultimate 3D 950mm stands out positively thanks to its modern electronics (Smart ESC, Telemetry), toolless assembly and high spare parts availability. Many competition products offer only standard controllers, less precise rudder deflections or less variety of spare parts.

Value for money

In view of the high-quality components, very high prefabrication, innovative drive technology (Smart ESC with telemetry) and the flexible battery setup, the Ultimate offers a very good value for money. While cheaper models often bring only standard technology and less robust servos, the E-flite model is all designed for longevity and performance.

Tips, tricks, recommendations, optimizations

• Expo & Dual Rate: Beginners should take the rudder rudders at a dual rate for the first flight to approx. Limit 60–70 % and program Expo values from 30–40 % to side and height rows. The model remains in the neutral position, but reacts agile in the extreme range.
• Battery choice: A 4S LiPo with 2200–2700mAh is recommended for maximum 3D fun. If you want to fly longer, use 3S batteries and moderate gas management.
• Priority: The focus recommended by the manufacturer is well chosen for most art flight figures. For very slow torquen, the SP can be moved slightly backwards.
• Rudder steering: Before the first flight, check the ball heads of the articulations and give a drop of screw securing to the thread if necessary.
• Landing: Despite the high engine power, the model is good at landing. A light gas when placed prevents tilting.
• Spare parts: For frequent flyers it is recommended to order a replacement suspension and propeller on stock at the dealer.
• Use telemetry: With compatible spectrum transmitters, you can monitor battery and ESC data in real time – a real security boost!

What could buyers still be interested in?

• Compatibility: The PNP version requires its own receiver and transmitter (min. 4-channel). 7-channel transmitters are required for telemetry and motor reversal.
• Weather suitability: Fly under 15 km/h due to the light EPO construction. With stronger wind, the model becomes more difficult to control.
• Application: Perfect for clubs, larger meadows or model airfields – for the small city park the double decker is too strong.
• Noise development: Compared to burner models quiet but audible with full gas.
