The ultimate guide to the Delta Pilot: E-flite Ultrix 600mm BNF Basic

Are you looking for a versatile RC aircraft that is suitable for both beginners and advanced pilots? The Ultrix 600mm from E-flite could be the right model for you. This comprehensive guide provides you with all the information you need to know as a buyer - from technical data to flight characteristics to tips and tricks for optimal operation.

Technical data and specifications

The E-flite Ultrix 600mm BNF Basic (EFL02250) is a larger version of the popular UMX Ultrix and convinces with its versatile flight characteristics in a robust delta configuration.

Flight characteristics and performance profile

The Delta flight model from E-flite surprises with flying characteristics that would not be trusted in its compact design. Thanks to the two powerful brushless motors, the flyer offers an exceptional boost weight ratio. This allows:

• Impressive maximum speed
• Almost unlimited climbing power
• Perfect hovern
• Differentiated thrust for complex maneuvers such as urriers and flat spinels
• Smooth sports flies
• Basic art flight maneuver
• Aggressive 3D flight maneuver

The AS3X technology works in the background and balances wind and turbulence, which gives the pilot the feeling of flying a significantly larger model. This makes the 600mm delta flyer significantly more windy than its smaller UMX brothers.

Target group and accessibility

The Ultrix 600mm is aimed at a wide audience:

For beginners: The optional SAFE Select technology creates a safe flight environment with automatic stabilization. This also allows less experienced pilots to fly the model relatively safely. The robust EPP design also forgives smaller errors and crashes.

For advanced: If you switch off the flight support systems, the compact Delta flyer turns into an agile flyer that offers experienced pilots almost unlimited possibilities. From precise sports flies to sophisticated 3D maneuvers everything is possible.

For changers: Pilots who want to change from the UMX Ultrix to a larger model will find a perfect development with familiar flight characteristics, but better visibility and wind stability.

Flight time and battery power

The flight time of the E-flite Ultrix 600mm BNF Basic depends significantly on the battery capacity and the flight style used:

• When using a 3S 800 mAh LiPo battery and moderate flight style: about 6-8 minutes
• With a 3S 850+ mAh LiPo battery: up to 10 minutes
• For intensive 3D flights or frequent solid gas phases: 4-6 minutes

The telemetry function displays the battery voltage during flight on compatible transmitters, which allows good control of the remaining flight time. The overvoltage protection (OCP) also stops the motors when the controller is overheated, which protects the electronics.

Material quality and durability

The Ultrix 600mm is made of extremely durable EPP material (Expanded Polypropylene), which makes it one of the most robust E-flite models. This design offers several advantages:

• High crash resistance
• Low susceptibility to damage when crashing
• Lightweight with simultaneously high stability
• Easy repairs with commercial adhesives possible

The components installed at the factory, such as servos, motors and receivers, are well protected and are of known spectrum/E-flite quality.

Transport and storage

The compact dimensions of the Delta Pilot make it an ideal companion for flight adventures:

• Fits in most medium size RC transport bags
• No need to assemble or dismantle (Ready-to-Fly design)
• Robust material minimizes transport damage
• Low weight (233g) for easy ride

A dry environment and removal of the battery are recommended for storage in order to maximize the service life of all components.

Commissioning and preparation

The commissioning of the BNF Basic model is very simple:

1. Unpacking the fully preassembled aircraft
2. Switch on transmitter and connect to receiver
3. Connect full 3S LiPo battery
4. Optional bug suspension for roll start mounting (if desired)
5. Check the focus and, if necessary, adjust by battery positioning

Since all components are already installed and set on the factory, the assembly is limited to a minimum. The multilingual guide also guides beginners through all necessary steps and contains important safety instructions as well as tips for setting up flight modes.

Frequent questions and problems of users

Question: Is the Ultrix 600mm suitable for absolute beginners?

Answer: With activated SAFE technology, the Delta flyer is also available for beginners, but prior flight experience with a simpler trainer model or simulator is recommended. The delta configuration reacts somewhat more directly than conventional models. An experienced flight instructor at first flight is ideal.

Question: How does the model react to wind?

Answer: Thanks to AS3X technology, the Ultrix 600mm can be flown well even with light to medium wind (up to about 15 km/h). The 600mm span makes it much more windy than the smaller UMX version. With stronger wind, however, the flight behaviour is becoming increasingly demanding.

Question: Which transmitters are compatible?

Answer: All spectrum DSMX/DSM2 compatible transmitters with at least 5 channels work. Spectrum AirWare transmitters are recommended for full telemetry functions, including: DX6e/8e, DX6 G2/G3, DX8 G2, DX9, NX6/8/10, iX12 and iX20.

Problem: Vibrations and Shaking in Flight

Solution: Common causes are unbalanced propellers or loose motor mounts. A careful checking and balancing of the propellers as well as securing all screw connections can fix the problem.

Problem: Uneven thrust of the two engines

Solution: This can be caused by contamination, damage or different wear of the motors. Calibration of the ESCs or in the extreme case of replacement of a motor may be necessary.

Problem: Rechargeable batteries quickly

Solution: In addition to using higher-capacity batteries, efficient flying should be considered. Avoid permanent solid gas phases and build sail passages. In addition, pay attention to damage to the propellers or increased motor resistances that can increase the power consumption.

Conclusion: For whom is the E-flite Ultrix 600mm BNF Basic?

E-flite's compact delta flyer is an exceptionally versatile RC flight model that is interesting for both ambitious beginners and experienced pilots. The combination of robust design, advanced electronics and surprising flying characteristics makes it an all-rounder that is hardly disappointed in a flying situation.

The ability to switch between gentle sports flies and aggressive 3D maneuvers is particularly noteworthy - a property that is rarely found in this price range and order. The optional SAFE technology also creates a gentle entry for less experienced pilots.

With the right care and handling, the E-flite Ultrix 600mm BNF Basic offers years of flight fun and grows thanks to its versatility with the skills of the pilot. A clear purchase recommendation for RC enthusiasts looking for a compact, robust and surprisingly powerful Delta aircraft.
