The ultimate purchasing advice: The E-flite UMX P-47 BL BNF Basic with AS3X in detail

As an enthusiastic model flight enthusiast or newcomers to the world of ultra-micro aircraft, the E-flite UMX P-47 BL BNF Basic with AS3X may be on your wish list. This true scale model of the legendary P-47 Thunderbolt Combat Aircraft from World War II offers an impressive flying experience in compact size. In this comprehensive article we illuminate all aspects of this Micro-Warbird to enable you to make a sound purchase decision.

Technical data and specifications

The Ultra-Micro P-47 Thunderbolt from E-flite combines historical design with state-of-the-art model flight technology. Here the most important technical data at a glance:

Detailed product description

The Thunderbolt model impresses with its detail and flight characteristics. The developers have placed great emphasis on an authentic replica of the historical model. The model is based on the Thunderbolt, which by Major Howard D. "Deacon" Hively the 334. Fighting squad was flown during World War II.

The realistic painting is complemented by numerous scale details such as a dummy engine, true-to-scale wheels and a characteristic four-sheet propeller. The model comes fully assembled and is ready for use immediately after binding with a compatible transmitter and charging a suitable battery.

The innovative AS3X stabilisation system, which, despite its small size, gives the model a flying behavior that recalls significantly larger models, is particularly important. The technology works like a gyroscope, but does not require an additional channel or cumbersome settings - it is ready to use directly.

Flight experience and performance

Flight behaviour

The compact Warbird convinces with excellent flight characteristics. The combination of the powerful brushless external rotor motor and the 2S LiPo battery system ensures an impressive dynamic. Thanks to the AS3X system, the model flies stable and precise even in light winds, which is particularly advantageous for beginners in the Warbird class.

The control takes place via four channels, wherein the steerable spider wheel facilitates handling on the ground. The suspension can be easily removed for abdominal landings on grass surfaces, which underlines the versatility of the model.

Flight services

The UMX P-47 model offers impressive flight performances for a size class aircraft:

• Flight time: Depending on the battery used (200-280 mAh) and flight style, flight times of 4-6 minutes are realistic
• Speed: Thanks to the 2500Kv engine, the model reaches a considerable speed
• Art skills: The model dominates all art flight maneuvers of the original aircraft
• Wind suitability: With AS3X system easily accessible even with light wind

The model shows its strengths especially in free flight without suspension, where the aerodynamic properties are fully applicable and the optics are best effective.

Customer experiences and reviews

Positive feedback

Pilots who have already gained experience with the Micro-Warbird praise especially:

• The outstanding detail and true to scale optics
• The surprisingly good flying properties despite the compact size
• The AS3X system that ensures stable flight behavior
• Easy handling and quick readiness
• The possibility to remove the suspension for different flight conditions

Critical aspects

Some users point to the following aspects:

• The comparatively short flight time of 4-6 minutes
• Restricted flight performance in wind despite AS3X system
• The sensitivity of small servos in hard landings
• Higher purchase costs compared to brush-driven models

Target group and scope

The E-flite UMX P-47 Thunderbolt model is aimed primarily at:

• Advanced beginners who have already gained experience with basic models
• Experienced RC pilots looking for a compact Warbird for smaller flight fields
• Collector of historical aircraft models interested in flying exhibits
• Model semi-trailers with limited space for transport and storage

Due to the use of a brushless motor and AS3X technology, the model is more beginner-friendly than comparable Warbirds without these features, yet absolute newcomers should first gain experiences with simpler models.

Transport and handling

An important advantage of the Ultra Micro format is the excellent transport capability. The compact model can be easily transported in a special transport box or even in a correspondingly padded bag. With detachable suspension and without fragile external components, the model is ideal for model flyers who often take their aircraft to different airfields.

Spare parts supply and support

As a product of Horizon Hobby, the small Warbird enjoys a very good spare part supply. All relevant components are available from the manufacturer's shop as well as specialized model building dealers:

• Replacement servos (2.3 grams linear long-throw)
• BL180 Brushless Outrunner Motor (2500Kv)
• Recipient/ESC unit
• Propellers and spiders
• Structure parts and small parts

The availability of spare parts is an important factor for the longevity of the model, as in small aircraft of this type, despite careful handling, occasional repairs can occur.

Tips and tricks for optimal operation

Battery optimisation

To maximize flight time, recommend experienced pilots:

1. Use of high quality 2S LiPo batteries with 280 mAh capacity
2. Correct balance charging of batteries for maximum power
3. Keep multiple batteries ready for longer flight sessions
4. Rechargeable batteries not completely (respect low discharge protection)

Flight optimization

For the best flight experience with the UMX Thunderbolt you should note:

• For maximum performance remove the suspension under suitable landing conditions
• When wind always start against the wind and land
• Use gentle control movements to optimally use AS3X technology
• Regular checking of the rudder deflections and, where appropriate, Adaptation via remote control

Maintenance and maintenance

The correct care significantly extends the service life:

• Check the model for damage after every day of flight
• Remove batteries and store separately
• Remove dust and dirt carefully with compressed air
• Smaller damage immediately repair with suitable glue
• Check engine regularly for foreign bodies and correct function

Alternatives and competitive products

In the Ultra Micro-Warbirds segment there are some interesting alternatives to the E-flite P-47 model:

UMX Spitfire by E-flite

• Similar size and technology
• Characteristic Spitfire design
• Comparable flight characteristics with AS3X system
• A little lower weight, resulting in potentially longer flight time

UMX P-51 Mustang by E-flite

• iconic mustang design
• Similar technical base
• Easily different flight characteristics due to different aerodynamics
• Comparative price and equipment

FMS Mini Warbirds

• slightly larger models (800-900mm span)
• Often without AS3X system
• Partially cheaper purchase costs
• Mostly equipped with brush motors

In a direct comparison, the UMX P-47 model stands out due to its combination of brushless drive, AS3X technology and true-to-scale optics, but also justifys its higher price compared to simpler alternatives.

Value for money

The Thunderbolt in Ultra Micro format is positioned in the middle to top price segment for models of this size class. The investment is justified by:

• High-quality brushless drive
• AS3X stabilisation system
• Detailed execution
