Technical data and specifications at a glance

Before we dive into the details, here the most important technical data of the micro-customer in clear form:

Equipment and special features

The compact Thunderbolt II replica features several outstanding features that make it a coveted model for hobby pilots. The combination of powerful drive and AS3X stabilization technology gives the small jet an impressive flight behavior.

Drive system and power

The heart of the UMX A-10 form two 28mm Impellers powered by powerful 13.500Kv brushless engines. This combination ensures impressive speed and climbing performance. The drive system is remarkably efficient and allows flight times of 5-7 minutes with the recommended 800mAh 2S LiPo battery.

The double ampellers give the model not only an authentic appearance, but also a realistic flight performance. The thrust is enough to perform dynamic flight maneuvers without the model hitting its limits. The lightweight design combined with the engine power allows agile flight behavior that will inspire even demanding pilots.

AS3X Stabilization Technology

An outstanding feature of Micro-Warthogs is integrated AS3X technology. This works in the background to minimize the effects of wind and turbulence. The result is a feeling of stability and precision that gives the impression of flying a significantly larger jet.

AS3X technology is particularly advantageous for pilots who dare to transition to EDF jets. It ensures predictable flight behaviour and makes the model also accessible to mid-level pilots without impairing the dynamics and fun for experienced pilots.

Controllability and flight characteristics

The UMX A-10 has full 4-channel control with functional double-side rows. These provide sufficient side rudder authority for impressive blade flight maneuvers. Despite its considerable contemplation, the model does not have any treacherous demolition properties or problematic slow flight behaviour, which makes it accessible to less experienced RC pilots.

The model has a removable suspension with a steerable boom that allows realistic rolling and starting. Pilots, however, also have the option of removing the suspension in order to reduce air resistance and to further optimize flight behavior.

Scale details and appearance

For many enthusiasts, the true scale appearance is just as important as the flight performance. The E-flite UMX A-10 also shines in this area with impressive details:

• Original silhouette of the A-10 Thunderbolt II "Warthog"
• Clear cabin hood with pilot figure
• Detailed replica of the notorious GAU-8/A Avenger Kanone
• Authentic panel lines and surface details
• Rare "Flipper" camouflage scheme in two-colored grey

While the model is sufficiently robust for normal flight situations, beginners should remember that it is a lightweight foam model. Hard landings or crashes can cause damage. Fortunately, most damages can be easily repaired with commercial foam adhesive.

The electronic components such as motors, servos and the receiver are of good quality and are sufficiently dimensioned for the intended purpose of use. For normal use, a long service life is to be expected.

Flight time, climbing performance and transportability

Flight time

With the recommended 800mAh 2S LiPo battery, the UMX A-10 reaches flight times of 5-7 minutes, depending on the flight style. This time span is quite typical for EDF jets of this size class, as the high-performance engines have a relatively high power consumption.

To maximize flight time, recommend experienced pilots:

• Not constantly flying with full gas
• Gentle, wide curves to fly instead of energy-consuming narrow turns
• Multiple batteries for consecutive flights
• Use full capacity of high quality 2S LiPo batteries with 800mAh

Increased power

The gradient of the compact jet is impressive. The two 13,500Kv engines provide enough thrust to perform steep climbs. After the start, the model quickly reaches height and can easily complete several successive loopings or other vertical maneuvers without losing at the moment.

The good climbing power makes the jet also suitable for low-level airfields, as it can quickly reach a safe altitude.

Transport capacity

One of the great advantages of UMX format is the excellent transport capability. With a span of only 562 mm, the A-10 fits easily in commercial transport boxes or special model aircraft bags. The removable suspension additionally facilitates transport and reduces the risk of damage.

The low weight and compact dimensions make this jet an ideal companion for model flyers who often want to take their aircraft to different airfields.
