Test results and performance analysis

In various tests, the E-flite Jet convinces with excellent performance values:

Speed and acceleration

With a 6S 4000mAh battery, maximum speeds of over 160 km/h were measured. Acceleration takes place linearly and powerfully, without unwanted flight property changes at higher speeds.

Increased power

The vertical performance is impressive - the model can rise almost indefinitely vertically until visibility becomes a limiting factor. Tests show a vertical climb of over 100 meters from the stand.

Handling and maneuverability

The digital metal transmission servos provide precise control commands. The model reacts directly to inputs, but remains easily controllable even at lower speeds. Advanced maneuvers such as rollers, loopings and knife flight are easily possible.

Stability and wind sensitivity

In tests, it was found that the jet flies stable even in light to medium winds. The aerodynamic shape and the balanced weight ensure good wind stability, while beginners should be careful with stronger winds.

Material quality and processing

The processing of the PNP model shows the typical E-flite quality. The EPO foam is provided with composite reinforcements at strategic points, which gives the model additional strength. The coating in the Thunderbirds design is precisely applied and also smaller details are clean.

Particular mention should be made of:

• Robust connections: The truncated surface connection is stable and easy to assemble.
• Quality service: The pre-installed digital metal transmission servos provide precise control and long service life.
• High-quality suspension: The electrically retractable suspension with shock-absorbing struts allows start and landings on various subsurfaces including short grass.

A potential weak point could be the bug suspension mechanism, which can take most damage in harder landings. Experienced users recommend special care in the first landing attempts.

Flight times and battery management

With a recommended 6S 3200-4000mAh LiPo battery, realistic flight times of 4-6 minutes are possible with full power utilization. With moderate flight style, up to 7-8 minutes can be achieved. The actual flight time depends heavily on the flight style:

• Continuous high-speed flights reduce flight time to about 4 minutes
• Mixed flight profiles with moderate speeds and occasional full gas phases allow about 5-6 minutes
• Preserving flying style with a few full gas passages can allow up to 8 minutes

Experienced pilots recommend the acquisition of several batteries in order to be able to optimally use the time at the flight field. The built-in 85A ESC offers sufficient power reserves for the recommended battery sizes and ensures efficient energy management.

Transport capacity

With a span of 815mm, the Thunderbirds Jet is relatively compact for an EDF of this performance class. The transport capacity is as follows:

• Dismantling: The supporting surfaces can be easily separated from the hull, whereby the model fits in common transport boxes or special model carrying bags.
• Protection: For transport, a padded bag or box is recommended to protect the detailed surface.
• Preparatory period: The model is ready for flight in about 5-10 minutes, as the support surfaces must be mounted and the battery must be used.

For frequent transports it is worth investing in a special model carrying bag with foam inserts that protects the model safely from transport damage.

Spare parts supply

Tips, tricks and optimizations

Performance optimization

1. Battery selection: High-quality 6S 4000mAh 30C+ LiPos are recommended for maximum performance. Brands such as spectrum, Tattu or GensAce have proven themselves.

2. Priority optimization: A slight rearward shift of the center of gravity (1-2mm) can increase agility – but recommended only for experienced pilots.

3. Servo optimization: Eliminating play in the distractions by precisely adjusting the fork heads improves control accuracy.

4. Impeller tuning: Careful checking and, if necessary, easy reworking of the Impeller inlet nozzle can increase efficiency.

Flight practice

1. Start technique: For optimal launches, accelerate the jet with slightly pulled uphill and let it gently lift at about 60% of the maximum speed.

2. Land engineering: A longer landing approach phase with moderate sinking leads to more controlled landings. At about 30% gas, the sink rate is controlled by metered high-rise powder.

3. Speed management: At high speeds, smaller rudder rudders are more effective and gentler for the servos.

4. Battery management: To maximize battery life, you should leave about 20% residual capacity and not fly to the LVC (Low Voltage Cutoff).

Improving durability

1. Strengthening critical positions: An additional reinforcement of the chassis shaft with thin plywood or GFK can increase longevity.

2. Cable management: Careful laying and securing of cables prevents damage and short circuits.

3. Protective films: Transparent protective film at particularly endangered areas (bottom underside, wing edges) reduces wear and damage.

4. suspension protection: A slightly resilient landing on the main suspension with a later lowering of the bow suspension protects the mechanics.

Frequent questions and problem solutions

Question: How does the PNP version differ from the BNF version?

Answer: The PNP version (Plug-N-Play) of the F-16 Thunderbird comes without a receiver and has to be equipped with a compatible receiver of your choice. The BNF version (Bind-N-Fly) already contains a pre-installed spectrum of AR631 receivers with AS3X and SAFE Select technology. PNP requires more setup work, but offers flexibility in the choice of the remote control system.

Question: My jet has stability problems at high speed. What can I do?

Answer: First check the focus – it should exactly match the instructions. Reduce the rudder beats for high and high speed (dual rate setting). Make sure there are no aerodynamic irregularities (bended rudder, asymmetrical settings). The BNF version can also help to adjust the AS3X amplification values.

Question: How can I extend the flight time?

Answer: Efficient flying with less solid gas phases, utilization of thermal upcoming and a more conservative flight style can significantly extend the flight time. The use of 6S 4000mAh batteries with higher capacity also offers more flight time. Take care of an optimal Impeller spalt and clean, aerodynamic surfaces for maximum efficiency.

Question: Does an upgrade of the engine or ESC make sense?

Answer: The factory-built 3060-1900Kv engine and the 85A ESC are already well matched and offer sufficient performance. An upgrade rarely brings significant improvements and can affect the balanced flight behavior. High-quality batteries and well maintained standard components are more sensible.

Question: The retraction suspension works unreliable. What can I do?

Answer: Check the power supply and cable connections to the chassis. Clean the chassis shafts of dirt and dust. Make sure that the mechanism is smooth and no cables are clamped. In case of ongoing problems, a service of the suspension or in the extreme case a replacement of the suspension unit may be necessary.

Question: Can I fly the jet without a landing gear?

Answer: Hand starts are possible, but require experience and ideally a helper due to the high thrust force. For landings without suspension, a smooth, grassy area should be chosen. In the long term, flying without suspension is not recommended, however, as the fuselage can take damage and the balance of the aircraft is impaired.
