E-flite UMX Citation Longitude Twin 30mm EDF Jet: Detailed guide for buyers

The E-flite UMX Citation Longitude Twin 30mm EDF Jet BNF Basic with AS3X and SAFE Select (EFLU6350) has been thrilling with a unique combination of impressive technology, practical handling and excellent flight characteristics since its launch. Anyone interested in a model in this class will find a structured, comprehensive overview of all aspects of this advanced Ultra Micro-Jets.

Technical data & facts in the overview

Customer Reviews & Experiences

Satisfaction and highlights:Buyers regularly praise the high stability of the model in the air. Thanks to AS3X technology, turbulence is effectively balanced, the model also lies with wind “like a board” and conveys a significantly greater feeling of flight. The SAFE Select function offers especially beginners an excellent protection against control errors by using automatic self-leveling and slope limitations.

Critical points:Individual users report that access to the battery can be a bit tricky. In addition, the enclosed wheels for grass landings could be too small. However, the suspension can be simply removed, which allows spontaneous adjustments.

Experiences in everyday life:The flight properties in the lower speed range are consistently positively evaluated, as are the very precise control commands. For transport, reference is made to the compactness and robustness of the EPO foam – small remplers or land damages are usually without follow.

Test results and flight practice

Flight stability:
In test reports, the jet convinces above all with its authentic, scalable appearance and the “locked-in” performance, as you otherwise only know from larger models – not least thanks to AS3X and the optimized aerodynamics.

Performance:
The 2x 8800Kv Brushless-Outrunners deliver impressive propulsion. The model is designed for 3S operation, which ensures strong thrust and acrobatic pitch angles. Vertical climbing flights as well as fast over flights are easily possible.

Flight times:
With a recommended 3S 800 mAh LiPo, an average of 4–6 minutes flight time is reached, depending on the flight style. Saving flies and glide phases can extend the time to over 7 minutes.

Material quality

The Ultra Micro Jet consists of EPO high density foam, which is considered particularly light, stable and easy to repair. Paint and stickers underline the scale look. The foam absorbs small impacts well and can easily be repaired with second glue if required.

Transport capacity

With a length of about 63 cm and a weight below 250 g, the model fits into any backpack or trunk. The suspension can be removed without tools, so that the model is ready for transport in no time.

Spare parts supply

E-flite is known for reliable replacement and accessory logistics. Replacement wings, hulls, servos and impellers are readily available in online trade. Due to the modular design, damaged parts can also be easily replaced by less experienced model builders.

Target group

The Citation Longitude is aimed at advanced pilots as well as ambitious starters who already have basic knowledge in flying cross-ruder models and ampeller models. The SAFE Select function helps pilots with a little less experience to find a quick and secure entry into the EDF class.

Construction & Guidance

Installation time:
The model comes almost fully assembled from the box. Only the chassis and the attachment of the supporting surfaces are required. Pure setup time: approx. 5–10 minutes.

Instruction:
The user manual is written as clearly structured, richly illustrated and understandable. Step-by-step all necessary handles are described – also for the first flight with SAFE Select.

Community support

An international fan community has developed around the model. If you have any questions, find detailed tips and flight videos in relevant forums such as RC Groups, Facebook Groups or YouTube. Also manufacturers and dealers offer a competent direct support as well as video leads.

In comparison, the E-flite UMX-Jets convince with the best combination of compact size, stability and modern flight stabilization.

Value for money

The price for this model is in the middle to upper segment of the Ultra Micro-EDF class. Taking into account the high-performance double drive, the high-quality components and the innovative technology (AS3X/SAFE), there is a very solid price-performance ratio.

Tips, tricks, recommendations & optimizations

• Battery choice: Use high quality 3S 800mAh LiPo batteries to get the maximum flight time and performance out. Alternatively, a somewhat larger battery (with little weight increase) can also be sampled for longer flights.
• Propeller balance: The EDF-Impellers are already running round. If you want maximum smoothness, you can also balance it.
• Landing: For bumpy substrates it is recommended to disassemble the chassis and to perform sliding landings.
• Flight modes: Use SAFE Select at the beginning – later the AS3X-only function can be activated in the flight to enjoy art flight and higher agility.
• Repairs: Smaller fractures in the EPO foam can be repaired with second glue and activator spray.
• Transport: Use a protective cover or transport box to protect the model from impacts and UV radiation.

Questions and problems of users – and their solutions

1. The model does not react to the transmitter – what to do?Check if the transmitter is compatible with DSMX/DSM2 and the binding process has been performed correctly. Doesn't help check battery charge and plug.

Two. Flight times seem too short – why?In most cases, too small a battery is used or flowed too aggressively. With a fresh 800 mAh battery and sliding flight style, up to 7 minutes are possible.

3. The model tilts easily when starting – what is it?Here a focus control (CG) helps according to instructions. Possibly, the rear weight is too high (accus too far behind).

4. SAFE Select cannot be deactivated – how is it?SAFE Select can be switched on and off at the transmitter via a separate channel. Note instructions and if necessary re-binding.

Five. Spare parts are sold out – alternatives?E-flite offers spare parts lists on the manufacturer's side and in trade. Alternatively, minor damage to the foam can also be repaired.

6. Model to flott for beginners?By SAFE Select and moderate control commands, if necessary Expo, the agility can be drawn – ideal for ambitious beginners.

7. How can I upgrade the LEDs?The standard navigation lights can be exchanged for stronger LEDs or further modules can be retrofitted. There are special kits here.

What buyers should know

• Scale authenticity: The jet is officially licensed by Cessna, reflecting in details such as decor, hull design and lighting.
• Upgrade potential: Anyone who wants even more individuality can retrofit with Airbrush, Decals or additional lighting elements.
• Flight experience: Despite ultra-micro format, the model brings real jet feeling for small pitches, sports pitches or even larger gymnasiums – and also for many employees, thanks to a short preparation time.
• Weather resistance: Thanks to AS3X technology and model size, flights are also safe in light wind – unlike many other micro-Jets.
• Comprehensive documentation: Supporting videos, online communities and active producer channels provide competent assistance for all questions.
