User Experiences and Reviews

The feedback from the pilots to the small VTOL aircraft is predominantly positive. The versatility of the model, which can be flown both indoors and outdoors, is particularly appreciated. The compact size makes it an ideal companion for model flyers that do not have large airfields available.

Customer reviews for different aspects

Many users report an amazingly stable flight performance in multicopter mode. The transition to the surface flight is described as smooth, whereby the automatic operation works reliably. Some pilots indicate that they needed a certain reconciliation time in the first flights, especially if they had no experience with VTOL aircraft beforehand.

A recurring praise applies to the robustness of the EPO material from which the hull is made. With smaller crashes, the model shows hardly any damage, which makes it particularly attractive for advanced beginners who do not yet have perfect landing skills.

The control software of the Delta-Flügel-VTOL is praised for its ease of use. The setup of the transmitter is much simpler than with many comparable VTOL models, since no complex programming is required.

Test results and flight performance

In extensive tests, the compact swivel motor aircraft has demonstrated its versatility. Flight services can be evaluated in different categories:

Flight time and range

With a recommended 3S 800mAh LiPo battery, the model reaches flight times of about 6-8 minutes. This varies according to flight style and environmental conditions. In the pure fly mode, the flight time is somewhat shorter than in the plane flight mode where the aerodynamics of the delta wing comes to bear.

Increased power and agility

The gradient of the small VTOL exceeds the expectations of many testers. With three powerful brushless motors, the model is quickly and controlled in multicopter mode. In surface flight mode, the engine power also allows impressive climbing flights and even acrobatic maneuvers.

In Acro mode, the flight model shows its sporty side with considerable difficulty. Loopings, rollers and other art flight figures are easily possible, which is not obvious for a VTOL model of this size class.

Stability in different weather conditions

The integrated flight stabilizer ensures a quiet flight in the Stability mode, even with light wind. In the case of stronger winches, the 410mm span and the light weight however reach their limits. For outdoor flights experienced pilots therefore recommend windless or only slightly moving air days.

Material quality and processing

The processing of the model aircraft is generally described as high quality. The EPO foam is light, yet robust enough to forgive smaller flight errors. The movable parts, in particular the pivoting mechanisms of the vane motors, are precisely manufactured and function reliably even after numerous flights.

The brushless motors provide sufficient power for dynamic flying and are characterized by good smooth running. The pre-installed controllers operate efficiently and ensure good energy utilization of the battery.

Transport and storage

Thanks to its compact dimensions, the mini-VTOL is particularly transport-friendly. It fits in most models and does not require disassembly for transport. This is an important advantage over larger models that often have to be disassembled.

For storage, users recommend a dry environment to maximize the service life of electronics. As with all LiPo-operated models, the battery should always be kept separately and in storage (about 3.8V per cell).

Spare parts supply and maintenance

The spare part availability for the E-flite model is rated as good by most users. By belonging to the Horizon Hobby Group, there is a wide dealer network that provides spare parts. Replacement propellers are particularly important, since they can be most damaged in soil contact.

Maintenance of the swivel wing VTOL is uncomplicated. Regular controls of hinges and motor bearings as well as cleaning after dusty flights are recommended to maximize service life.

Target group and entry barriers

The Mini Convergence VTOL is aimed at several target groups:

  • Advanced beginners looking for entry into VTOL technology
  • Experienced pilots who need a compact model for limited flight spaces
  • FPV enthusiasts looking for an alternative flight platform
  • Technique enthusiasts who want to combine the best of multicopters and aircraft

As a PNP version (Plug-and-Play), the model is already largely pre-assembled. Only a few steps are necessary for assembly, which facilitates entry. The assembly time is about 30-45 minutes, whereby the receiver must be installed and the control must be set up.

The accompanying guide will be described as understandable and detailed. It contains detailed illustrations and tips for the correct setting of the controller.

Community support and resources

An active community has developed around the Delta-VTOL. In forums such as RCGroups there are numerous discussions on optimizations and experience reports. YouTube videos demonstrate flight techniques and provide valuable information on configuration.

Horizon Hobby, the sales partner of E-flite, also offers a comprehensive customer support that supports technical problems. This is especially helpful for newcomers in VTOL technology.

Comparison with alternative products

In the segment of compact VTOL aircraft, there are some alternatives to consider buyers:

XCraft X PlusOne

This VTOL model offers a similar functionality, but is larger and more expensive. It is aimed primarily at professional users and offers longer flight times, but at the expense of entry-level friendliness.

Freewing Scorpion VTOL

As a direct competitor, the Scorpion offers a similar concept, but with four engines instead of three. This increases the stability in flight, but also makes the system more complex and susceptible to disturbances.

Eachine Vtail

A cheaper alternative with simpler flight system. The Vtail offers less features and a lower construction quality, but could be interesting for absolute beginners who want to test the VTOL concept first.

Compared to these alternatives, the Mini Convergence is positioned as a balanced compromise between entry-level, performance and price. In particular, the simple switching between the flight modes and the good processing results in comparison.

Value for money

With a market price in the middle segment, the compact swivel motor-VTOL offers a good price-performance ratio. The materials used and the pre-installed electronics justify the price, especially when considering the versatility of the model.

Compared to separate acquisitions of a multicopter and a surface aircraft, the combination model can even be considered as a cost-effective alternative. In addition, it must be taken into account that a compatible transmitter, receiver, battery and charger are still required for operation if not already present.

Tips, tricks and optimizations

After numerous flights with the Mini-VTOL, experienced pilots have developed valuable optimizations:

Performance upgrade through battery selection

Although the manufacturer recommends 3S 800mAh LiPos, some pilots report good experience with high quality 850mAh batteries that allow a somewhat longer flight time. It is important to pay attention to the weight because heavier batteries can negatively influence the flight properties.

Propeller optimization

The standard propellers deliver good results, but slightly modified propellers with optimized profile can increase efficiency. This is particularly noticeable by calmer flight behavior.

FPV extension

The model is prepared for FPV extensions. A light camera and a compact video transmitter can be easily integrated. Pilots recommend ultra-light components to prevent the performance of the flight.

Flight style tips

The following techniques have proven successful for optimal flight with the swivel rotor model:

  • Gentle transition from fly to forward flight through gradual tilting
  • avoid abrupt control movements during the transition phase
  • Use of the wind shadow for more efficient flight
  • Slow, controlled landing approaches in VTOL mode

Frequent questions and problem solutions

Based on user experience, questions and problems occasionally arise when using the compact VTOL:

"My model is shaking in flight. What can I do?"

This problem often occurs in vibrations. Check the propellers for damage and make sure that all engines are fixed. Calibration of the flight control can also help.

"The transition to the surface flight does not work reliably."

There are several possible causes for this:

  • Check the correct configuration of your transmitter
  • Make sure that the engines can swing freely
  • Calibration the tilt sensors
  • If necessary, update the firmware

"How can I extend the flight time?"

The flight time can be optimized by efficient flying:

  • Avoid frequent ascent and descent
