DJI Insipre 1 Pro, double controller version, with DJI’s Focus, with zoomable OLYMPUS M.ZUIKO Digital ED 14-42mm f3.5-5.6 EZ Lens.
The Hungarian regulation of drone flying
Flying in the airspace of Hungary is allowed with an occasional or a limited airspace permit, or with a per-activity permit, up to a height of 150 m, using aircraft weighting no more than 25 kg. The airspace permits within the requested coordinates are provided by the Hungarian Aviation Office, ensuring no other aircraft is using the same airspace during the time of work. No laws specific to drones exist in Hungary; detailed legislation covering the topic is being elaborated. Using drones are permitted on a case-by case permit basis until the relevant law becomes effective. Permits are issued by the Aviation Office of the Hungarian Transport Authority. The permission of the land owner of the related area is also needed for flying. Relevant regulation is found in multiple laws: see law XCVII of 1995 about aviation, governmental decree 4/1998 (16th Jan.) about the use of the airspace of Hungary, ministerial decree of the Minister of Transport and Water Management 14/2000 (14th Nov.) about flight operations and their regulation within the airspace and at the airports of the Hungarian Republic, joint ministerial decree of the Economic, Defense and Transport and Water Management ministries of 26/2007 (1st March) about the assignment of the Hungarian airspace for aviation purposes, and governmental decree of 399/2012 (20th Dec.) about the order of permissions of airspace teledetection and the use of teledetection information.

Is it possible just rent a drone from us?
No. We have professionals to operate the drone. Simply renting is not permissable.
Is it possible to record sound with the drone in-built camera?
No. The in-built camera does not have microphone. If it is necessary, we can record background noise with separate device.
How big is DJI’s Inspire 1 Pro drone?
Length * Height * Width dimension, without the propellers = 44 x 30 x 45 cm.
How much DJI’s Inspire 1 Pro drone weight?
With basic accumulator the weight is 2935 gramms.
What is the maximum speed of DJI’s Inspire 1 Pro drone?
22 m/sec, means 80 km/hours.
How long can we work without landing at a stretch?
With the basic accumulator we have 13 minutes. With the stronger accumulator we have 18 minutes.
Is it able to fly without the camera installed?
Yes, it can. The camera is not an integral part of self-orientation. The aircraft can fly without the camera, but this way the ability to record images is lost.
How much does it take to fully charge the drone’s controller
The system can be equipped with either one (a single operator controls the flight and the camera) or two remote control units (two operators work simultaneously: one controls the drone flight, while the other operates the camera). Recharging of a remote control unit takes 6 hours. A single charging will enable 4 hours of work. Batteries are inseparable parts of the remote control units.
How much does it take to fully charge the drone’s accumulators
The base 4500 mAh battery is charged in 85 minutes. We provide more than one batteries evety time, each 100% charged. Should there arise a need to charge, we can recharge several high capacity batteries using multiple chargers simultaneously.
Does the whether conditions affect our flying service?
Yes. Even to a level that prevents us from being able to provide services. We do not work in rain and/or in wind of more than 15 km/h. The batteries cannot be exposed to water, and the velocity of wind significantly affects the safe controllability of the drone. We use local weather forecasting software, and use professional anemometers at the location. If the air temperature falls below 5 degrees, then flying is subject to the operator’s discretion. If a sudden, unforeseen change in circumstances occur, we do not provide services due to the possible risk of accidents.
Does the coverage of the area affect our flying service?
Yes. The drone is operated with radio signals, and also sends radio signals to the remote controllers. In open areas where there are not many obstacles affecting radio reception (forests, buildings, towers), the drone control range is significantly larger that at densely covered areas. The best solution is to operate from a height, as in this case radio signals are sent from above, without any obstacles. At densely covered areas the drone can be safely flown at a range of 500-600 metres without the loss of signal. When the drone loses connection to the controllers, it automatically returns to the preset home point. The process of automatic return cannot be disabled.
Does the interference of the surrounding area affect our flying service?
Yes. The drone is operated with radio signals, and also sends radio signals to the remote controllers. Our experience is that mobile phones, wi-fi signal sources or transmission towers do not significantly affect the connection with the drone or its internal orientation devices. However, we have faced serious issues in proximity of handheld radios, walkie-talkies or CB radios; even when they were simply switched on, and even more when they were in transmission. These radio devices are mostly used by police officers, civil guards and security personnel. These devices must not be used within a 5–10 m range of the remote control units. They mainly do not affect the manual controlling of the drone, but the Lightbridge camera image signal sent back may be distorted to a level where the live image cannot be seen on the remote control monitor. In such cases, clear visual contact is needed with the drone, as well as eliminating the source of interference as soon as possible.
Does the location affect our flying service?
Yes. We need a clear and written clearance from the owner of the location.
In outdoor, do we need a direct sight of the drone?
Yes. We do need to have the drone and also it surroundings in direct sight, not only through its camera. Direct sight means a maximum of 1 000 meters perimeter.
Does a large body of people affect our flying service?
Yes. We do not fly over a large body of people. Life safeguarding is the most important thing during flying.
Is it possible to access out-of-the-way location?
Yes. In case, we have off-road Toyota Land Cruiser to be used as means of transportation.
Is it possible to fly and making movie in indoors?
Yes. DJI’s Inspire 1 Pro drone has a new feature in the industry. This is the Optical flow technology introduced with Inspire 1. It has made indoor flying significantly simpler. Indoor flying without GPS signal was a challenge earlier, but keeping steady position with Optical Flow is a snap. In addition, landing pads open quickly, making landing initiated with a push of a button a lot easier.
It is possible to fly indoors without line of sight?
Yes. However, some conditions must be met. The first one is the size of the interior airspace. The drone has a horizontal amplitude, therefore at locations where there are many objects in the drone’s way, a direct visual contact is necessary. Concrete has the ability to absorb and block radio signals, while reinforced concrete (containing iron) may even result in a Faraday’s cage effect. In such cases, a close radio connection must be established with the drone, and it cannot be controlled from the outside of the building. In indoor areas where multiple radio sources exist, serious interferences may occur, which adversely affects the radio connection between the remote control unit and the drone.
Is it possible to ban the drone fromn flyiong into specific locations?
Specific drone brands has unique capabilities to ban their drones from flying into forbidden locations. The EHANG, Horizon Hobby, DroneDeploy, YUNEEC, HEXO+, PixiePath and the RCFlyMaps comnpanies has established the NoFlyZone.org web portal.
Does every fly has it own and detailed log-book?
Yes. We can hand over the detailed fly log-book. In case, it is possbile to put those data to the ready to use movie, in expressly stylish form.
Does the drone haul anything else than its camera?
Does the drone camera have automatic exposure?
Could be. Camera can be fully operated remotely.
What does DJI’s Inspire 1 Pro drone’s intelligent accumulator mean?
A fully integrated intelligent battery powers your Inspire 1 Pro and virtually manages itself. When in flight, your remaining battery power is shown live, letting you know how long you can continue to fly. Advanced algorithms calculate the distance of your aircraft and estimated time to return home, letting you know when it’s time to fly back. The battery reports the voltage of each cell, the total lifetime charges and discharges, and the overall health and battery status. All this helps you keep your Inspire 1 Pro in the air and flying for years to come.
What does dynamic home-point mean?
When GPS signal is available on the remote, the Home Point automatically refreshes. This becomes useful while traveling in a car or on a boat allowing the return-to-home point to move where the operator goes. Multiple configurations are available via the Dynamic Home Point function.
Is it possible to watch what drone’s camera see in live HD picture during the flight?
A beautiful, 720p HD view shows you exactly what your camera sees at all times. We can frame our shots and fly as though we’re in the sky ourselves. This is made possible by an all new and improved version of DJI’s Lightbridge technology which can transmit video from up to 2 kilometers away. Or more.
Does the HD view have delay?
The transmitted video usually has a 220ms delay.
What is aspherical distortion?
Most lenses are polished into a shape as if being a part of an orb surface. Their surface shape has the drawback of not focusing light into a single point, but spreading it to a larger area. This results in perspective distortion, which is either of barrel or pincushion distortion type. In the former, straight lines bend towards the edge, while in the latter, they bend towards the centre of the image. In order to eliminate such distortion the camera of Inspire 1 Pro has been equipped with aspheric lenses, the surface of which is not a regular orb, thus providing the necessary correction.
What makes the DJI Inspire 1 Pro camera unique?
Inspire 1 Pro is equipped with a DJI X5 Zennmuse camera. It has a powerful Micro Four Thirds sensor that’s absolutely revolutionary for an aerial camera. With a sensor eight times thesize of that in the previous X3 camera included with the Inspire 1, this new MFT sensor enables high quality, high sensitivity image recording at an ISO range of 100-25600. With a sophisticated balance of high-resolving power, accurate gradation, and low noise, you are realizing yourartistic and creative vision as never before.
The type of CMOS used within the camera is a significant technical detail, but the lenses used are even more important. Light is mediated to the sensor via the lenses. This camera is equipped with special lenses rendering zero-distortion, crystal clear images. Most lenses are polished into a shape as if being a part of an orb surface. Their surface shape has the drawback of not focusing light into a single point, but spreading it to a larger area. This results in perspective distortion, which is either of barrel or pincushion distortion type. In the former, straight lines bend towards the edge, while in the latter, they bend towards the centre of the image. In order to eliminate such distortion the camera of Inspire 1 has been equipped with aspheric lenses, the surface of which is not a regular orb, thus providing the necessary correction. From January, 2016 our company uses Zenmuse X5 for filming and shooting.
What is Zenmuse X5?
Our DJI Inspire 1 Pro is equipped with a DJI X5 camera. Zenmuse X5 or Zenmuse X5R is the first Micro Four Thirds cameras designed for aerial use. Xenmuse X5 supports three lenses in addition to DJI’s MFT 15mm f1.7 ASPH lens made for the X5: the Panasonic Lumix 15mm G Leica DG Summilux f1.7 ASPH lens and Olympus M.Zuiko Digital ED 12mm f2.0 and M.Zuiko 17mm f1.8 lenses. For now lens support is limited because in order to keep the camera stable in flight, the 3-axis gimbal reads the lens profile and uses the information to adjust the motors for the weight and center of gravity along with a lens hood weighted to help keep balance. Shooting modes include program, shutter-priority, aperture-priority and manual. Focus can be set to auto or done manually with focus peaking available to help there and zebra patterning to assist with exposure. The sensitivity range is selectable from ISO 100 to ISO 25600. Flight time will not be shortened using X5 instead of X3.
