Exhibit “A” Features of the MicroKoter:

GPS Flight Assistance and Autopilot 

The GPS Navigation Control board is a key component and provides an autopilot that can control the position and course of 

the copter. It provides a Position Hold and Come Home feature, as well as the capability for autonomous flight between 

waypoints.

PositionHold 

Position Hold keeps the copter at the same place in the sky even in strong winds, leaving you free operate the camera and 

get the shots you want. 

ComingHome 

With the flick of a switch on your transmitter, the Navigation and Flight controllers make the copter climb up to a preset 

height, and fly it directly back to the take-off position..

Dynamic Position Hold 

Even while the Navigation Control board is in Position Hold you can “fly” the set point position and this allows you to fly the

copter in a straight line even when it is windy – a great feature for shooting tracking video shots.

Wind and Weather 

Equipped with a dome cover, Mikrokopter electronics allow the copter to be flown safely even when it is windy and raining.
Auto - ComingHome 

If the battery reached a critical value, the MikroKopter automatically beep and gives you an information via the telemetry. if 

you do not notice this, the copter will automatically flies back to the starting point and land there.

Automatic takeoff and landing 

These advanced features allow even beginning pilot’s to takeoff and land safely without any risk of tip-over accidents or 

bouncing that might otherwise damage the copter. Using a laptop computer or Android tablet you can pre-program entire 

flights from takeoff, flying to specific way points at specific heights, triggering the camera shutter, and then returning back to

the takeoff position and automatically landing. (Demovideo)

Redundant Flight Control Systems 

Mikrokopter’s Flight Control Systems offer special redundant safety features. On an octocopter, the failure of one motor will 

not cause a crash and the copter will continue to fly safely. Mikrokopter also offers systems with duplicate Flight Control 

boards that keep the copter stable even if there is a failure in the primary Flight Control board.

Waypoint Flying 

Using a Windows laptop or a computer, or an Android tablet, even beginning pilots can enter a preset flight plan and the 

copter will fly between waypoints at a preset speed from 0.36 km/hour up to 54 km/hour. As an option, the pilot can change 

the inter-waypoint speed using a control on the RC transmitter.

Automatic Panoramas 

With the flick of a switch on the RC transmitter, the copter can automatically take a panorama, rotating and tilting the 

camera to create a mosaic of appropriately overlapped images that can be stitched together like this to form a 

beautiful panorama
Inverses Panorama 

With a Circle-of-Interest-Funktion (COI) it is possible to surround an object and aim with the camera at the center.Perfect for

video, documentation and 3D-measurements. 

Position Save 

You can easily save a new waypoint as you fly the copter so that you can bring the copter back to that same place in the sky

– you don’t even need a laptop or tablet to do it. All it takes is a switch on the RC transmitter and the copter will fly back to 

the saved position.

Save a Tracking Shot 

You can save 3D waypoints during flight with your RC transmitter and then command the copter to fly the same ground track

repeatedly as you shoot multiple takes. You can adjust the ground speed from 0.1 meters/second to 10 meters/second with 

a rotary control or slider on your RC transmitter. You can even change batteries and recall a previously saved tracking shot.

Relative Waypoints 

For applications such as panoramas or large-scale mapping you can save waypoints as relative positions to the previous 

waypoint – and rotate the relative position depending on the orientation of the copter. For example, go to 50 meters to the 

left of the present position – this will vary depending on the copter’s orientation. Relative waypoints can be preset just using 

the RC transmitter and without the need for a laptop or tablet.

Point of Interest (POI) 3DWaypoints 

For imaging ground-based features like buildings or other structures, you can program 3D waypoints around the particular 

point of interest and the copter will automatically turn to face the POI as it flies between the waypoint. Each waypoint is both

a position and a height.
Flexibles Autotrigger 

Eine Kamera kann entweder zeitgesteuert, per Wegpunkt oder sogar abstandsgesteuert ausgelöst werden. Alle 15m ein Foto,

egal wie schnell man fliegt? Kein Problem! Damit wird das Abfotografieren von großen Flächen zum Kinderspiel. Dieses 

Feature lässt sich auch mit Waypoint-Flügen kombinieren -> es reicht also, vom Gebiet nur die Eckpunke per Waypoints 

anzufliegen. Trotzdem werden Fotos mit ausreichender Überlappung gemacht. Dies reduziert die Anzahl von Wegpunkten 

erheblich. Mit z.B. 16 Wegpunkten erreicht dieses System die selbe effektivität, wofür andere hunderte Punkte bräuchten.

Flugsimulation im Kopter 

Eine Flugsimulation ist in der Firmware des MikroKopters integriert. In der Simulation läuft der Flug mit den originalen 

Routinen im MikroKopter ab. Die virtuelle Position kann am PC beobachtet und per Sender oder Wegpunkten gesteuert 

werden. Optimal zum Testen von Kamera-Auslösungen bei Wegpunktflügen usw. Selbst Logfiles werden mit den Simulierten 

Daten erzeugt. Außerdem haben wir einen Flugsimulator, der Flugtraining mit dem originalen Sender 

erlaubt. (Siehe: Simulation 1, Simulation 2)

Flight Data Logging 

For post-flight analysis you can log data five times a second to a micro-SD card on the Navigation Control board. This 

information contains numerous relevant data values including GPS-position, height, speed, voltage, position of switches, 

flight attitude, currents of each motor, temperature, pilot and autopilot inputs.

Take-off weight and payload 

The Okto-XL 6S12 weights 2.6 Kg, a typical LiPo battery is 0.75 Kg, a total of 3.35 Kg. In addition the Okto XL 6S12 can 

carry a useful payload of 4 Kg.
Automatic Camera Tilt Compensation 

Copter motion is automatically removed so that the actual camera angle to the ground can be changed using a control on 

either the pilot’s RC transmitter – or a separate RC transmitter for the camera operator.

Emergency Failsafe Recovery 

If the copter’s flight control receiver loses contact with the pilot’s RC transmitter, the copter will automatically return to the 

take-off point at a preset height chosen by the pilot. If the flight battery voltage drops below a pilot-selected threshold value,

the copter will also return to the take-off point, and, if the pilot preset the option, will automatically land.

State-of-the-Art Motors 

The compact brushless motors we use are minimum-wear and provide high performance and a long service life. We use our 

own test stand to determine the efficiency of different motor/propeller combinations.

Next-Generation Brushless Motor Controller 

We have designed our own high power brushless motor controllers – they can provide 1 kilowatt of power to each motor. 

When the controllers need to slow a motor down, they use active braking to recovery electrical power, feeding it back to the 

flight battery, making for longer flight times. The controllers write their status, temperature, and the electrical current being 

provided to the motor to a log file. Any overload or motor failure status is immediately downlinked to the pilot on the ground.

A redundant data bus provides additional safety margin.

Open Interface 

The serial protocol for controlling and configurating the MikroKopter is open and documented. Control the Copter with your 

own firmware via wireless telemetry intercace or an own controller on board.
Advanced 32-bit ARM and AVR Central Processors 

Depending on the number of motors, from 12 to 15 single chip microcomputers are used for flight control, navigation, motor 

controls, GPS, camera interface and other functions. The computer source code for these microcontrollers is Open Source, 

written in C, and can be modified by our customers if required.

Cutting Edge Nanoscale Sensors 

IWe use the state-of-the-art nanotechnology sensors for solid-state gyroscopes and accelerometers to measure the attitude 

and movement of the copter. A 3D Hall Sensor compass reads the Earth’s magnetic field to help with navigation. A highly 

sensitive pressure sensor, combined with the accelerometer data provide a “height hold” and allows for automatic take-off 

and landing.

Advanced Global Positioning System 

The GPS board uses the most recent, highly-sensitive GPS antenna and preamplifier with a SAW frequency filter that can get 

a 3D position lock with a limited sky view or when satellites are shielded by terrain and buildings. This system can get 

positional data from the U.S. GPS, the Russian GLONASS, and the Chinese BeiDou satellites. 

Telemetry via Personal Computer or Tablet 

MikroKopter’s copters have a bidirectional telemetry system with a range of up to 6 Km and operating at different 

frequencies (2,4Ghz, 868Mhz, or 900Mhz) display copter position and operating parameters on a PC or tablet. These 

parameters include the copter’s height, flight battery voltage, elapsed flight time, motor currents and more. This telemetry 

data can be integrated with Google Earth for navigation or stored for offline use and integration with your own map data.
Voice Announcements and Logging of Telemetry Data 

- z.B. Jeti oder Graupner HoTT For certain RC Transmitters such as JETI or the Graupner HoTT the transmitter can speak 

flight critical information out loud. This includes flight battery voltage, height, distance, mode changes, and errors. These 

voice announcements can be made predetermined time intervals or in response to a control switch on the RC transmitter. 

This telemetry data can also be logged in the RC transmitter – for example, the last GPS position in the case of a crash or 

loss of contact with the copter.

Long Flight Times 

Depending on the weight of the aircraft and the batteries being used, copter flight times can be as long as 40 minutes. We 

provide free software that helps you predict what likely flight times will be.

Instructor and Trainee Pilot Systems 

Using Graupner HoTT transmitters and receivers, there is no need for a “buddy cable” between the instructor and the 

student’s transmitter – it can all happen wirelessly. Better yet, specific channels for controlling the camera and even copter 

yaw control can be assigned wirelessly to a second transmitter for a camera operator.

Camera control and Zoom 

Mikropkopters Sony LANC control allows the pilot or the camera operator to have full control of starting/stopping video 

recording, shooting still images, and zooming the camera lens in and out. 

Safe and Easy Flight Operations 

lying a Mikrokopter multi-rotor copter is safe and easy because we have such features as Come Home (which brings the 

copter home at a preset altitude), CareFree Mode (which allows beginners to fly without worrying about control reversal), 

Automatic take-off and landing to make learning to fly safer, Failsafe (which brings the copter home on loss of contact with 

the RC transmitter) and Geo-fencing (which confines the copter to specific territory).
Geo-Fencing for Safety 

Mikrokopter provides programmable features that create an invisible cage in the sky. When enabled the copter will never fly 

outside this cage and can thus remain safely in view even when a novice pilot is flying the copter.

Almost Ready-to-Fly Copters 

All you need do is unbox the copter, charge up some batteries and install the propellers on the copter and you are ready to 

fly.

Live Payload Video Downlinked to the Ground 

Dhe payload camera can downlink a wireless video feed so you can watch the video either on a monitor screen or using 

video goggles during the flight.

Free Mikrokopter Software 

Mikrokopter provides free software updates for new features for the Flight Controller, Navigation Controller, GPS board, and 

the Brushless Controllers. You also get the free Configuration program, Mikrokopter Tool (for Windows PCs), an Android 

tablet based flight planning tool, MKTT, for setting up waypoints, and geo-fencing. We also provide a free flight simulator, 

AeroSimRC (the software is free, but you need to purchase a USB dongle), so that you can learn to fly a copter without 

expensive crashes and whatever the weather is doing outside. Finally, we also provide a free flight time calculator so you can

predict your flight times, and a special tool for reviewing the GPX flight data logs created by the Navigation Control board.

Mikrokopter Avionics Are Widely Used 

Mikrokopter avionics boards are widely used on many different brands of copters – you may not see the Mikrokopter name, 

but it’s often there under the protective hoods. There are thousands of copters flying Mikrokopter avionics.

Source Code 

Mikrokopter makes is source code available under an Open Source licenses so you can easily tailor it to your needs. Note: to 

compile the Navigation Control board source code you need our Lib-Link license.
Made to German Engineering Standards for 15 Years 

or the past 15 years, Mikrokopter has developed its own hardware and software for the Flight Control, Navigation Control, 

GPS, and Brushless Controllers. We pride ourselves on high quality hardware and software.

Low-Stress Panic-Free Flying 

If you simply let go of the RC transmitter sticks and let them return to their center position, the MK Avionics will bring the 

copter to a standstill in the sky so that you can decide what you need to do next. If you operate the GPS switch, the copter 

will go to a preset height and then return to the take-off point automatically.

Carefree Mode for Beginners 

One of the hardest things for beginning pilots to master is the control reversal when the copter flies with boom #1 pointing 

in any direction but away from the pilot. Worst case, if boom #1 points at the pilot, all left/right control inputs must be 

reversed and this can easily cause a beginner to lose control and crash the copter. That’s where Carefree Mode comes in – it 

automatically senses where boom #1 is with respect to the pilot and allows to pilot to fly “nose out” all the time, regardless 

of the copter’s actual orientation. Carefree Mode can also be adjusted in flight if the pilot wants the copter to fly around to

the side or behind the pilot.

Click and Fly : Single Point Navigation 

With just a single click or tap on a map on the screen of a PC or Android tablet you can tell the copter where to fly and 

autoland there.

Boat Mode : Advanced Feature 

IThis is an advanced feature that permits the pilot to initialize the solid state gyroscopes for safe flight even when the copter 

is resting on a moving boat.

Long Distance Waypoint Flying 

Mikrokopter permits waypoint flying up to 250 meters from the take-off point. If you need to pre-program more distant 

waypoints, all you need do is purchase an extended range license and copy the license file on to the microSD card in the 
Navigation Control Board.

Easy Maintenance and Simple Modular Design 

The Mikrokopter multi-rotor copters are easy to maintain and repair. They use interchangeable parts that are easy to replace 

without coming back to the workshop.
