# 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 featur e, 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 el ectronics 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 automaticall y flies back to the starti ng point and land there.

Automatic takeoff and landing These advanced features allow even beginning pilot’s to takeof f and land safely without any risk of tip-over accidents or bouncing that might otherwise damage the copter. Using a lapt op 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.

Redundant Flight Control Systems Mikrokopter’s Flight Control Systems offer special redundant safe ty 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 ther e 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 pano rama, rotating and tilting the camera to create a mosaic of appropriately overlapped imag es that can be stitched together like this to form a beautiful panoramaInverses Panorama With a Circle-of-Interest-Funktion (COI) it is possible to surroundan 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 transmi tter 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 yo u can save waypoints as relative positions to the previous waypoint – and rotate the relative position depending on the orientation of the copt er. For example, go to 50 meters to the left of the present position – this will va ry depending on the copter’s orientation. Relative waypoints can be preset just usin g 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 automa tically 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 Überla ppung gemacht. Dies reduziert die Anzahl von Wegpunkten erheblich. Mit z.B. 16 Wegpunkten erreicht dieses System di e selbe effektivität, wofür andere hunderte Punkte bräuchten.

Flugsimulation im Kopter Eine Flugsimulation ist in der Firmware des MikroKopters integriert. In der Simulation lä uft 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 Flugsimula tor, 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 da ta 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 ca mera angle to the ground can be changed using a control on either the pilot’s RC transmitter – or a separa te 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 val ue, 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 pr ovide 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 controll ers – 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 controller s write their status, temperature, and the electrical current bei ng provided to the motor to a log file. Any overload or motor failur e 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 mi crocomputers are used for flight control, navigation, motor controls, GPS, camera interface and other functions. The comput er 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 th e Earth’s magnetic field to help with navigation. A highly sensitive pressure sensor, combined with the accelerometer da ta 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 antenn a 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 posi tion 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 batt ery 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” be tween the instructor and the student’s transmitter – it can all happen wirelessly. Better yet, specific channels for controllin g 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 cameraoperator 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), CareFreeMode (which allows beginners to fly without worrying about control reversal), Automatic take-off and landing to make learning to fly safer, Fa ilsafe (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 invi sible 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 co pter, 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 fo r the Flight Controller, Navigation Controller, GPS board, and the Brushless Controllers. You also get the free Configuratio n program, Mikrokopter Tool (f or Windows PCs), an Android tablet based flight planning tool, MKTT, for setting up waypoint s, 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. Finall y, we also provide a free flig ht 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 differ ent 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 oursel ves 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 re turn to the take-off point automatically.

Carefree Mode for Beginners One of the hardest things for beginning pilo ts 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 pilo t, 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 ad justed in flight if the pilot wa nts 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 te ll 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 copt er is resting on a moving boat.

Long Distance Waypoint Flying Mikrokopter permits waypoint flying up to 250 meters from th e take-off point. If you need to pre-program more distant waypoints, all you need do is purchase an extended range licen se and copy the license file on to the microSD card in theNavigation Control Board.

Easy Maintenance and Simple Modular Design The Mikrokopter multi-rotor copters are easy to maintain and repair. Th ey use interchangeable parts that are easy to replace without coming back to the workshop.
