Industrial 6-Rotor Unmanned Helicopter Provides High Definition Wireless Video and High Resolution Photographs
Draganfly Innovations releases the Draganflyer X6 helicopter. This remotely operated, unmanned, miniature helicopter is designed to carry wireless video cameras and still cameras.
Saskatoon, Saskatchewan (PRWEB) August 27, 2008, Draganfly Innovations announced the launch of the Draganflyer X6 helicopter, a miniature aircraft for commercial/industrial aerial video and photography. The Draganflyer X6 helicopter is easy to fly, capable of operating autonomously, and has an appearance that is nothing like a conventional helicopter. The unique design utilizes six main horizontal rotor blades and allows the Draganflyer X6 helicopter to hover efficiently and maneuver rapidly using differential thrust.
Remotely controlled aircraft are available for many purposes, and most fall into a class somewhere between toys and the high quality models piloted by hobbyists. Beyond this class is a large gap approaching the point where full size aircraft must be used to achieve tasks such as commercial photography and industrial inspection. In the past this gap was filled by model aircraft with additional equipment grafted on, which required skilled and trained pilots to operate. Draganfly Innovations has created a better alternative; a purpose built self-stabilizing multiple rotor helicopter specifically designed for filming high definition video and photographing high-resolution aerial pictures.
The Draganflyer X6 is a fully functional miniature unmanned electric powered helicopter. Aimed at industrial and commercial use, it provides reconnaissance and inspection information using on-board wireless video and still cameras. The Draganflyer X6 helicopter is able to fly autonomously or can be flown manually by remote control. The Draganflyer X6 helicopter achieves its stability by using an on-board processor running more than ten thousand lines of code and receiving data from eleven on-board sensors (three gyros, three accelerometers, three magnetometers, one barometric pressure sensor, and one GPS receiver). It can be piloted by users with minimal or zero training. The Draganflyer X6 helicopter determines its own orientation and motion and moves where the operator instructs it, automatically handling the complex attitude and altitude adjustments that would ordinarily require a practiced pilot. “The ease with which this helicopter can be piloted is the most revolutionary feature of the Draganflyer X6″ says company president, Zenon Dragan.
The Draganflyer X6 helicopter can be put into GPS hold mode where it will maintain its position without any user input. This means that after activating GPS hold, the pilot can set the handheld controller on the ground while the Draganflyer X6 helicopter flies itself. This mode will allow the user to focus on other tasks such as aerial photography from the Draganflyer X6 helicopter.
The Draganflyer X6 helicopter uses interchangeable cameras, covering different areas of use. A high definition video camera provides 1080p resolution. For dawn and dusk use, there is a low light (0.0001lux) video camera. For night use or search and rescue, the thermal FLIR (Forward Looking Infra-Red) camera provides heat vision. High-resolution photographs can be captured with the 10.1 mega-pixel digital still camera. When using any of the camera modules, a viewfinder video signal is streamed wirelessly back to the operator for real-time viewing on video glasses. The camera mount tilts by remote control, and the helicopter can pan side to side or in a circle.
The Draganflyer X6 helicopter uses six custom designed high efficiency carbon fiber rotors and direct drive brushless motors which result in a quiet and maintenance free helicopter. The Draganflyer X6 helicopter weighs 1kg and has a payload capacity of 500 grams.
Durability and safety have been incorporated into the design of the Draganflyer X6 helicopter. With dual motors on each of the three arms, even if an in-flight collision causes one of the motors or rotors to stop working, the Draganflyer X6 helicopter will still be able to keep flying using the remaining five motors. This ability to fly with a missing motor or rotor is not found in any other comparable helicopter. Other safety features include bright LED navigation lights for safe flying at a distance or in darkness, and automatic self-landing if the radio link controlling the helicopter is lost. An on-board flight recorder (black box) stores telemetry and flight data in a removable memory card, and can be used for post flight analysis.
The Draganflyer X6 helicopter is flown using a custom designed handheld controller with a 2.8″ color OLED touchscreen that displays telemetry and flight data. The handheld controller also receives streaming video sent by the Draganflyer X6 helicopter and passes this to the video goggles, enabling the operator to view what the helicopter is seeing while also keeping an eye on the helicopter itself.
Brushless Motors and ESCs August 14, 2008
- Revised Can Design – Hacker has revised the motor’s external case to allow for better airflow and cooling towards the back of the motor.
- New Stater and Magnet Material – Hacker has re formulated the material used for the stater and magnets in their brushless motors. The new material has a lower internal resistance, which gives the motors more power and efficiency.
- Collet Style Adapter – The new evo motors use a new style of prop adapter, which is more secure and easier to use than the previous versions. The new adapter also allows the motos to be more easily mounted either in front or behind an RC model airplane firewall.
- New Mount – All of the A20 series motors now feature a new type of mount which allows the new can design to work.
All of the Hacker A20 brushless motors except the A20XL incorporate this new design, including the A20, A20S, A20M, and A20L.
All of the A20 brushless motors we sell will be revised to this new design, so why not get one for your electric RC model airplane today?

Like all new aerobatic maneuvers, perform the rolling loop at a high altitude when you first learn it. This ensures that you have sufficient altitude to recover from most mistakes. Try the rolling loop in the direction that you’re most comfortable rolling. After you become more familiar with it, you can roll in any direction you want.
Follow this procedure to perform a rolling loop:
- As with almost every aerobatic maneuver, begin by climbing to sufficient altitude and facing into the wind.
- The objective of this maneuver is to execute a round loop and a 360 degree roll at the same time, so increase throttle to full and begin climbing.
- As you’re RC model airplane climbs, use a small amount of rudder to hold it in a vertical position.
- Continue to use up elevator and aileron to roll and climb. Control the roll rate so that the RC model airplane’s wings are level at the top of the loop.
- Decrease the amount of rudder input so that the RC model airplane “falls” over the top of the loop.
- Decrease throttle, and continue using aileron and rudder to maintain a constant roll rate.
- Aim to have the wings level again at the cardinal point (the point at which you first started the maneuver.)
Congratulations! You now know how to successfully perform the rolling loop!
Are you interested in some cheap, fun RC model airplanes? Foamies have been built by DIY modelers for years, who have created an abundance of free plans and patterns on the internet. Most of the time all that you need to build a great foamie is a sheet of wall insulation, some radio and engine gear and a printer. This article will show you a general procedure that you can follow to construct foamies using common household and hobby supplies.
- Download and print one of the free patterns available on the internet. The one that you choose largely depends on your personal building experience, the supplies you have, and the amount of time that you are willing to put into the project. Some plans need to be scaled up or down. If you don’t want to do this yourself most print shops will reproduce and scale images for you.
- Transfer the paper pattern to the foam core you obtained earlier. There are several ways to do this, but if you want to preserve the plan you can lightly score over the outline with a ball point pen. This indents the foam below and creates a pattern for cutting.
- Cut out the pattern that you made with a sharp hobby knife, being careful to follow the lines accurately. If you make a mistake round it out using medium grit sand paper and a sanding block.
- Round out the leading edge of the wind a fuselage by first using medium, and then fine grit sandpaper.
- Give the wind an airfoil by making three bends along it’s length. Some patterns include the desired airfoil section – so if yours does use it as a reference.
- Sand some dihedral into the wing and glue the wing halves together using either foam safe cyanoacrylate or hot glue (available in most craft stores.)
- Assemble the model using your adhesive of choice.
- Unless your model’s pattern was meant to be glued to the foam – you will probably want to add some color. Spray paint is a great way to decorate your finished model, but be sure to use satan paint – not enamel. Most enamel paints react badly with foam.
- Mount your servos by cutting rectangular holes in the wings and fuselage, and pressing them in.
- The brushless motor is usually mounted by on a wooden dowel glued to the fuselage, and the radio and batteries can be secured to one side of the fuselage with velcro.
- As a last step add the control surfaces and hinge them with clear packing tape.
If you want some free patterns and instructions, check out this RCGroups.com thread. Many foamie fans have contributed great models and posted them for everyone to use. Have fun with your foamie RC model airplanes!

Like with RC model airplanes, RC helicopter transmitters have different modes of operation, which determine which stick does what. This article will show you the four different transmitter modes.
Mode 1 RC Helicopter Transmitter
Mode 1 RC helicopter radio transmitter: the left stick controls fore and aft cyclic and left / right yaw, and the right stick controls the throttle and left / right cyclic.
Mode 2 RC Helicopter Transmitter
Mode 2 RC helicopter radio transmitter: the left stick controls the throttle and left / right yaw, and the right stick controls the fore / aft cyclic and left / right cyclic.
Mode 3 RC Helicopter Transmitter
Mode 3 RC helicopter radio transmitter: the left stick controls fore/aft cyclic and left/right cyclic, and the right stick operates the throttle and left / right yaw.
Mode 4 RC Helicopter Transmitter
Mode 4 RC helicopter transmitter: the left stick controls the throttle and left/right cyclic, and the right stick controls the fore/aft cyclic and left/right yaw.

Choosing a Flying Slope
As it’s name implies, slope flying involves launching an RC model airplane from the top of a slope. Slopes are great flying locations, because wind blowing up the slope causes updrafts which RC model airplanes can use to fly.
If you’re interested in slope flying, the first thing to do is to find a suitable place to fly. An ideal slope has an elevation of at least 100 feet, a gradient of 30 degrees, and is relatively free of trees and other obstacles. Most nearby slopes are unlikely to be perfect, but any slope that is relatively high and steep should do. Almost any RC model airplane with a large wing area will glide well enough for slope flying. Both the Multiplex EasyStar and the Vortex Extreme are well suited to slope flying, and can glide for large distances with their motors turned off.
Launching and Flying the RC Model Airplane
After you’ve found a suitable flying location you can begin slope flying. Most RC model airplanes are hand launched for slope flying, so you may want to read our other article: Hand Launching An RC Model Airplane for some pointers. When hand launching your RC model airplane face into the wind and apply full throttle (if the RC model airplane has an engine). Toss the RC model airplane overhand, and use up elevator to enter flight.
Immediately after takeoff, turn the RC model airplane so that it flies parallel to the slope. This puts the RC model airplane in a position where it can catch the maximum amount of upward airflow. If sufficient wind is present, the RC model airplane should begin to climb gradually. After the RC model airplane has gained sufficient altitude, begin a gradual turn away from the slope. Continue the turn until the RC model airplane is parallel to the slope, and continue climbing. This circuit can be repeated as long as the wind remains constant, and the batteries powering the radio components are charged.
Landing the RC Model Airplane
Landing after you’ve finished flying is challenging due to the sloping ground, so follow this procedure when landing your slope flying RC model airplanes:
- Approach the top of the hill at an altitude of about 10 feet.
- Make one wide turn into the wind, and begin your descent so that the plane will land near the center of the hilltop.
- Continue flying into the wind, and gently let the plane settle on to the ground. Have fun slope flying with your RC model airplanes.
Every RC model airplane transmitter has a mode of operation, which defines which sticks control different surfaces. This article will illustrate the differences between them.
Mode 4 Transmitter
On a mode 4 transmitter, ailerons and throttle are controlled with the left stick and rudder and elevator are controlled with the right stick.
Mode 3 Transmitter
On a mode three transmitter, ailerons and elevator are controlled with the left stick and rudder and throttle are controlled with the right stick.
Mode 2 Transmitter
On a mode two transmitter, throttle and rudder are controlled with the left stick, and ailerons and elevator are controlled with the right stick.
Mode 1 Transmitter
On a mode one transmitter, elevator and rudder are controlled with the left stick, and throttle and ailerons are controlled with the right stick.
