RC Airplanes Simplified

The RC Quadrocopter. The Quadrotor Microdrone.

The  RC Quadrocopter is a marvel of technology. How to understand the complexities and what is available today.

 

The photo here shows the Draganflyer X6 .

What is an RC Quadrocopter? Mechanically this has to be the simplest form an RC helicopter can take. Basically we have a brushless motor and a propeller attached to the end of a boom. We can have 3 or 4 or 5,6 or even 8 booms all connected to a center "fuselage"

The fuselage contains the LiPo battery and the control sensors. What cannot be seen is the software required to make the  Quadrotor stable.

As can be seen in the sketch at the left, 2 of the propellers rotate clockwise and the others rotate counterclockwise. The sketch is from the Wikipedia web site.

The propellers are fixed pitch and to control the quadrocopter the speed of the motors can be changed for all the regular RC helicopter motions. This is where the software and sensors come into play-it can get very complex to be able to hover, climb, descend,  turn and rotate, when the only variable is individual motor speed.

However, I believe it is fair to say that this aerial platform is the most stable platform available today. The majority of the development (at least in the early days) was initiated for military and surveillance operations. In fact there is an industry devoted to providing microdrones for aerial photography and similar applications.

The cost of this technology is relatively high for a hobby level flyer, but as always the cost is dropping dramatically!

 

The Hobby level Quadrocopter.

If you would like to build your own quadrocopter, your choices are somewhat limited. I could find only one company offering kits ( See MikroKopter below) You can, of course, decide to design and build your own from scratch. The cost of the technology is reaching reasonable levels and I can point you in a couple of directions, to give you some assistance.
 

This link to RC Groups Forum will give you some ideas that other people have tried. Be warned that this forum is, as of today, over 650 pages long, so you may have to dig to find the useful bits!

  • A large part of the discussion is about a company and their product, intended for use by the hobby enthusiast. The company in question is Hoverfly Quadcopter Flight Control Systems. Hoverfly have developed a PC board that contains all the sensors required for stable, automatic RC flight. To complete your quadrocopter, you need to add-
  1. 4 X Motors ( Brushed or brushless)
  2. 4 X Matching ESCs
  3. 1 X Frame
  4. 1 X LiPo battery
  5. 1 X RC Transmitter
  6. 1 X RC Receiver.

The cost of the board is, at present, $360-so this does fall into the RC Hobby area.

The video below will give you a good idea of the kind of machine that can be built, using this technology for RC flight.

The Parrot AR Drone.

The Quadrocopter. The Parrot AR Drone.

This micro drone is truly an amazing quadrocopter! It is advertised as a "The flying Video Game" and when you start to study this device you can understand why!

Visit the AR.Drone page, on this web site, for full information Maybe the most amazing point regarding the AR Drone is that it is controlled by your iPhone or iPad! You do not need to purchase an expensive RC transmitter to fly this baby!

The accelerometers within the i-device are the quadrocopter's roll and pitch control. This has to be the easiest remote controlled helicopter to fly! It really is a robot microdrone that includes video cameras that feed back to the i-device with real time video.

As you can see from the Amazon.com advertisement,( In the column to the left) the price for this marvel is $300. That includes everything you need to fly-except for the iPhone

The video below shows all the details-take a look-you will not be disappointed!

 

MikroKopter.

This is a German company that does offer complete kits, ready to build, of several different models. Some models have GPS capability, which can result in some remarkable flights! (See the video below)

The Quadrocopter. The Mikrokopter.

The web site has full details of a number of different models and many components.

If you would like to talk to people, who have similar interests, then there is a forum, full of how to do it information and hints and tips to ensure success.

The RC Model Helicopter.

          

A Scale RC Model Helicopter, the Blade Huey UH-1 RTF.

This scale RC model helicopter, is an accurate replica of the Bell Iroquois, from the Viet Nam era. Easy to fly, this collective pitch, remote controlled helicopter is complete and truly ready-to-fly.
