  • What is an Electronic Speed Controller and how does it differ from brushed to brushless motors?

    An Electronic Speed Controller (ESC) is a device that regulates the power of an electric motor, allowing it to throttle from 0% to 100%. There are two styles of Electronic Speed Controller, Brushed and Brushless. Both work on the same principle. An ESC is made up of three key components. A BEC/voltage regulator, a Processer and the switching consisting of FETs (field effect transistor). Now let's get a little technical. The BEC/voltage regulator is a division of the ESC that will send a set amount of power (typically 5v 1Ah) back to your receiver to then power your servos. This also has a secondary function whereby if the battery that is driving the motor reaches its minimum voltage the BEC (Battery Eliminator Circuit) will reserve power for the flight critical controls, making sure the motor doesn't take all the power from the battery. The processor...

  • Understanding 2.4GHz Radio Frequency

    Understanding 2.4GHz Radio Frequency
    Many transmitters work on 2.4GHz protocols. What is it, and can I use any receiver with any transmitter? The 2.4Ghz band was first introduced to Radio Control by the Spektrum brand with the now famous Spektrum DX7 Transmitter. It replaced ‘crystal’ technology which consisted of the 36, 40 and 27mhz systems that were on a given ‘channel’. There were many reasons for the change, however the most relevant is to allow more available frequencies, or “spots”, for people to operate their models on. The 2.4Ghz offers incredible reliability, the shorter wavelength also brings less signal penetrating power (less range), however, this can be combated with a higher RF (radio frequency) power output which is built into 2.4Ghx Transmitter systems. Longer wavelengths like the old 36, 40 and 27Mhz bands did offer that long wavelength and penetrating power for a relatively low radio-frequency power outputs but...

  • Trimming Techniques for Multi-Channel Gliders

    A gliding retrospective Written by Mike O'Reilly The Model Make every effort to have a ‘straight’ model This was important when you built your own model from balsa and foam, but modern moulded gliders rarely have warps or heavy panels Trimming The whole purpose of the trimming process is to make your glider easy to fly in a ‘hands-off’ situation. The easier it is to fly, the better it will fly. I like my gliders to be neutrally stable so they will fly hands off. This helps you to detect thermals in the first instance and to be comfortable flying your glider a long way downwind. Tow Hook Position With very few exceptions the tow hook should be placed in front of or on the CG. The ideal position also depends on flap and elevator presets so there is no definitive position. Moving the hook rearwards will increase the steepness of the climb,...

  • 2016 SCHOOL THEME: DRONES, DROIDS AND ROBOTS

    In Australia, the National Science Week is an annual celebration of science and technology. It is held at schools throughout the nation with thousands of individuals – from students, to professionals – getting involved, taking part in more than 1000 science events across the nation. This year Modelflight were fortunate enough to play a small part in this curriculum initiative holding sessions at two local primary schools; Burnside Primary and Scotch College Junior School showing some of the technologies involved with drones and multirotors. While visiting the two schools we spoke with around 250-students from middle to upper primary year groups...
