  • What is Active Vehicle Control (AVC) in RC Cars?

    AVC, What’s all that about? Ever had an R/C car that was too fast to drive in a straight line? Struggled on loose surfaces? Lost the back end going around corners? Well not to worry, Spektrum has you covered with its proprietary AVC (Active Vehicle Control) technology, allowing beginner enthusiasts to control high powered cars with a level of precision that was previously unattainable. AVC works by utilizing accelerometer’s and sensors inside the receiver to give feedback about the cars movement and relative position. This feedback is then taken and turned into a steering and throttle input. The input will apply throttle and steering correction to keep the car pointing in the direction you choose, these corrections are made so fast that you’re unable to feel them whilst they work seamlessly behind the scenes to provide a driving experience that is precise and c...

  • How do I choose a battery connector?

    We're going to take a walk through the types of battery connectors on offer and also the ones that will work with multiple brands to make understanding your “plugs” that little easier. A majority of the batteries within the RC market come with four main plugs fitted, these are Deans, EC3, XT60, and JST, or some variant of these like EC5 (a bigger version of the EC3 which can handle higher current through it). All these serve a purpose. When fitting a new plug the Deans style are normally easier to work with (solder) if you have some experience as they have a small tab to solder onto. It means that any overheating of the tab while soldering can result in heat transferring to the plug housing, for beginners out there,...

  • What is a Radio Transmitter Mode and what does Mode conversion mean?

    What does Mode refer to when purchasing a model aircraft radio transmitter (controller)? The Mode of an aircraft transmitter is the configuration of the primary flight control sticks. Typically Throttle, Pitch, Roll and Yaw. For the most part, transmitters can be purchased in either mode. For the minority that can only be purchased in a certain mode, brands like Spektrum, Jeti and HiTec can have a mode conversion performed. Mode 1 and 2 being the most spoken about, but Mode 3 and 4 also available in some cases. What Mode should I choose? This is a question we get asked regularly from new customers. In the early days of model aviation here in Australia model aircraft were traditionally flown on Mode 1 (throttle control on the right stick). This has...

  • 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...

  • What is SAFE Technology for RC aircrafts?

    What is SAFE Technology for RC aircrafts?
    As you are browsing through the Modelflight website you will notice that quite a few of the newer releases from Horizon Hobby are equipped with an S.A.F.E receiver but what is it exactly? What is for and how do you use it? 1. Sensor Assisted Flight Envelope S.A.F.E technology or (Sensor Assisted Flight Envelope) came about around five or so years ago in 2013 developed by the good folks at Horizon Hobby who essentially wanted to help or assist inexperienced RC pilots gain confidence when flying. The first time we saw SAFE it was partnered with a re-release of arguably the most popular training plane ever sold – The E-Flite Apprentice. This was an absolute game changer and revolutionized the way we look at the world of trainer aircrafts...

  • Nitro vs Electric Powered RC Cars

    The Great Debate! Nitro vs Electric Power? What is right for YOU? The oldest argument in the book surrounding remote control cars is the choice of the power plant, the rev heads amongst us will say nitro is the only way to go for a realistic experience and the tech heads will back in the incredible performance of Electric brushless systems and the hassle-free nature of electric power. There are so many factors to consider when choosing a car and the type of power system that car runs will come down to a variety of factors. Ultimately the option you choose to go with will be dependent on the experience you wish to have and the time you wish to dedicate to the R/C hobby, let’s break down some of the Pros and Cons of both options...
