    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 bu...

    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...
