RC Frequency Selection for FPV UAV LRS

There are several frequencies to choose for your RC transmitter and receiver by swapping “piggybacks” or “backpacks” onto your RC transmitter. For long range choose 443MHz. Be sure not to choose the same frequency that your video transmits on. I recommend 433MHz 500-800mW for RC and 1.3GHz 800mW for video long range and 900MHz for…

Mantras to use when building unmanned planes

Lightness and Efficiency are paramount – These are the keys to high performance in all aspects of aeronautics. All high performance aircraft is dependent on this simple concept and should be the defining principle in your design. K.I.S.S. (Keep It Simple Stupid) – Simple engineering is generally better. In the case of aeronautics; simplicity could…
