Download RC Speedo

RC Speedo is a speedometer app for EDF's, pylon racers, pushers, and other hi-speed electric radio-controlled airplanes. It works by doing doppler analysis on the sound of an RC airplane making a speed run recorded through the phone's microphone. This method of finding an RC aircraft's speed was pioneered by RC enthusiasts over the past couple of years to accurately calculate the speed of a radio-controlled airplane with nothing but a clean sound clip of the airplane making a speed run past the pilot.

With RC Speedo the process is greatly simplified: just bring your phone to the field and hit "listen". As you make passes with your favorite airplane the phone will report your speeds back at you!

The Android RC Speedo App runs on any Android Smartphone running version 1.6 (Donut) or higher. It works best on devices running version 2.2 (Froyo).

The RC Speedo App works best with electric RC aircraft that have hi-RPM, low-diameter propulsion systems. This includes EDFs, pylon racers, pusher jets, and any other airplane that matches the description. RC Speedo currently will NOT work on planes that are extremely quiet, operate at low RPM's, turbines, most nitro planes, and obviously planes with no propulsion system at all. It also cannot detect anything moving slower than 25 MPH. Future versions may support some of these aircraft types so keep checking back!
