RC Speedo is a speedometer app for EDF's, pylon racers, pushers, and other hi-speed electric radio-controlled airplanes. The application works by performing doppler analysis on the sound of an RC airplane passing in front of the mobile device’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 app will report your speeds back to you in real time!

The iOS RC Speedo App runs on iPhone 3, iPhone4 and iPod Touch Gen 4. RCSpeedo requires the device to have a built in microphone in order to operate.

The RC Speedo App works best with electric RC aircraft that have hi-RPM, hi-blade count propulsion systems. This includes EDFs, pylon racers, pusher jets, and similar airplanes. 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!

RC Speedo is not guaranteed to “hear” every pass. Ensure that the settings are correct for your aircraft and try to make straight and smooth passes. Please consult the manual page at for more information on settings and features. The makers of this app are not responsible for any damage caused to your phone, plane, or self while using this app. Fly safe!
