RC Speedo - A speedometer app for your phone!

 

Hey guys!  A friend and I developed a speedometer app for iOS and Android.  It is a simple to use app that allows your mobile device to "listen" for RC aircraft passes and announce the pass speed.  Furthermore, the app also can log and export all of your pass data via email so that you can review it later.  This works great if you want to analyze how modifying a feature of your aircraft has on its speed.  

 

Right now, the app works best with hi-RPM, hi-blade count propulsion systems (EDFs, pylon racers, pusher jets, and similar airplanes).  However, we are actively working on updating the app to "detect" more aircraft, as well as brainstorming some additional features.  

 

We would love some feedback from the community on features you would like to see in future builds, or any suggestions that you may have!

 

We also have a free computer version of the app on our website.  We are updating it constantly with new features, so check our site for updates!

Thanks!

 

Some general information on the app:

 

Turn your mobile device into an RC airplane speedometer!

 

Listen and fly!  RCSpeedo will relay airplane pass speeds vocally after each pass.

 

Fully featured pass logging and email export!

 

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!

  • @Troy This is a feature that we are possibly looking at for a future version.  Nothing is set in stone, but it has been discussed.  I will provide an update if we release a future version with this feature.
  • @Dany We do have a free PC version that you can try out that demonstrates the accuracy of the app.  Check it out on our site (www.rcspeedo.info).

    Note: AFAIK, this is not available to those in whose countries Android App Market does not yet allow paid-for apps.
  • COOL. I assume you are using Doppler shift to figure the speed. Have you looked at putting a sound source (beacon) on quieter planes. This would be awesome for Dynamic soaring guys. Would be nice not to have to point a radar gun at the plane.
    For those of you who don't know what dynamic soaring is. Its a way to fly gliders really fast like this

    Yes that is a glider (un powered airplane).

    seems nice... but before buying a $4 app I would like to see comparison tests with speed guns to make sure you are accurate (withing a reasonable margin)  how about a demo version for us to evaluate?
  • Good job guys !!
