    Heli-Headspeed is a tachometer that measures the RPM of your RC model helicopter blades. For this purpose the blade sound is recorded and its frequency spectrum analyzed.

    It works with electric and nitro model helicopters with two blades. In nitro mode the gear transmission ratio must be entered.

    The app shows a small Quickstart guide upon first launch. Please read it!

    The measurement process is simple: a ) select the expected RPM range and b) click the measure button.

    In case of problems please contact

    Unfortunately Android market does not let developers reply to comments in the market.
