The Mr RC Sound System

The Mr RC Sound System can be simply installed in your RC electric flyer! The smallest and lightest sound module, with authentic engine sounds, is now available.

Now speaker less!

Please note that MR RC Sound units are no longer available!

Mr RC Sound V4.1 unit

Now you can really wow your club mates at the flying field! The Mr RC Sound System, is small and light enough to install in your RC park flyer! Models with wing spans as low as 31 in. (787mm) can now sound just like a full size plane.

Many flyers think that gas engines sound more authentic than a four stoke, now you can win that discussion by being 100% scale!

The modules are hooked up, via a Y-harness, to the throttle channel and the sound features authentic "tick-over" and start up sounds as well as the full throated roar of real airplane engines. Sounds are fully proportional to throttle stick position and also feature a full shut down sequence.

Choices for sounds currently are Lycoming, Merlin, Continental, Daimler Benz 601, Pratt and Whitney Double Wasp, a generic turbine and more. Other sound options will be added later. (See below for more details)

 2.4GHz radios are recommended as the older 72 MHz RC radios are prone to interference from the amplifier module.

As well as the awesome engine sounds available, gun and cannon sounds are also possible along with synchronized LEDs. So now you can strafe the runway at your local club field!

Mr RC Sound TT-25 transducer

Latest News - Now Speakerless!

The latest technology for the system is the TT-25 transducer. By using this unit no speakers are required!

The transducer is peel and stick mounted, to the inside of the fuselage and the whole fuselage becomes a speaker.

No "cheater" hole is needed for the sound to escape and the sound volume is comparable and in some instances exceeds, the sound output of the Max2-SPL speaker previously used.

Aspire Module

The Aspire module is the latest technology, with quality sound and more features to make your model even more realistic!

The Aspire produces true scale sound from start-up, through idle and up to full throttle.

I love it when I taxi back to the pits, after a good flight and reduce the throttle to the stop position and hear the "engine" spit and pop to a standstill!

Extra items required

  • A Servo "Y" connector may be required, if a computer radio is not available.
  • A power "Y" connector, with matching connectors for your system.
  • That's it! Everything else is included with your unit.

Installation of the Mr RC Sound System

Full mounting instructions are included with every system, but here are a few notes that may help.

  • Keep the unit as close to the CG (balance point) as possible and be SURE to check the balance point prior to flying!
  • Soldering is required to make a power "Y" connector. A normal "Y" connector is used to connect the RC sound system to the throttle channel of the receiver. Note that adapters to fit the most popular connecters are now available! Click here for details.
  • If you use a computer radio then a spare channel can be used and mixed with the throttle channel, then no radio "Y" connector is required.
  • Note that the system uses the LiPo battery of the airplane. Power draw is at a minimum, so flight times will not be affected dramatically.
  • Take a look at the above video to see a typical installation procedure.
