MrRCSound version 4.1 Sound System for Aircraft - MRS001

Do you wish your electric RC planes made more noise? The only scale detail missing from many electric RC planes is the noise of a real plane engine. The MrRCSound aircraft sound system adds a massive amount of realism to any RC plane and it is easy to install. NO MORE CUTTING HOLES FOR SPEAKERS! This system uses an ultra light 2.7oz - 3.1oz TT-25 transducer which effectively turns your whole plane into a speaker. Simply stick the speaker on the inside of the fuse of your plane using a little CA glue or Epoxy to hold it in place. This Aircraft sound system includes 6 different engine sounds which you can swap between at any time with the push of a button. The unit can sound like a Merlin, Lycoming, Continental, Pratt & Whitney Double Wasp, Daimler Benz 601 (BF-109), or a generic turbine. Also included are "auxiliary sounds" such as machine guns, cannons, a P-51 whistle, a Stuka siren, and various other sounds. There are multiple optional sound cards which may be purchased in order to add more engine and other auxiliary sounds. You select the sound you want to use by simply pressing a button on the unit. This unit also has a volume knob so you can easily change the sound level of the unit. This unit will fit planes 900mm and up depending on the room available in the fuse of your plane.

Also included is the "Airplane Finder" feature which allows you to locate your plane should you have a crash. This feature is only activated once you advance the throttle. When the sound unit detects no throttle input for 3 minutes, the alarm or "plane finder" sound will begin. 

WARNING - Connecting the sound system backwards can damage FMS ESCs; read the wiring instructions carefully.

Motion RC First Impressions

We had the whole system hooked up in less than 5 minutes. Wow is this sound system LOUD! We fired it up indoors and found the sound actually hurt our ears. Fantastic! We love how easy it is to swap between different engine sounds and we also really like the sound of the guns, cannons, etc. This system has the most fantastic startup and shutdown sounds we've heard. The realism is amazing. The systems volume control comes in handy when doing setup and testing. More videos and flight tests to come soon.

Connections and required cables

We recommend using your flight pack to power the MrRCSound sound system. The unit includes a JST power connector and we recommend tapping off your main power connector. If your plane has a T connector, we recommend using one of our "pass through T connectors" with a JST connector tap. There are 4 sets of pins on the unit. These accept 4" male to male servo cables or 8" male to male servo cables which will connect to your RX. These are labeled "Servo 1-4”. Servo 1 is the the main engine sound. Servo 2-3-4 are used for auxiliary sounds such as guns, whistles, and pilot chatter. You will very likely also need a servo Y cable for the throttle channel
