BEIER-ELECTRONIC Sound Systems

I have been using sound systems for many years with great results. I had one of my models at a show a few years ago and as I was spooling up I heard the announcer saying what a realistic turbine I was using, he was very surprised to find out it was an electric model with a sound system. I used the older ModelSoundsInc system for years but they went out of business and BeierElectronics, a German based company that has been in the sound business for many years decided to make their system compatible with RC Helicopters. They offer the addition of an amplifier which allows you to hear the authentic rotor sound in flight of the selected full size helicopter.
I have included a video of my Starwood Lama which you can see in the "video section".
BeierElectronics offer many different helicopter sounds to choose from as well as the option to purchase the individual components needed to fit your project. I use two four inch speakers, USM-RC-3 sound module and amplifier in my big models. You can choose the size and number of speakers or use of the amplifier to fit your project. Their system allows you to personalize your model with ATC voices, guns sounds and other sounds if desired. You can power the sound module from your receiver battery or use a seperate 7.4 as I do. I power the amplifer with a small 1000mah 6S for many flights.
You can reach BEIER-ELECTRONIC.DE outside the U.S. or contact HOBBYCONCEPTS.NET in the U.S. if you have questions you can reach out to Bob Jacobsen at HOBBYCONCEPTS and he knows EVERYTHING about the product and can answer any of your questions.
