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 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.
This is my old Marvel-Craft H125 700 with RVE DUBHE mechanics, I switched to from SAB Kraken 700 and it's much lighter. I used this very easy to fly platform for my first Vantac 007 RF TW/X20RS configuration. It's very important to use the FrSky recommended servo order. I had to change it in my radio which was configured for MSH for Futaba order. I still have a long way to do before it's as...
This is my old Marvel-Craft H125 700 with RVE DUBHE mechanics, I switched to from SAB Kraken 700 and it's much lighter. I used this very easy to fly platform for my first Vantac 007 RF TW/X20RS configuration. It's very important to use the FrSky recommended servo order. I had to change it in my radio which was configured for MSH for Futaba order. I still have a long way to do before it's as consistent and easy to fly as the iKon2. The biggest hurdle is access to the mechanics inside the fuselage to configure the FCU. This is my first flight and it shows. The heli is all over the place but at least I did not crash it. I will spend the winter months working on it. Head speed is 1150, Heli-Tec 680, Hobbywing 200 (for ballast and easy to configure in RF). Integration and telemetry work perfectly. I had to change to 110 tail blades because of the low head speed and tail authority loss.

TY Michael. I'm a bit disoriented here but I like it. There are very few topics I can post on mainly because I create stuff lol. But I love sites dedicated to scale helis. There's a huge hype for RF with 3D guys but I find it awkward to configure for scale flight. Pod & booms have easy access, not so for scale. But it's genius new tech everyone can afford and I plan to do the same with it as with MSH which is still my platform of choice for scale. There are way too many toxic urban legends in scale for my liking.
RCPilotConverting the Roban 470 Cobra to a FrSky X18 and TD R6 ReceiverThanks for stopping by! I'm honored to have the opportunity to share what I've learned while converting my ready-to-fly Roban 470 Cobra to work with my own radio system. I'm not a very experienced RC helicopter pilot, an
A Complete Step-by-Step Conversion Guide — From Installation to Successful Flight Testing
I am looking for a Emcotec 70v 100/200a Switch. If you have something for me, let me know.
Does anyone use Multiplex Safety Switch Twinnbatt pro(M6)? I am trying to decide between the Multiplex and Jeti CB210. But the Multiplex has better numbers(35Amp).
Jeti only 15Amp.
I would like to power my receivers and servos with 2SLipo.
I will use HV servos(5x). Helicopter is Vario 1/7 Bell 212.
Curious what others use for magnetic power switches (if any)? What do you use to monitor battery pack mAh total usage?

What I have done for my Lama is simply to add two tiny wires in parallel (not in serie as usually) to snif the current voltage and this is connected to the external telemetry voltage input of the 7008SB.
At some pre-defined low voltage I know it's time to land and there is approx. 20% battery left under load (not using old Lipos).
Never had an issue doing this cheap way and countdown timer is enabled, whilst I know that reading the tension in serie is best (look after the old IISI Cockpit V2 TXEs options about measurement methods).
Otherwise I use PowerBox with telemetry (2x2500 Pro).
I tried to post this in Buy & Sell but it doesn't work so I am giving this a try. Please see photos.
Is there a way to post something like this in Buy & Sell?

You can certainly post something like this in the buy/sell area. You can also create a “wish” and if someone posts one, you’ll get notified immediately
i would like to expand my understanding of the differences in servo settings, specifically the 760 uS vs. the 1500uS i understand the #'sare for centering. But I've been unlucky in my search as to a clear definition to what those #'s specifically mean and do.
New to SHP. Stumped & need some help. After 10 years I am jumping back into RC Heli's. I last left off with a fully operational TRex 600 and a large drone. I purchased a Roban 700 AH-64 and have the mechanics ready & electronics installed. System - Spektrum ix14 trans & AR8000 Rec'vr, I bought the Motion RC recommended electronics, Castle 160 ESC @ BEC, 3 MKS DS1220 Servo's, 1 MKS HBL 980...

System - Spektrum ix14 trans & AR8000 Rec'vr, I bought the Motion RC recommended electronics, Castle 160 ESC @ BEC, 3 MKS DS1220 Servo's, 1 MKS HBL 980 and 2 Admiral 5000 mAh batteries. I hook up the esc and the motor operates as programmed. However, the servo's will not function at all. I programmed the Castle ESC to 6.6V & tried 7.6 volts, still nothing moves or makes a sound. I have tried an AR14400 Rec'vr as well with no different results.
Would appreciate some advice on how to get the servo's functioning.
Thanks A
Ah you might have hit on something most servos operate on 1520us frequency are the servos you have 760us ? They won’t work if so unless you tell the recv/ FBL unit so. Ask me how I learned that one lol.
Does anyone know when and maybe where the NEW Flywing H1 and GPS is coming out? This is the one that has NO minimum distance between the 2 units
why cant i find, and where can i find the max amp at stall for servos?
Need help. Have a 900 size Vario R22. It flys great but am having a problem. Burning up tail rotor servos. On the third one now and at this point it wont last long. After a 7 minute flight the servo is hot enough you can blister your finger (if you could hold it on it long enough) . Shorten the flight time to 5 minutes not much difference, still hot. The cyclic servos are just fine. What we...
Need help. Have a 900 size Vario R22. It flys great but am having a problem. Burning up tail rotor servos. On the third one now and at this point it wont last long. After a 7 minute flight the servo is hot enough you can blister your finger (if you could hold it on it long enough) . Shorten the flight time to 5 minutes not much difference, still hot. The cyclic servos are just fine. What we have done so far in trying to fix the problem. Linkage operates freely. Checked the voltage coming out of the FBL ( same as the cyclic ones) it is within specs. Servo is a HV up to 8.4v. Double checked the programing in FBL. it is set at 760 pulse and 500 frequency.( servo specs are 760 pulse and 560 freguency but Axon Fbl only goes to 500) Have run out of what to check or do next. I know I can't keep replacing servo at 2 or 3 flights,
Just a few photos of my AS315B Starwood Lama Build. I will post a build series in the next few days to show how I got to this point.

Clean install, Rene!
