- เผยแพร่เมื่อ 5 พ.ค. 2022
- I've installed a couple of the Model Sounds Inc. sound systems into my Legend Hobby A-1 Skyraider RC Warbirds and so thought I'd put together a quick video on the installation. A sound system is a really cool feature to have and on the ground it sounds great! There are some things to consider for getting the max sound out of the airframe which I touch on in the vid. So, what do you think, does it sound real?? #SoundSystem #RCWarbird #A1Skyraider

To increase sound volume, you need to builds an air tight chamber behind each speaker. The sound waves from the front and the rear of the speaker cone are currently trying to cancel out the each other. Try this, you will be amazed at the increase in volume. I have been installing sound systems in model locomotives for many years. Larry
This. Speakers will also have a "fuller" sound with better bass. Doesn't even have to be perfectly airtight, just a baffle to block some of the front and rear sound waves mixing will net noticeable results. Both speakers can use the same enclosure if they are in phase.
Quickest bet is to buy sealed TV speakers
@@kingcosworth2643 Great idea, they also tend to come in oval shapes that will be an easier fit for most fuselages.
I've also been pondering using exciters/transducers instead of speakers, this will turn the whole airframe into a speaker. Should work particularly well with hollow composite fuselages. Also takes up much less space than a speaker.
What if he reversed the polarity of one of the speakers? that way instead of both pushing and pulling against each other, they are working in tandem pushing air left and right?
@@krupert8355 In a completley open baffle system like this, it wouldn't make much difference. I'm not even sure if it would be slightly better or slightly worse, although it would be an easy enough experiment to try out. The cancellation occurs mostly at low frequencies.
WOW. I religiously dislike the trend in "full size" electric cars but absolutely LOVE THIS in this implementation. Immediate SMILES ear to ear. Good job. 100 points awarded.
3D printed engine looks awesome, love the sound system.
That's so awesome. i've always wondered why we put sound systems in our trucks and fly airplanes and helicopters silently. When asked, a pilot friend once said, why should you do that. Now I've shared this video and he's hooked
Very nice and solves what to me is the biggest problem with RC in general and electrics in specific... The sound. Thanks for sharing.
Close your eyes and your right on the tarmac with those beauties. Great job all around. Me, I like it in the garage. Those planes were loud as hell. Love the 4 blade prop.
Awesome setup! And thanks for the shout out! The radial looks great in there!
Thanks and thanks for making the model available for us! :)
AWESOME!!!!! :D
@@Thercgeek My pleasure!
That's so cool! Next level!
I love this set up!
Awesome project! Thanks for sharing.
The last sound of the plane flying, sounded really nice. And came through really loud. If it was that loud I think it is great.
That beast sounds awesome, great job!
Thanks!
LOL This is fantastic ! Good work !
Beautiful paint work to. Your videos gives me the drive to fly and learn
Reading that makes me happy, thank you!
Looks and sounds awesome!
Wow amazing sounds
That's fantastic!
The balsa wood gives a nice resonance which helps with the speaker sound. When we tried it on a foam plane it was hilarious and a little muffy here and there, but it was a fun experiment
You had me at Skyraider ❤
WOOT WOOT!! ANOTHER AWESOME VIDEO CHRIS!!! :D
Thanks brother!! 😊
They've even got a sound clip with independent controls for the P-61 Black Widow! 👏🤓
So Cool. Love it.
Thank you! Cheers!
Super cool
Great work !!
Thanks a lot!
Boy, the toys they have for children like you are incredible. In my time the best we had were control like... brick on a stick... it's too bad real children can't afford these toys...
That thing sounds so rad
It's pretty fun. :)
Engine sounds very accurate at idle. I have flown an actual A-1E Skyraider. Even with a flight helmet on, it is the loudest piston engine aircraft I have ever been in.
Oh but what a sweet sound!
WHAT??? A little joke.
Every time I see a foam T-28 fly, I listen for the lovely sound of a radial engine...
Haha
Sounds great to me!
Well done!!
Thank you!
good sound , well done.
Thanks! 😊
Very clever idea! At the beginning of the video I thought, oops, someone spent a lot of money on a real radial engine...
Wow love it, play more
Love it! Way kool.
Very nice aircraft
Thanks!
Good job on the plane love the sound. Need to find one for the f16
Thanks man! Model sounds does have different sizes and can be used for jets too. 😊
I'm dead jealous,envy you..liked n subscribed.
Very nice. Print a Cowel (or drill what you have) with small holes where the speaker is located, and it will be much louder. Aerodynamics will not be adversely affected.
Nice, i use realistic sounds on my RC Tanks. Real engine Sounds on electro RC Planes or whatever makes it even more fun.
Awesome
As someone into rc and music amplification, now I want to make a kit build to have sound resonance and reverb. I’ve seen 2 watt guitar amps with tube preamps run on batteries. It’s just more of a weight issue at that point
That sounds awesome! What about some subtle holes or mesh in the cowling to let the sound out without messing up the looks of the cowling too much? Just a thought.
Sound panel speakers coming off the wing foam would be awesome. I still think you should run it off of tubes for full retro points.
Fun fact Russian jets still use some tube technology as it’s emp resistant
Your plane looks fantastic! I really love what you did with the dummy radial and it sounds great too.
I would be happy if I could keep my foamy Cessna in the air. Trying to teach myself to fly is expensive. I got a great simulator that even had my exact plane, but I kept crashing & after six months we had to upgrade our computer. Guess what, the simulator no longer works. It needs an upgrade too. I haven't even tried to fly in several years. It is embarrassing to spend time & money on a plane only to crash it 7 minutes after you get to the park.
Teaching yourself to fly is pretty challenging. I would highly recommend getting connected to a local rc club as they usually have instructors who can help folks get started and gain proficiency.
Add Bullet Holes for sound. Just COOL
Haha, I guess that’s one way to do it! 😆
I find the transducers are really good on foam but the couple of balsa planes I have tried not so much. I think speakers are the way to go on balsa, light ply air-frames.
I appreciate your comment. That’s kind of been my understanding, but I’ve never personally tried the transducers, so that’s a good data point to know.
Sounds awesome but if you use some dynamat foil behind the speaker way loader and richer 👍✌️
Beautifully done. I noticed in your links it looks like you're using a 12ch rx. Curious to know how many channels you used for this setup?
I’m using it for the power safe redundancy mostly although I am using 11 of the 12 channels. I have both flaps and elevators on separate channels in the configuration plus the tanks and centerline bomb drop are separate to each other as well.
Needs some smoke when starting up! Awesome job
Like the sound system. Much better, than listening to the "lawnmower" sound in the usual prop powered RC models, kind of breaks the "realism".
This is so cool! I'm curious, how difficult is it to manage the cg (weight & balance) of these modified models? What is required?
The cg is managed the same really. I placed this all in the nose knowing the model was going to need weight forward of the cg. The result was not having to add any additional weight to get the cg where it needed to be.
A Boeing 707 with prop plane sounds would be hilarious 🤣😂
Haha
Is there a way to have the same module but with customizable sounds effect of my own? If not is there anything out there that I can use? Thank you.
put some vent in the cowl.. sounds killer
You did a great job with this SkyRaider, is it available yet? Most of my prop warbirds are the 1600-2000mm foamies so always used the transducers. Recently built out the Extreme Flight FW 190 "Red Tulip" and after seeing this video when it came out, wanted to try the Model Sound speakers. Unfortunately, the 4" speakers were too large, went to the 3" speakers but they're waterproof and much heavier. Still flies great and the sound is far superior including the 13 & 20mm cannons. Did ultimately put openings for sound under cowl and mid fuselage after David kinda threw you under the bus and said "don't follow Chris" when I suggested if no holes were good enough for you so I would defer to the Master! 🤣 Don't feel bad though, I suggested some reprogramming on his start up sequence that I had to do with a Castle ESC that didn't work right using his method and he told me to basically go fly a kite. 😉
Thanks! Yes, these birds are now available. Legend just shipped out all preorders recently. I have a hard time not have a pristine looking model, so drilling holes in the cowl for the speakers just wasn’t going to happen, haha! Ideally, the speakers would be set on the bottom of the wings facing downward with screens over them vs in the cowl actually. That would be a better way to hide them too.
You should have used two part epoxy for gluing the blocks for the sound system. CA glue is brittle, and it will crack. I have a lot of experience with this.
I’ve bout a kit from him and was going to install it on my A-10, but then realized that no one was really going to hear my gun sounds except statically. The kit is still on the shelf waiting for a home.
Interesting
Awesome! Just need to add a lil puff of blue gray smoke @6:47 Hahaha! On a side note, where are you flying out of?
I flew this one out at the Pomona valley flyers near chino airport.
@@Thercgeek Nice, for some reason I thought it looked near Santa Clarita (I grew up there) I now live near Chino in Ontario by ONT. I'm friends with Mark the owner of Threshold Ind @ CNO, so very familiar with that airport. Thanks for the reply!
Where do you place the subwoofer?
I honestly think that despite how sweet scale radial engines sound, a dedicated sound system delivers a sound more true to a full scale radial engine.
They definitely can if executed properly. The sounds are based off of actual recordings from the aircraft, so that definitely adds to the authenticity.
I have seen systems where the modeler mounted the speakers in the bottom of the wing.
That is the ideal installation with a fine mesh covering the speakers.
I notice you 3D print so how about making some perforated baffles, same size as speakers and incorporate them in the cowls. You can then paint them as original colours.
The ideal install would have been to install in the wings facing downward with a screen mesh across the speaker. This was just easier, haha
Great Video Bro, One of your better. Now what these sound systems all need is a way to get the Electric motor to turn over slowly thru 12 to 15 blades (like the full scale big radials) with the Sound of the starter whine and popping of Individual cylinders firing. That would be realism to the max. Now what about the Big Engine SMOKE on start up??? Think that would be way too much to ask for?
Thanks man! The outrunner motors tend to start right up. However, gwith earboxed inrunner motors you can coax into a slow start up due to the drag of the gearbox. I’ve thought about ways to puff smoke and such, but that’s about as far as it’s gotten, haha! That would be really fun to try to do.
@@Thercgeek I'ce thought of placing a small electric motor with a rubber wheel that would turn the OUT RUNNER slowly at first 10 to 15 seconds then engage the flight motor. But ain't gott'n Round-to-it either.
I might be wrong, but I think if you reversed the speaker leads on one of the speakers the sound might be improved. My reasoning: the two speakers would be in phase if they were pointing in the same direction, but since their directions are reversed they are 180 degrees out of phase, producing some sound cancellation.
was thinking if replaced these drivers with sealed mids. The lows would improve, and provide some feeling, and the lows of the exhaust note. However it sounds awesome love the addition of the sound effects
For me, the talk nerdy t shirt made this video.
It’s one of my go to’s 🤣
@@Thercgeek I told my fiancé about it. She laughed! I have to source one out now:)
Hole pattern in front of speakers ! Small enough to not mess up air flow !
The ideal install would be the speakers being in the wings pointed downward covered by screens. I didn’t want to put holes in the cowl for aesthetic reasons.
Would it be possible to make the cowl, the speaker...attach the transducer directly to it ???
That seems feasible. I know someone who basically did that with a whole balsa fuselage.
What about making the surface of the fuselage or wing a speaker. Back in the 1970's Radio Shack sold very flat speakers that were installed behind wall panelling. Just a though. Nice job and sound BTW. Love the Skyraider aircraft.
Yes, that is definitely an option. Basically build a speaker box and/or make the airframe a speaker box essentially. You would still need openings for the sound waves to exit though for the loudness. That’s where an exciter setup might work better here vs the speakers.
@@Thercgeek I was thinking more of the skin of the aircraft being the vibrating surface. Maybe the underside of the wing or fuselage. Bee Safe
Ah, ok. I’m pretty sure that’s what the exciter setups do.
How about some cowl flaps to improve the sound channel?
That would help, but ultimately the openings really need to be in front of the speaker.
I have the same plane, scale 1/5 100 cc boxer engine, nou sound system needed😊
Haha, indeed!
Chris l really like how you are trueful with the products you show and demonstrate, lm thinking of buying model's sounds lnc.sound system, l will drill small holes,,but l need to know will it drain alot of battery, l fly seagulls models p47 wicked rabbit 81" wingspan on 12s lipo,160KV 160 amp esc,and do you recommend 2 speakers, thank you Chris for your time, Brian Broady
I really would like to hear it while in flight, can't wait to be able to order sound system
, also waiting to see your latest project flying
The system doesn’t draw much current at all. In a more correct installation with proper venting, it should sound even better. The ideal install is somewhere more in the wings with the speakers pointing downwards with a screen cover over them.
That's great and all doing all that detailing but one crash and it's all over with
I'd rather be flying LOL
All part of the game
👍😎👍
Will the hot glue hold up over time?
No issues thus far. I did the same with my bubble top Skyraider and it’s held up fantastically for a couple years now.
If it’s Geek approved it must be good 😀
Haha, yes! 😄
Model sounds Inc is no longer selling systems. Do you have any recommendations for other systems. I am building a P51 pedal plane for my son and would love the warbird sounds. Thanks-Chris
Yeah, that was a bummer about MS Inc. the only other company I’m aware of is Mr RC Sound, but I don’t have any experience with them.
There should be a way to rotate the Lectric motor at about 30 rpm so it sounds like an R-2800 with the starter whining and the cylinders popping till they catch and fire off OH should be a Cloud of residual Oil Smoke too. Possibly a small electric low rpm motor with a small rubber wheel that presses against the outer shell of the planes the main motor when the power is applied to the little motor as a starter would do.
Plus for the Skyraider, a pool of oil on the ground below the engine too! 😆

What kind of hot glue do you use?
It’s just the craft stuff. I figure it’s all more or less the same.
👍
👍🤟🤟
Does anyone know of any other companies that sells sound systems for jets MrRC apparently no longer sells jet sound packs
Two speakers in series means that you double the impedance, which means you half the output ... what was the impedance (ohms) of the speakers? Do they have sound systems for helicopters? And what does it sound like in a fly by? You didn't show a fly by...except for the Corsair...
Yep, model sounds has sound systems for most all vehicle types including helis. When installed in a way that allows the sound to escape (unlike what I did here), it should be quite audible flying by. Since I have the speakers closed up in the cowl, it’s not super audible in flight other than on final approach at low throttle settings.
Why not cut some slits in the cowling in front of the speaker and then add some mesh netting inside for aesthetics?
Yes, that is an option. The installation here is far from ideal. The ideal install would be in the wings facing downward with a screen mesh covering the speakers.
@@Thercgeek that would sound insane with the resonance coming off the ground
The front row cylinders are out of phase. Lower cylinder needs to be straight down, for number 10 cylinder...!!!!! So the rear row will have the #1 cylinder would be straight "up".....
Whoops! 😬
No worries!!!! Thought you may want know for future reference. I was in overhaul on the Wright R3350-26WD engine the Skyraiders used.........
Good looking model !!!!
How many speakers are there ?
There are two speakers in the cowl mounted facing out left and right.
I Was hoping for a high throttle screaming dive.
I mention it in the vid, because of the way I installed it without vent holes, it’s not very audible in flight.
Grrrr I do not have a 3D printer. I sure would like to do something like this with my Gator RC P-47
Well, I do custom printing for folks and the model can be scaled to any size really. Shoot me an email if you'd like to discuss more.
@@Thercgeek I sure will thank you very much
never seen speakers hooked up in series
Common in car audio, changes the resistance of the system
Right, it’s about ensuring the proper resistance for the input voltage. At least that’s my understanding.
Sounds exactly like a Heng Long rc 1/16 tank.
Haha
🤫 Now for a video doing a 👉🏻fly-by👈🏻
There’s that an more here 😆 th-cam.com/video/_-n-r9lI5NY/w-d-xo.html
make holes small front the speeker... ! evident no?
Yes, that would help considerably since sound is directional. The ideal install would be to have the speakers in the wings facing downward with a screen mesh covering them.
All you need now is some smoke on engine startup and you're authentic
Try a silver Lemay cloth on a wire frame for your cowling the sound should go right through it just like a house speaker nice job. That sounded nice
Can you get a Machine gun sound ?
The model sounds sound system actually includes that with it but I don’t have it setup.
All we need is the smoke and we’re ready to go.
The very best sound system is an actual engine! I still prefer glow over electric for the realism and the fact that wiping it down after flying gives it a nice shine! Electric loses power as the weight remains the same. Glow loses weight as the power stays the same. When electric makes it's way to General aviation, I believe that fact alone is going to kill a lot of people. Imagine trying to fly at gross weight over the mountains as power begins to decrease! Scary thought! You will have to decide who to throw out!
Yeah, as I mentioned you'll never be able to replace the sound of an actual engine, especially a Moki radial, but it does well for what it is. I will say, I don't miss the sound of glow, but I do miss the smell! ;) Electric in GE is a whole other story though. When you look at sizing an all electric man carrying aircraft, it really doesn't make a lot of sense as the battery weight heavily drives the design since it's a HUGE part of the overall weight.
Good idea, sounds to toyish. Have long ways to go. Should have headphones for pilot, 100 times more realistic
Haha! It’s really hard to replace that true radial sound, but it’s not bad and there are things I could do with the installation to make it better.
You Just need smoke on startup now
oof, so heavy though.
