GoolRC Second Generation Cool Throttle Linkage Groups Engine Sound Simulator with 2 Speakers for R/C Sports Car

Was simple to install. Comes with a “y” connector. One end goes in channel 2 where your esc would plug in the receiver. The other two ends go to the esc and sound unit. The nice thing is this unit has two speakers for better sound but you need to find room to mount them. You can always snip one off. 10 different sounds and the sounds come on at different rpms so you can find one for your drive style. I have a monster truck and I like the short course style sound this has. There are a couple that sounds like Diesel engines. One sort of like a muscle car, sort of. And on like a Japanese’s V6 drift car. You might have to use you imagination. Once the unit and speakers are mounted they sound much better vs bench testing it. The other brands are like 2-3x more expensive. I can’t justify spending that much for a sound box. This one is cool for me. I use Velcro to mount the unit and speakers so I can move it to other vehicles. It’s cheap enough you can get a couple though. I’ve only used it a couple of days. Can’t speak of the durability or longevity. In the video the battery is not charged all the way so if the unit doesn’t get enough power it will cut out and, “start up” again. Sounds like the engine stalled out, hahha! For the price I think it’s cool and adds another dimension to my RC truck.

No instructions but only has a volume knob and a push button to change different engine sounds easy to use. Speakers are a little big for certain situations. Plenty loud. Gas and diesel sounds. For the price it's a decent sound system for RC cars and trucks!!

Messed up my whole truck. Tried and it would rev up when i turned the wheels rev on right turn brake sound on left turn was trying to figure out what the problem was and then my truck just stopped working.. was nice and loud and liked the different modes i just wish it would have worked. My truck is a trxxas 4x4 slash by the way so i wouldnt recommend for a 4x4 slash.. piece of crap

I was Impressed with this Budget Sound Kit for RC Modeling Because this kit has everything that is required to install into just about any RC model. Likes: Easy to Install with all provided hardware Sound is Good for Variable Model's with Different Likeness of Engine's Volume Control is easy to access and level of sound Sound Button is simple to use for Different Variable's Comes with Quality 3M mounting tape, Ample enough for several mounting options Molded in Bevels and Mounting tabs on the Speaker Boxes for different applications Plug and Play with no worries of update adapters etc... Dislikes: (these are the reason's for the 4 star rating) Not Water Resistant or Splash Proof design. No Revving Sound in Reverse. Brake Squealing sound is not appealing for Reverse Motion. Sound is a little sketchy when full throttle is applied from a complete stop then catches up when model is traveling. Unit Speakers are Large and take allot of room with the Control Module. In short this is a good Budget Friendly sound unit Recommending for use in dry and non dusty area's for RC Model's...But not if you are planning on using this for a Moist/Wet and Dirt/Mud RC Model... Thank's For Watching Larry's RC Room = Having Fun Laughing Playing and RCing

Plugged the unit into my esc, turned on my remote then turned on the esc. It made the initial start up sound. It sounded good. I adjusted the volume, it worked fine. Toggled through the different engine sound options. Then I pulled the trigger on my transmitter and NOTHING. it doesn’t rev or anything else it just stays on idle. Believe me I tried messing with my throttle trim and whatever I could think of but NOTHING. It’s going back UPDATE: I changed my review from one star to theee stars because later on I found a ‘Y’ connector I didn’t see in the packaging. So I plugged it in( mind you there were no instructions included or I would have known about the other plug) once plugged in it worked fine. Most of the sounds are not that great. Maybe 3 or 4 were decent. I used it for one run and it actually adds more of a fun factor to the driving experience. It sounds better once the car’s body is on. It gives it a deeper tone and sounds pretty nice. I still returned it because when I was unplugging the unit from the vehicle, one of the wires pulled out rather easily and I just decided the quality just wasn’t that great.

I have been building custom RC trucks for customers for years. Most of them request engine sounds in the vehicles. I have used every kind of RC sound system out there, including the high end ones that require downloading sound files. In my last 5 custom builds (a 1:10 RC 10L pan car, two 1:6 custom New Bright H2's, a 1:8 Defender and a 1:8 CJ5), I have used the GoolRC sound kit (both from Amazon or from EBay). I would say this is the best-for-the-money sound kit for RC cars trucks, sized 1:10 or larger. Sounds are super clear and very loud. Out of all the sounds, I'd say maybe half of them are what most people would use. Setup is easy, no external battery required, and the speakers are loud and clear with no real static or popping.

It's easier to list the issues since I really can't comment on the way it may have been intended to work. -Product had no instructions and while I'm confident I connected it properly some may attempt this and cause damage. Then again, with no instructions it's impossible to know what do's and don'ts to observe to prevent damage. -When connected, device makes start-up and idle sounds and then starts randomly emulating squealing tires. This happens in every sound mode and in no way follows throttle and brake commands from the transmitter -DEVICE IS RIDICULOUSLY LOUD!!! When first plugged in the audio level was insane. I thought it may have been turned up by mistake when packaged only to find it was turned all the way down. This made the volume adjustment a completely useless feature. Lastly, this set-up will use a lot of room. The controller is about 7/8" thick, 1 1/4" wide, and 2 1/4" long while each speaker (there are 2) are roughly the same size except about 3 1/4" long. Most scalers will not have the room to chassis mount these and will have to find room somewhere on the body which means more weight up high.

Overall I'm impressed to be honest. What can you get for 25 bucks anymore that's decent quality and has everything in this line of product??? I do agree the higher end sound kits. Have better sound and better features. But for the price. I have zero complaints. The one thing I really don't care for is I wish it stopped after a short period of time when you stop your vehicle. Currently trying a few things on a 3rd channel switch to allow it to be turned on remotely. Yet maintain the sound through the second channel. Don't be afraid to buy this. Especially if you are upgrading something for like your children. Plenty light weight and cheap that if it breaks. It's cheap enough to replace. Just my 02 cents.

Sehr gut es macht grossen spaß mit Motor Sound zu fahren
