PYFOREESS Dual Engine Sound Simulator System for Axial SCX10/SCX10 II Traxxas TRX4 Axial Wraith (Dual+Engine)

I’ve installed a few of these over the last couple of years and have been very happy with them - great sounding and good installation process.

Fatto molto bene

I was really skeptical about this at first, and I kind of bought it on a whim after seeing some videos online. I thought that sounds would be a little silly from an RC car. I decided to pull the trigger as I just got the Mercedes TRX-6 and had the perfect spot for it. Well this thing is AWESOME, my TRX-6 has a HobbyWing Fusion Pro in it and it works great with it. I needed an adapter that had male JST plugs on it so I could run it with my lights as well. My splitter was only female JST’s all the way around so I had to get creative, but I managed to get it working. I ran it on 2s but it says it can go up to 6s, just needs to be turned down. I have it turned up one or two and it’s pretty loud then, and can get louder. I also had a little servo extension from the receiver for the Fusion, so I just threw the splitter on and plugged it all in, along with the JST power plugs and it worked right out of the box. I ended up using some Velcro to hold it in place even though it comes with mounts and double sided 3m. I stuck it right in the front battery plate on the TRX-6 and it’s a perfect fit, along with adding some weight to the front. All in all, it’s very nice. I was going to get the smaller one but for 5 bucks extra I got this, and it’s worth it. Haven’t used the program yet but I’ll be doing that soon and hopefully I can tweak a few things on it.

A+ seller. Amazon customer service is top notch. This machine now comes to life and roars. Many parameter settings and customizations available via the included software. For me it’s like trying VR then going back to pancake mode. You just can’t without it anymore. I’ve tried a couple of different cheap versions and they just get annoying. This one idles and doesn’t appear to have that awful looping sound effect. Don’t judge what you hear on videos just try it. Your miles may vary due to placement on rc vehicle but it roars.

I decided to give this a try and tossed it in my CEN Racing F-450.. I have to say It makes me giggle like a kid hearing the truck sound so real. Everyone who has heard it is blown away. The options for different engine sounds, throttle sensitivity, idle length etc.. Are great. I ended up buying another for one of my crawlers and another for my Fazer Mk2 kit build..all with sounds to fit the vehicle type and all sound great. Easy to hook up and easy to move between vehicles if you want to use in more than one. My only con for this is the software you download and website you use is Chinese and asks for a lot of permissions, one of my computers didn't like that/allow me to even install or open it. I ended up putting on an old laptop I have, who knows how secure having that program on my computer is, but I have nothing on that computer should there be a virus or something from it. Overall I think the little bit higher price tag of this brand is worth it over the cheap ones out there with how much customization you have. 100% recommend
