I remember someone did this with a F1 and a hacked Konami F1 sound module, but this setup is much simplier. I used a VRC USB adaptor (www.virtualrc.com) to convert the radio signal to joystick control. Basically it is a 2nd receiver with the same crystal that gives the throttle position to the PC.
PC side, I used the Jambient free software witch changes the pitch of any wav file using a joystick. Now I am cutting some wav loops from real car sounds found on internet, basically just a loop from gear change to next gear change ;) I already edit some to go with my 360 Modena, F40, Mustang GT, shelby Cobra (weird!) and... Mc Laren F1! I will post a new video soon with the car running with sound.

very clever. I'm looking forward to seeing the video of a car running with sound. Should be quite interesting.

Here is some test with my Cobra and the sound of a real 427 V8 :D

It is not easy to setup on the track, changing gears is OK but the difficult part is everything is faster than in real life with a Mini-Z, for instance changing 4 gears in a 3 sec long straight :rolleyes:

man that is just sweet! I would love to see it on a track with gear changes and all. Gearing up for the straights and down shifting for the corner :D

kyosho once tried to sell a seperate device to do this, was not supsoe to be IN the car though, but hooked up to large speaker next to track.

Tamiya actually has something just like this.. It's available for their 1/14th scale RC tractor truck line.. I believe it's called the "Diesel sound generator", or something like that.. It has all the diesel truck sounds, and makes driving noises while the truck is moving, it even beeps while the truck is backing up, and makes sounds for the air-brakes when you hit the brakes while driving the truck.. It's pretty cool, but it's pricey, It's about 150 dollars just for the sound-unit, and it includes a small speaker that mounts in the cab of the truck..

It's a Multi-Function Unit (MFU for short)... they also sell it for the F350 High Lift at a nice high price of $200.

However, it also controls the lights, so, if you take a left turn, the left blinker (aka directional) will blink.etc, they have an MP3 input jack, and I think they also act as an ESC, so that should account for some of the price.

Great job.

Guys, I'm not interested in the lights, back up alarms or diesel engine sounds, I just want THAT 427 sound!!!! :D That is just too cool!!! I'm also a musician, so amplification is not a problem. This site is just too cool. :cool:

Sooooooo, how exactly did you do it?????

Hi Boomer!

I am glad you are interested with this.
I kind of lost interest in this setup because the sound actually does not come from the car itself but from speakers around the track.
Next, I will try to build an inboard module if I can find the hardware using the Tamiya sound module principle, this should improve the realism if the sound comes from the car.

What you need for the setup as seen on video:

Hardware:
An AM receiver with cristal at same frequency as of the mini-z.
A USB game adaptor such as this one (http://www.virtualrc.com/game/games.aspx)
A laptop with soundcard and speakers

Software:
Jambient: free download here (http://www.download.com/Jambient/3000-2170_4-6582541.html)
A looped wave (.wav) file of 4-5 second sample of a 427 engine at neutral idling (I found it on internet along with many other sounds, Lambo, Ferrari, etc).
You can edit this short sample from a longer recording found on internet using any sound software.

This is how it goes.

When you control your mini-z, the second (stand alone)receiver sends the throttle signal to the software through the VRC USB adaptor wich emulates a "joystick" input. Jambient interprets the joystick input and changes the pitch of the wavefile accordingly, all you need is to setup the software so that the wavefile is "idling" when the throttle is released and at around the desired pitch at full throttle.

Thanks Leonen! Maybe using a train smoke module ;)

Oops, forgot...

Cost:
VRC USB adaptor: $40
AM 2 channel receiver (Futaba) $20

Fovea You are Awesome!!!! Thanks for sharing that info!!! I don't know if you heard of RAM rc lights and sound, but he does make a 2" speaker and board that go on 1/10 scale cars, I don't know if you could use his parts, but it may be worth a look. It costs around $50 US. you can find him at
http://www.ramrcandramtrack.com/

Thanks again!!!

Thanks for the link!
I may have found another compact module to be mounted inboard: Benedini (http://www.benedini.de/Home_E/Products_E/products_e.html) watch for the TBS micro. It can play different wav sounds depending on the position of the throttle. It also needs an amplifier + speaker but I intend to borrow the small speaker from a cellphone (those that play MP3's nicely). To load the wav files a loading module is required, this makes for an expensive system, you can watch it used on a plane model: P47 (http://www.youtube.com/watch?v=ua8vvwn59q8&watch_response)

Cool, keep us posted!!! For now, I'm going to build your setup. But, if we can get it small enough to fit into one of the cars, heck, why not!!!! :D
