Default Nitro Tuning Table

This was an idea thought up by my dad and built by me. Basically, it's so you can tune your truck under a load and don't have to run it up and down the street. What do you think?

The only problem I could see is you need air flowing over the engine head or if you don't you will overheat the engine and damage it. You should have a large fan blowing across the truck.

That was just the test to make sure it worked the way I thought it would. You're right. There will be a fan there during future use!

i like it
you may not be able to get a perfect tune on it but it sure should get you in the ballpark
in addition to the fan you might consider a way to increase/decrease the roller resistance
might give more of a real world feel to the low end for lsn tuning

The only problem I see with adding resistance to the rollers is that it may cause unwanted wear on the clutch, etc.

no more so than a normal take off on a hard surface would
and, i'd think, it would give you a better idea of the lsn tuning
wouldn't have to be a lot extra
just enough to simulate the initial load on the engine/drivetrain

It's kinda hard to see it in the video, but there is some initial resistance. There is almost no free-wheeling when you let off the throttle.

It was his idea, I made it. As far as making another one goes, I need to how hard it is to get some more rollers or figure out something else to use in their place. The rollers I got were a hook-up from a friend of mine.

Sorry man I read it wrong. LMK if youre going to make more. I always like extra cool stuff that takes up space in my shop.

No worries. I've definitely thought about mass producing them. I just need to figure out if it's gonna be cost effective.

Just an FYI for those interested in making their own...

This setup is not so much something you fabricate on your own, unless you have a lot of money and extra time.

I remember from working for UPS several years ago that this is the same exact setup they use down the middle of their long trailers to aid loading and unloading of the trailer. For example, instead of unloading the trailer box by box and walking all the way to the end where the conveyor belt starts, the unloader could simply roll the boxes down this track. The conveyor belt was then positioned at the end of these rollers near the back of the trailer and would pull the boxes into the sorting system as they came off the rollers.

So, in short, if you'd like one these for yourself, go find some abandoned trailers and see if they have a roller frame up the middle. If so, grab your sawzall and/or toolkit and remove a part of the frame...and voila, you have a R/C Nitro Dyno.

Or, you can purchase your own by visiting a website like this: [link=http://www.ashlandconveyor.com/category39_86/index.html?page=1&sort=2a&osCsid=7ef63c923c6f0d4b8cb93076a7868de9]Ashland Conveyor Products[/link] or checking to see if you can acquire one on eBay.

cheap rollers people , painters roof roller ! Add bearings ! At 3 bucks each you can afford to bearing them !
Nice idea, how do you get the %age of resistance right though, a revo on the rollers should be pushing the weight of a revo through the rollers, it also doesnt take into account wind resistance on top end tune, but its an interesting idea, well done.

Or, this:

F = (C * 1.8) + 32

C = (F - 32) / 1.8
