Speed Calculator

[captain harlock]

The slipperential has a centerdiff, indeed, but it's not directly connected to the pinion. I want to make a direct connection between the pinion and the centerdiff to increase speed a bit.

New addition to the calculator. This might be hard to explain, but I'll try.

On several pages, there are images that change depending on the options listed. These images are made up of smaller images put together like a puzzle. As such, you can't simply post a direct link to any image since it would only be one piece of the puzzle.

So, each page that has images like this, there is a new button called "Get Picture". When clicked, a help window will pop up with a link that you can post in the forum so other can see it.

For example, on the "Lipo Wiring" page, the first section shows how a pack is built, but defaults to a 1s1p pack. If someone wanted to post a picture of what a 4s2p pack looks like, they just click the "Get Picture" button, and then copy the section in blue into a link on this page. Like this:

Link to see a 4s2p pack.

Hopefully this will be useful. :)

Added differential ratio for HPI Hellfire...

somehow I saw this coming.. :)

[BrianG]

Actually, I did it for you and Mike since you said you both got one. :)

Seriously, it's kind of an odd ratio. A 42T ring gear? But I actually counted the teeth and verified it. Figured it was oddball enough to add it.

BrianG, thanks for making the speed calculator. I use it all the time. Half the time I'm on rcmonster I have the calculator open as well, so when people say they X motor on X voltage with X gearing in X vehicle, I can quickly put that into the speed calculator to get an idea of what speeds where talking about.
I also use it to quickly check what kv all the different motors are, since I can't remember all of them. It's a lot quicker than looking for specs on a manufacturers website. If it's not too much of a pain would you please be able to add a few more of the neu 15 series motors, mainly the lower kv ones, since neu are the hardest for me to remember and theres the less of the neu's on there than most other brands.
If it takes too long don't worry, but if you do then, thanks.

[BrianG]

Cool! I'm glad you found it useful!

I guess I could add the other 15xx motors. :) I just have the ones I did simply because those are the ones Mike stocks.

EDIT: Added all the 1512 and 1515 data...

[Patrick]

Oh, he can special order the other ones as well though can't he?

[BrianG]

I'd imagine he can. He can get pretty much anything you want if it exists.

[Patrick]

You did it already! Thanks!

[BrianG]

Just fixed an error on the CRT.5 truggy differential ratio. Thanks to skellyo for the tip!

[jnev]

Actually quite a while ago, lol. :005:

[BrianG]

Yeah, it was about a month ago or so, lol. Thanks for the belated congrats though. :)

[jhautz]

I guess I'm kinda slow on the uptake sometimes! :p

Just an update to highlight changes posted from the temp forum into this one:

07/25/2007
- Fixed KV error for the Neu 1512/3d.

07/29/2007
- Added Oil Mixture Calculator.
- Added motor torque calculations to the Top Speed Estimator page.

Web links on the last page work once again since the original forums are back online. Yay!

And Seth556; I assume you are talking about the large array? Those aren't really error messages, but data for the help function (called up by the little ? symbols). Having them in an array makes it easy to call the message by array position rather than passing the text to the help function...
