Ok, that's it for a couple more months.

Why did you delete the "Drag-Adjusted Vehicle Speed" portion of the speed calc?

I only see "Theoretical Maximum Vehicle Speed".

Your the man :)

Fyi: Muggy diff gear ratio is 45/11 (not the same as a LST)

site, down. i get the page cannot be displayed message

[BrianG]

Yeah, I contacted my host and they said the whole server (I used a shared server setup) is down but the admins already knew about it. Must be really bad to be down this long.

Until the site is back up, you can download the site as a ZIP file, unzip it to a folder of your choice, and run "index.html". See attached zip file.

Brian, i downloaded your speed site files, and i still can't get the right diagram i'm looking for. can you provide me a diagram for 3 series lipo wiring? (in otherwards making (3) lipos into a 9S.

thanks

[BrianG]

Go to the "Lipo Pack Wiring" page, scroll down a bit to the middle section, and select "Use 3 series-connected battery packs" option.

Yeah, I gotta fix that. You must be using something other than Internet Explorer. I sometimes use the wrong slash ( \ instead of / or vice-versa) when coding and IE doesn't mind, but Firefox, Opera, etc doesn't like it. IE is just more forgiving...

I removed it because it's kinda useless. At high speed, ANY changes in body shape and other areas affects drag considerably. It sort of took an average drag estimate to compensate for the various setups, but it wasn't near accurate.

Will you be adding in the transmission ratio and such for a HPI Baja 5B/5T? There are people doing conversions now and it could become more popular and it'd be nice to include them in the speed calc.

[BrianG]

Sure, what are the gear tooth counts? I add whatever information people provide.

[Unsullied_Spy]

Baja 5T:
19T Top Gear
30T Idler
48T Diff

Baja 5B:
20T Top Gear
30T Idler
48T Diff

EDIT: Stock spur gear is 57T, I believe the pinion on the CB is 17T.

EDIT AGAIN: Stock Dirtbuster tire diameter: 6.6875", Baja Badlands: 6.88", Desert Buster Arrow (5T stock wheel): 7.5"

[BrianG]

Added Losi Muggy diff ratio. Also added diff/tranny ratios and spur gear for HPI Baja 5B/T.

Updates will be uploaded when the site comes back...

[Unsullied_Spy]

Thanks on both parts. I kept having to put in the Muggy ratio manually (I guess I should have dropped a message.)

[BrianG]

It's ok, someone posted the Muggy ratio several posts back...
