Very nice. If I use my 1521 1y with 10S lipos, I'll be able to hit around 119MPH. I'll be happy if it goes 80 or 90MPH LOL. I'll run it first with my 2 11.1v 5000mAh KongPower packs to see how it does. On 22.2v it shows a possible speed of 60MPH give or take a few.

There are actually a lot more spur gear options than that. They range from a 67t spur to a 54t spur.

I'll keep on looking for the idler and main shaft pinion gear counts. I'll probably just end up emailing Associated...

Yeah, I kinda figured there were more spur options, but it's funny that they list the tooth count and pitch for some gears and not others. I suppose if you know the EXACT tranny ratio, I could work backwards to figure out the pinion. And speaking of that, I really don't need the idler gear tooth count since it doesn't do anything but reverse rotational direction.

If you're be building it, can't you just count the teeth while it's apart?

[jnev]

I didn't get a chance to rebuild the tranny today unfortunately. I was busy all day. I'll try to get it all done next weekend, as well as updated pics of the RC10GT that will be just about ready to bash.

Got an email back from Associated the next day... very fast response, and I emailed them on Sunday. This is what they said:

The top shaft gear #6571 is 20 tooth, and the idler gear #6570 is 26 tooth.

[BrianG]

Thanks for that info, but (and you're not gonna like this), the RC10 diff ratio was already listed in the calc as "RC10 T/B4", so I changed it to "RC10 T/B4/GT". I also added the tranny ratio for that truck, but it's actually 1 since all the gear reduction is done at the diff.

I found I had a duplicate "1.3v" value in the battery drop-down list, so I removed that.

I also added voltages from 2.2v to 2.6v to account for A123 cells.

New version uploaded already.

I'm a moron.

Thanks for the help Brian!!

[BrianG]

LOL, if you're a moron, than so am I since I didn't see it either. But, in defense, the entry was at the bottom of the list and needed to scroll down one line to see it.

Last night, my site had some issues where I couldn't access the calculator, and it got me thinking. Does anyone have any extra webspace to mirror these pages? It only needs 560kB of space and doesn't use any CGI functions (it's all client-side stuff), so it's just a drop-in...

I wish I knew a thing or two about this, but I have might plenty of webspace. I used FrontPage to make my site. I might have trouble figuring the password LOL. You will also need to guide me step by step.

This is what it says:

Disc Quota: 1% of 10000Mb
Bandwidth Quota: 1% of 250GB

Man I need to get some PC for dummies book. I have no idea to what the above things mean.

One thing I need

Is the new emaxx data added, so I can get gearing lol...... Just to add something to the to do list

=D

[BrianG]

Not yet. But, if you can get the gear tooth counts for the tranny, diffs, etc, I'll add them. If I have time in the next few nights, I'll see if the parts list and exploded views are avaiable for download and add them.

I will go see if I can get them
