By the way, I just looked and there is apparently already generic values for diffs. Look in the "miscellaneous" company.

N/m then I withdraw my objections!

Update:

Changed the motor XML format a little. Smaller filesize and more logical arrangement.

Added a charger calculator page that helps figure out the minimum chargers specs needed to charge a specific battery.

so, will the rc8t be making it into the "associated" brand or am i missing something.

Like most truggies and buggies, you can use the misc. entry and use the generic 43/13 (buggy) and 43/10 (truggy), and 1/1 transmission entries.

Unless someone posts or I otherwise am sure of the values, they don't get entered.

Associated RC8T is 43/10 with a center diff (1/1 tranny).
Associated RC8B is 43/13 with a center diff (1/1 tranny).
SC8 is 43/10 with a with a center diff (1/1 tranny).

Associated SC10 is a 2.6 gearbox same as the RC10T/etc.

Losi XXX-T is 2.43.

Thanks for that info!

I use gear tooth counts, not ratios (decreases rounding errors when calculating), so what gear tooth counts make up the XXX-T? I assume since the SC10 has the same ratio as the RC10T that the gears are the same...

No idea; double checked the Losi documentation and they don't list the gear tooth counts for the three internal gears. Next time I pull it apart I'll have to remember to count them.

I added the Associated RC8T, RC8B, SC8, and SC10 trans and diff data. Let me know when/if you get the XXX-T data...

Ok, sent an email to Losi, see if I get a response (hahaha).

the rc8b ratio is incorrect. it should read the same as the truggy.

here's the info from team associated:

http://teamassociated.com/cars_and_t.../Factory_Team/

The page you linked is for the RC8Be electric version. I think he is referring to the nitro version of the RC8B. I don't know if it makes any difference...

It's the same through out all of the 1/8 vehicles. i've got both of them.
here's the info from the nitro version as well:

•4.30:1 ratio gearboxes for maximum punch

RC8B Factory Team (nitro version)

Update:

Now that much of the data is in XML form, I have created several pages to manage the data via the web interface. However, I need a few testers to make sure things work right. I did my own testing, but it's always better to have more than one set of eyes.

Ideally, I plan to have a few people (mods, long-time reputable members) with the ability to edit/add data as needed, but first need to make sure everything works.

I only need a few people as of right now, so if you don't mind helping, send me a PM and I'll provide the link and login credentials.

when i ran a xxx-t back in the day the tranny was a 2.56:1 don't know if that helps.

Update:

I reworked the R/C Calc site so it will fit nicely in a smaller area primarily so it can be used as a Facebook application. I know some of you won't like the new layout, but the developer gets to decide what's best :tongue:. Besides, what do you expect for free? :wink:

However, I can't submit it to the applications directory until it gets "5 total users or 10 active monthly users". Don't ask why because I don't know. Makes no sense to me since I would think you'd need to submit it to get a user base. Apparently, they do this to discourage the use of applications that require user authentication. But since my app doesn't require it, you'd think it would just publish?

Anyway, if any of you are a registered facebook user, could you do me a favor and go to the application page and "like" it? Not sure if it will help though, but it can't hurt. If that doesn't do it, I'll have to trawl through all of their API documentation, 99.9% of which does not apply, but whatever.

Here's the link since it won't even turn up in a search: http://www.facebook.com/apps/applica...14159475311275

Liked.

The new layout is actually pretty good- no more difficult to navigate, though the right to left switch when using each separate tool is a little odd at first.

You know, the only thing missing is some nice big logo or image on the home page of the r/c calc page/site- big white expanse with a link at the top looks rather empty- needs some epic picture or logo etc..

Wait!!!! :oh::oh: So I gotta get a facebook account to use your calc now?? Don't like that idea. Ive got no use for facebook, but I use your calc page all the time. Could be the mose usefull piece of software ever written.:intello:

I thought about putting a logo somewhere to make it look better, but A) I don't have a logo, and B) I don't like to add stuff that doesn't directly improve usability. Glad you like it though. I thought it was a bit "plain".

lol, no no, it's still available in the same old location. As a matter of fact, the version on facebook is simply an iframe that contains the site. I just wanted to add more exposure.

OK guys, I have 6 "likes" and 8 "monthly users". I need 10 monthly users in order to submit it to the application directory. So, please take a minute to visit and "like" it. Please? :smile:

The link again: http://www.facebook.com/apps/applica...14159475311275

I liked it

Thanks guys. I got the required 10 users and was able to submit it. Now to see whether FB accepts it. If not, no biggie since it's on my site anyway. This was just a way to get more exposure.

Thanks to those who "liked" the app. I was able to submit it last week. It took a few days for FB to approve it, then several more days for it to appear in the application directory.

The FB version is exactly the same as the normal one (actually the same place except FB contains a window with the site in it).

http://apps.facebook.com/rc_calculations/

In the future, I will be looking into making the page look prettier, but it'll work for now...

So how to do I save it or add it to my app list?

Hmm, I dunno. :smile:

It doesn't require authentication (meaning it doesn't read your profile info), so I'm not sure how to do that. I'll have to read up a bit more on the FB API. But whatever I add, I have to be careful not to cause issues when the r/c calc site is viewed directly from my server.

Edit: I'm not too sure on this because the application was made under my own account, but on this page is there an "Add to my page" button on the left? Maybe this will work? Let me know.

Update:

Just made the entire Calc site XHTML 1.0 compliant. I know that doesn't mean much to most of you, but if you see something that doesn't look right, let me know.

All,

I'm trying something out and need some feedback. I'd like to get rid of the drop-down lists altogether and came up with a "suggestion box" scheme. I made a test version of the "rollout ratio" page for you to try out: http://scriptasylum.com/rc_speed/tes...out_ratio.html

Instead of selecting from drop-down lists, you just start typing a brand, model, or value and a box shows up (after 3 characters or more are typed) with the first 15 suggestions. I can't decide if this is faster/better, but thought I'd get your opinion.

Meh. Its ok, not sure whether I like it better or not.

Think it might be better to allow saving of the settings (just in a cookie; it can store up to 4kb), not the values, that then they can be chosen from via a dropdown. That way we can enter some of our favorite vehicles in, be able to quickly load them up and play with them.

I thought about doing something with cookies, but discarded it and decided to implement the export/import function instead. I intended it so users would configure their setup, export the values, save them to a text file on their computer, and then re-import them at a later time.

But TBH, I've never really liked using cookies. They have their uses I suppose, but I'd rather not use them, or use session variables when I can.

The export feature is nice for exporting and posting in a forum or such. Would be nice though for a xml or json based import/export that is able to set the selected items, not just the values.

I just suggested cookies as its a straight forward client-side data mechanism that without any additional packages is available from javascript. A way to store data and make it available from within the site. You could use google gears too, but that requires a client-side installation.

There isn't anything really wrong with using cookies. Cookies are nothing but a text-based data storage mechanism on the client-side. As long as their isn't any real personalized information in them, there isn't any harm in it.

Session variables, no idea why one would not use them as appropriate, for storing data that is present between page transitions (although there are some other mechanism for that too) but more importantly information that can be cached for the user while his session is active (normal defaults are 30 minutes under most APIs). They aren't really appropriate if you are doing a site, such as yours, that can be downloaded and run locally via just html files.

I personally like the drop down menu's. I use some of your calculators when playing with my drag cars setups and do not necessarily use std components. I also may use something from a menu to try and see what results I get. This can help me decide to use a particular manufacturers components.

Can you have both?

What do you mean by "...import/export that is able to set the selected items, not just the values"? Both json and XML are pretty easy to do, but the way it is now does two things: 1) allows pasting results directly into a forum and 2) doubles as a data storage method should the user desire. Maybe I just don't understand what you are saying?

As far as cookies go, I've just found them more trouble than they're worth. People may disable them, or the browser may prompt the user which may alarm some who have no clue if they are harmful or not (they do have an undeservedly bad reputation). It's been a long time since I've used them, but I remember issues with cookies when running locally (when the user downloads the package and runs it on their box). So, unless there is a real business reason, I try to avoid them.

I think you misunderstood me about session variables; I DO like to use them, but only use them for apps that need server security where I need to remember the user. But yes, this app is designed to run both online and offline, so it's really a moot point.

Yes, I could technically have both. However, I was trying to find another method of pre-set selection that didn't use drop-downs at all. Two reasons for this:

1) The additional width required for them tends to screw up the facebook version of the app (adds horizontal scrollbars, which I HATE).

2) I hate to admit this, but the current use of the drop-downs is not "proper" at all. The right way to populate them dynamically is to use the DOM to do so. However, that takes too much code and I'm too lazy to re-write it. So, I use javascript to write/re-write out the HTML on the fly. Certainly not elegant, and someday, browsers may frown upon this because those form elements do not technically exist, but it works right now. This has been something niggling at me for some time, but since it works, I haven't worried too much about it.

This "ajax-like" method is the only other simple way to allow preset selection without a whole lotta work.

Some of that is over my head, but I get the picture. In the end this is a great service you offer and I would be happy for you to do it the easy way that works for you.

Thanks
Brow

Never mind about checking out the new suggest box feature. I decided to scrap it...

hey BrianG. Im not sure, but it looks like this thread is turning into a programming thread. anyways. is it still ok to submit motors, some esc and charger specs ?

as for progressiverc, thats not my table, i cant help really, i only 'served an idea/wish' if you know what i mean. i cant possibly match any data from you two either, i only have xp from decades ago.. I am forever glad that this rc calculator is still progres. its the best thing in rc ever.

quick question: is there any way to minic load on a brushless system set-up, as to like set torque factor/nm of outdrive etc? using a watt meter didnt seem useful when out of a truck..?

can we vote for a new background skin for the calculator ?new theme and out goes that carbon fiber. but of coz thats just merely fine tuning of the calculator..haha :mdr:

lol, yeah, it does delve a little on the programming, but there are some here who have good ideas so I like to keep such discussions open. Yes, additions of motor/diff/tire/transmission/spur gear data are always welcome. You can either post that info here, or send it to the email address listed in the FAQ page of my site.

I sent you a PM, but in short, I spoke to Dave from progressiverc and he wants to do something, just not sure what yet.

Mimicing a load on a setup can be good if the user knows what they are doing, or the results could be completely off base if they enter in garbage. As in any programming: garbage in=garbage out. It's not like aircraft where the prop places a fairly constant load on the system; with cars, it's MUCH more peaky. But, a couple pages do make an attempt at implicitly taking load into consideration:

• http://scriptasylum.com/rc_speed/_speed_amp.html - Takes drag and vehicle parameters into consideration to estimate power needs.
• http://scriptasylum.com/rc_speed/_car_setup.html - Allows you to enter motor resistance and arbitrary current draw to estimate adjusted kv, torque, and power.
• http://scriptasylum.com/rc_speed/_power.html - Gives an inkling of power needs by estimating amp draw given runtime and battery capacity.

I suppose you could suggest a new background skin. Not sure if it will be implemented, but I will consider it. I try to keep image use to a minimum to speed it up, plus it's more utilitarian, so design takes the back burner.

Seriously now - No Summit transmission ratios? ;)

@Snoop: Fixed. Thanks!

@Chris: Provide me with the internal gear tooth counts (and the final ratio just so I can check to make sure the gears are in the right order) and I'll gladly add them. This pic should give you an idea what I need:
