Sure. Like I said in that post; as long as he consents and provides the formulas, I'll be happy to add it.

I'll change the layout, user input error trapping, some code (mostly to use my own code library), and other small things to match the scheme of the rest of the site. But obviously B4maz will get full credit for the original idea. It all depends on him now.

There are exceptions, and 1:1 rollout isn't a hard and fast rule, but for the most part it works. It's meant to put you in the ballpark gearing ratio and then you fine tune from there based on what your electronics can handle, how you plan on driving, etc. There are so many factors to account for, 1:1 rollout is just to find a good starting point.

Suggestions
 

this rc calculator is SO cool, and am glad to se it improved and updated! I would like to help, or contribute, comment and suggest..I would like if you put in some 'FYI' fields, maybe not to be used in calculator, but to jsut write the info, if you know what i mean..would also be handy if one capture the screeen, and have some custom lines, that tell the model/setup comments.

"pole count" of motors would be nice to have data on..(missing pole count in motors below..dunno the count..)

a few things i'd love to see in your calculator:

could you add a drop down menu under motor resistance ? and also add some motors (see below). i know you say that 'mike dont have..' but i think its handicapping/encribbling your amazing calculator sticking with what mike has.
---
More/better help/tip on 'current motor draw in amp'
---
more clarification on '1:1 rollout'. why care for this, what to obtain, go for, etc..
---
In 'Parameter solver' and other places, could you include KPH, or in general to some extend, metric values ? maybe inside the usual ()-clamps

and can you add these tranny gearings:

E-savage metal tranny low-geared: (32/20 x 24/26) = 1,476...

(presently im using additional gearing 0,85 to make above 'happen')

E-savage metal tranny low-geared: (32/20 x 26/24) = 1,733.. (thats same as stock)

E-savage spur gears: 60t, 68t, 70t, 72t(all 32p), 49t(mod1)

On system wiring page:

Can you add Mamba max and Mamba monster esc's ?
Can you add 3 fans option ?
---
"Brushless parameter comparison": that seems neat and logic, but what is this used for, could this one be expanded in a way ?
---
On "Lipo wiring" page, could you include 'align/electrifly/JST XH connectors ? that would make the pics look more correct. i fooled around with the pic and made something liek this. http://i204.photobucket.com/albums/b...lipo-right.jpg http://i204.photobucket.com/albums/b...lipo-wrong.jpg

hope its ok i edited the pic ;) . Now im at it, it would be nice/neat to select bullet connectors, if thats worth a thought..:whistle:

BTW, I believe its important/good rule, to connect main leads FIRST, and disconnect main leads LAST.. can someone nod to that ?

Finally, I have wish: If you could make at least 3-5 setup saving (/memory slots) buttons, like the 'Dark Horse RC calculator has' , see http://dhrc.rchomepage.com/RolloutCalc.htm . then one can keep a previous setup, enter new setups, and compare them easy, instead of having multiple windows with the calculator. Perhaps take the best from dark horse calculator. I see is has battery capacity, truck/car weight, wheel RPM..

Also, selecting lipo cell voltage, so which to pick, 4.2V not that accurate in practical terms ? How about some sorta 'recommendation on what to pick here (may have to do with the esc/motor ratings?)
---
On the gearing pages: Would be nice and handy to have fx a converter/recommender, that switch a 32pitch spur/pinion pair, to the closest approx mod1 gears, well only thinking out loud. Maybe its already there.. or a pop up window that sugest the gear teeth to be used to accomplish same ratio/distance between gears..well u figure..
---
keep it up BrianG, This is an ultimate and very useful calculator! You work is VERY appreciated!! :yipi: I hope you can use the suggestions <dont let me down lol>

Edit: ...this is my first post on this awesome forum. (But lets pretend its post#763..sounds better)

HELLO ALL.. :party:

Criminy! That's one heck of a "to-do" list! :oh:

I'll try to answer all the points:

- Note fields would be handy for screencaptures I guess, but might confuse the user. Most would be asking "If that has to calculation purpose, why is it there?". Usually, people post the setup in a forum post and then add more details in the post.

- Motor pole count. Actually, I do have that information already in there. :wink: But since it's not used for any calculations, it's just visible on the "Data Tables" page just for informational purposes.

- Yeah, I can add more motors, but as you can see, the list is quite lengthy already. I try to stick to the more common motors out there and/or the ones that Mike sells. If others chime in saying those would be good additions, I'll add them.

- Motor current draw: What type of additional help is needed? There are SOOOO many variables that influence this that the only two usably values IMO are 0A and whatever you think the max would be. Everything else is pure speculation.

- The 1:1 rollout was something recently added by request. I'm not really sure what benefits it has other than as a starting point for gearing. So, that's what I put.

- Adding metric units should be fairly easy to do. I'll check into that.

- Adding tires, tranny, spurs, and chargers should also be easy to do. Check for them in the next update. :smile:

- System wiring page. Adding specific ESCs is kinda redundant. I would prefer maybe "classes" of ESCs; something like Opto-ESCs, ESCs with linear BECs, ESCs with switching BECs, etc. Something for me to think about.

- BL Parameter Comparison page. This was just a little project of mine trying to find an easy way to graphically show the relative impact of gearing, voltage, and motor kv. I specifically wanted to keep it simple for the newbies. Once they understand that higher kv is not always the best, then they can go into the other pages for detailed calculations.

- Lipo wiring page. I tried to include the 3 major lipo hookups; Trakpower for its unusual wiring arrangement, Hyperion for its odd wire sequence skipping, and everything else. "Everything else" has the wires in sequential order with no skipped spaces, so that covers pretty much anything out there. And, actually, you CAN wire it up like in your "wrong" picture, but you have to be SURE you have the plugs in the right order. My personal Y adaptor does have that common wire still hooked up, but I know what I'm doing. :smile:

And the type of connector is pretty much irrelevant IMO. I just chose Deans because that's what I have and it looked ok. :smile: Besides, people have different ways to use bullets (ie: two females on the pack, vs one male and one famale for "polarization").

- Electrically speaking, it makes no difference which order the wires are attached. The only time it matters is if your specific charger/balancer specifically says to connect things in a certain order.

- Memory slots. Yeah, that can be done, but really complicates things. Since I'm using a static site (no active server content), I'd have to rely on cookies. And I hate dealing with cookies. They don't work well when I'm developing on my computer, so I'd have to upload test code at my site each time to see if it works. I would really rather not go that route. But TBH, there was times where I wish I could have saved a setup because I had to go to another page briefly, but didn't think it was worth the bother to implement.

-Lipo voltage. Yeah, 4.2v/cell is not a practical voltage value in a setup, but I do have the 3.7v value highlighted to implicity tell the user to use that one.

- Gearing pages. Since there are a ton of different things a user could be looking for, I just provide the basic tools and let them figure whatever they want to figure out. For example, if they want to switch between Mod1 and 32P but keep the same shaft-to-shaft distance, they would use one page to get their current shaft to shaft distance, and then another page to figure out the gear diameters to match that for a different pitch.

Whew! I hope you don't think I'm trying to get out of doing more work. I don't mind adding features as long as 1) it would be useful for others, 2) doesn't complicate things uneccessarily, and 3) I feel like it. :smile:

Welcome to the forums BTW!

uhh... Brian... you probably gonna hate me after this, but anyways...

http://www.outcastrc.com/features/scales/scales.htm

Exactly! You've got more work to do! :diablo: The height is actually the diameter of the tyres. Good luck :lol:

lol, I'm all over it. (not). :tongue:

Thanks! It's not really a to-do list, thought this cool calculator author need feedback as thanks, do not think that i know all im talking about :) It's nuthing but ideas and such. So you judge whats worth a second thought. No hurry, promises and all that..some of the suggestions are old, but finally vented them. then if other like them, i hope they would mention it or something, to reflect its not only ONE person who like to see some particular 'udate' (or a dozen, sorry they came in a bunch..).

Note field: confuse users..ok then. I suppose by not filling the field out its not confusing ? Too bad, I liked that idea :smile: In fact all captured calculator images look alike, but i guess one can always photo edit it, or title them..

Motor pole count: too long list? i respect your implementation-wise arguments, i cant speak much for that. whatever works now is nice, and a longer list dont sound like a bad thing..dunno maybe its good to have the pole count on motors in the drop down curtain..maybe not? all these things in general with stating/posting data would especially help if LOOKING for some data, or be sure what to pick. it may maybe be too idiot-proof.. If all the motor data, like pole count is in the data table, cant the drop down curtain somehow be linked to that, if that make sense?

and YES ammo motors are popular, i have 3 of them. They are very common to me. In that case, Mike should sell them :intello:

Motor current draw: some guidance would be nice, like a drop down curtain with some numbers. I doubt newbies understand this calculator much, but i recall myself! say, I got some number from part specs and dunno where to put it. I punch in 12000Amp. fx. in the ?-sign or in drop down curtain some where-about numbers could be picked or referred/related to. You could also excess the use of likely words. Fx. 'average' and 'burst' and 'max', so to the user wont be in doubt where to put some number. liek a motor come with 2-3 specs. or say, some lehner motor, like a 1940/7. is that 1940kv..7 pole..no. Bad example. cant explain it better tho..my bad english..

1:1 rollout: isnt that rollout thing the result of acceleration+torque relationship ? why is it goo to know that the truck move one inch for a single motor rpm. i dont believe in that 1:1 'rule', its some small scale torqueless buggy thing no? and I suppose rollout ideal, would have something to do with KV and length of a motor(a motor model)..and weight if vehicle etc..? but me dunno - maybe ill get it later..

BL Parameter Comparison page: it does look interesting. Perhaps some check-mark boxes, with influental components could be cool to have and see what happens/changes..but i suppose ur in developing something already ;)

Lipo wiring page and connecting sequence: Can you please re-check the 'wrong' picture in detail Brian ? hehe, i also know what im doing (well once in a while!) and once i had an incident.

Deans/bullets: just cosmetic rambling :oops: as you can see i edited your picture to show E-flite connectors :lol: i know its irrelevant..

Memory slots: oh ok. what about making a 'get picture' buttom for this and that/here and there, so the picture could pop up in a new window, or one could save it as a file. or about file, ability to save the seup and load it (like import-export)

Gearing page: maybe it could be nice to have a 3rd sub-calc there, like type(select) in gearing/~ratio, and either spur or pinion, select pitch, and get result, change pitch and have one gear value fixed, get result ?

Yes, its only humble requests..and not all too clever. i did read that you have asked feedback often ;) yes i read all 51 pages first :sleep:

uhh.. wow. :surprised:

You do to much Brian:yes: but thats why we love your calculator:tongue:

I would have done like you said and stopped what's available in RCM.

First of all, what is "fx"? Is that like "ie", "eg", or "example"? I guess I could maybe offer some very basic guidelines as to what current numbers to use. 12,000A is not very realistic unless you have a 500Ah 24C battery. :smile:

Like I said, it was something that someone requested. It's a good starting point for a very safe gearing for someone with no experience with how BL setups act. From various test calculations on different setups, it tends to be very conservative for gearing. Of course, top speed would suffer, but the chances of pushing the components too hard are pretty slim if you follow that rule.

Like I said, it was just to give newbies a basic idea of how things work. Since it doesn't have absolute numbers, it just shows relative changes. Definitely not definitive (lol, that was a conflicting statement :smile:).

lol, now I see! Yeah, that would be bad. I had to really look to see what you meant. :oops: I think for the sake of simplicity, I would add some kind of note or indicator showing which balance plug goes with which main harness wire.

To be honest, I just don't feel like creating graphics for every combination. I can just imagine if I add E-Flite connectors, someone will say "where are the traxxas plugs", or "where are the bullet plugs". I think people are smart enough to realize they can use whatever connector that floats their boat.

The import feature would be the easiest way to implement this I think. The current export feature is "blind"; meaning, it simply looks through the page and gets the field title and value for any field with a custom element attribute. I'd have to design the import/export system such that it is backward compatible with any future upgrades (like if I add a new field, or remove one). I'll have to give it a little thought.

This was actually requested a while back. But due to complexity, I compromised by creating a table with alternate pinions which show the resulting speeds (click the little gears icon in the results section - in the top speed estimator only).

You have WAYYYY too much time on your hands! :whistle:

concludes broadcast day
 

yes, fx. = for example

If i had too much time on my hands, i wouldnt have bothered you in first place. I actually meant to email you instead, but anyways you can delete the post/data when you dont need it anymore.

I took, that it was making common sense to have read the whole thing, before making suggestions, then read that you often welcomed thoughts and opinions..didn't really know you were still developing the calculator, before once I saw some minor changes (thanks to kopfpilot) here and there.. It's by far the ruling <free> rc calculator I know of yet. Well it was interesting to read the history of it. Not much to read, but it not my native language..

pinkpanda> Very helpful..Doesn't matter. We both had a say.

good luck with the calculator. I owe you a high class pizza, but if your BMI prefer I might paypal you instead, so much easier over long distance :wink:

besides you deserve it!

In case no one has noticed, I made several changes the last few days. The following list is taken from the release notes file:

- Added form import feature. This allows the user to save prior setups into a file and reload them at a later date.

- Changed the method used to export field values for forum posting to prepare for a possible new feature.

- Added more detailed "help" explanation for motor current value in the top speed estimator page. Also, added a warning when the motor current value exceeds 250A.

- Added more details for lipo Y adaptors to help reduce the chance of mis-wiring.

- Added e-Savage metal tranny ratios, and spur gears.

- Added HPI Baja, HPI Dirt Bonz, Trx Response, and Trx SportTraxx tires.

- Added Great Planes Ammo 36-56-2600, 36-56-1800, 36-56-1200, 36-88-1280 motors.

- Added Imax B5, Imax B6, Imax B6AC, Imax B8, E-Station BC8DP chargers.

I probably need to explain the new import feature a little more. There is a new button on the "top speed estimator" and "parameter solver" pages that says "Import Values". This lets you import values from previously exported data. You would save the exported data to a file (or post into a thread), and then at a later time/date, copy the text to your clipboard, and then re-import the data using this button. The form fields will be repopulated with the data so you don't have to manually type in all the data again.

Thanx Brian! Really love the import/export feature!!

Didn't know Great Planes had a 88mm!

Brian, how does the speedcalc calculate torque?
If I enter a higher amp draw the torque outcome increases. But isn't it so that a higher torque motor will draw less amps? (comparing two motors of the same series: a higher kv vs a lower kv, both geared for the same speed@the same voltage)

Torque=(1352/kv)*amps

So, lower kv and/or higher current equals higher torque. And then, the lower the gearing, the higher the torque as well.

Thanks. What I'm trying to understand is this:

You can get two motors from the same series (neu 1515) and run them both on 6s. The lower kv motor would need higher gearing and the higher kv motor will need lower gearing to achieve the same speed. Why will one motor run cooler and longer than the other?

My assumption was that both motors would produce the same amount of watts and therefore the same amount of amps. But if the runtime on both motors is different, one will actually pull more amps&watts...

awesome!
 

Cheers BrianG! :intello:

Where can I find the Keda Model 1900kv motor ? When picking motor, I thought it would put in the resistance as well but it doesnt. also about that 'enter current draw' should i put in 3.9A or 55A? under the ?-sign is says 'motor current draw'. even my medusa motor wouldnt draw 200a ? it continue about weight of truck.. i dont understand this.

i was hoping it put in the right specs of motors in the right field(s).

Section two, in 'gear diameter calculator' would be nice to have 2 or 3 of that next to eachother(sidebyside) so one can compare different gear sets.

brilliant work again!

Aha! I found the secret page on the Speed Calculator website! Yeah! :yipi:

Found it by accident.. My mouse hit the keyboard and clicked when I moved it over to the left and I found the weird page. The tire size page...

Cool stuff BG

Could you add shock/diff oil conversions to it? I have no idea what CST is and it seems that's what everything is measured in now.

I'm not sure either. And I don't know what CST is either. Give me some data and I'll see what I can do. But, from previous conversations, diff oil viscosities can vary from manufacturer to manufacturer for the same labeled weight, so not sure how much value it will have...

Added another page, but not sure if it has any value. Try it out, and if it is too confusing, I'll remove it.

That's handy for me:smile:

I don't have anything that will measure batttery resistance but I can work it out with this calculator.

Wow, its gettin better and better BrianG

But how does LESS gearing (on BL parameter comparison) result in LESS heat components (thinking of the motor) ?

I have a few suggestions to add. (up to you man :wink: )

HPI E-firestorm:
spur 48p: 87t,
tranny:
top drive gear 48p: 20t
idler gear 48p: 28t
diff gear 48p: 52t (diff ratio 1/1)

transmission gear ratio:
(28t/20t) x (52t/28t)
1,4 x 1,86 = 2,6

HPI Savage Flux bulletproof diffs:
29t/9t = 3.222..

If anyone know the details on above motors, its great.

Losi XXL gearing:

the output gears in the xxl tranmisssion have a 29/16 ratio
2nd gear xxl foc: 22/23*29/16 = 1,894886364
2nd gear xxl foc & swap mod: 23/22*29/16 = 1,733695652

so swapping to xxl output gears in the lst2/afershock tranny(1,89) gives almost the same reduction as the gear swap mod in the lst2 tranny(1,91)

Update:

- Added the Amp draw vs speed calculator originally in spreadsheet form created by b4maz (Nick Maslowski).

- Added Traxxas VXL and HobbyWing motors.

- Added E-Firestorm gears and Savage bulletproof diff gears.

Thanks for all your hard work Brian. I didn't realize the new HPI diffs had different ratios. Looks like it's time for another paypal donation, even if it does go for diapers.

Incase some of the new members don't know or the old veterans forgot. You can donate a couple $ to our BrianG for all his hard work and time he puts into the web page. He does it on his own time and dime for us. I'd be broke if I gave him one dollar for everytime I used it but I am grateful for the site and all his time spent on it. So I try to keep him happy now and then and add to the kitty. Just click on the PAYPAL donate link on the bottom of any of the pages to show your appreciation.

Thanks again Brian.

how do i calculate the losi 8ight-t 1.0?

Use the

8th scale truggy (typical) 43/10

Thanks for the poke, Gee. I feel guilty for not knowing that was all voluntary work. :oops::whip::whip:
Donation made.

lol, I don't want anyone to feel obligated to donate. But if you have a few extra coins burning a hole in your pocket, well.... :whistle:

BTW: I just checked my email and noticed some VERY gnenerous donations! Thank you VERY much! It is appreciated!

Hi BrianG,

I'm interested in the same type of thing and put a lot of work and some money into making my site - http://rcgearing.com Could you take a look and see if it's good enough to go into your links page? My site has a google rating of 3/10 and it has no ads and is completely free and always will be free. I don't even ask for donations.

Thanks,

Jeff

Sure, I'll do so on the next update.

Thanks! You are the best :)

Brian,

Can you make this thing an iPhone app?:wink:

I'd love that. :yes:

i wonder if it was any use. I see Brian did not like to ad 'things that rc-monster dont carry' . (do i look like i dont care as much as brianG..) I have other things to add to make the calculator more flexible and functional, regardless of the rc-monster forum..

this could be the world's best rc calculator. i only say it cos it could be so. Whatever connections there are..that sux. and for once the better half agreed.

BrianG: could you put in all spur gears for savage ? would be nice for text and numbers for tigure when capturing screen shots and such.

keep up the good work dude. if you had time i'd email you some good thrills..

anyway nice work, priceless and so much worth of use, just great!!

It is an iphone app ;)

You can download this thing called air sharing which makes your iphone/itouch be able to act as a file repository - just unzip and upload brian's download and you have it on your iphone/itouch...

Had this for 18months :)

Thanks! And the decision to limit the products to what Mike carries is in 4 parts:

1: This whole RC Calc project started as a single simple page primarily for the members here. So, limiting the product line to what Mike carries made sense. Plus, since it really started here, it is out of respect to keep the main products to what RCM carries. I honestly had no idea that it would be as popular as it is. Every once in a while, I see referrer data on my server logs that points to RC sites and in languages I have never even heard of.

2: Updating simplicity. Let's face it, there are TONS of R/C products out there and it takes time to keep it updated.

3: Ease of use. If I put in every RC product out there, the drop-down box "shortcuts" would be extremely long and totally negate the purpose of having them there in the first place.

4: This entire site is client-script driven, which means all the data for all the motors and vehicles is stored in javascript arrays. Adding everything out there would make the resulting data file relatively large and might even make the script run sluggishly.

As a side note on point 4 above: I had thought about changing the data arrays into a database driven system. This would make updating much faster (I could write a little GUI for doing this), and I could use AJAX to retrieve only the data needed, but this would no longer be able to be run offline from your pc. I also thought about using XML files instead, but cannot seem to find a suitable cross-browser method to load XML on the fly that works both in offline (when stored on your system) and online (run directly from the internet) modes.

As far as iphone app is concerned, I hesitate to offer any guidance. I don't know how robust the iphone javascript interpreter is, how closely it follows the W3C rules, or if future iphone versions will have any compatibility issues. Arct1k said it can be downloaded and run on the iphone, which is cool, but who knows if it will still run in the future.

And, if there are things missing (ratios, etc) post the exact tooth counts of all gears and the resulting ratio so I can figure out how to enter the data correctly. If I missed something already posted, I offer my apologies, and simply repost the data as a reminder.

I think he was referring to a previous post...

Yes, BrianG's calc is an awesome tool and he has explained why it has limitations. Why can't you accept that ? I hardly think it is worth name calling for someone to have loyalty. BrianG is well respected on this forum ( and I'm sure other's) and your posts seem to centre around BrianG and his calc so your ranting will fall on deaf ears around here. :whistle:
