Speed Calculator

[Aero]

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 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

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 as you can see i edited your picture to show E-flite connectors 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 ?

Welcome to the forums BTW!

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

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.

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 ).

lol, now I see! Yeah, that would be bad. I had to really look to see what you meant. 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!

[Aero]

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 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

besides you deserve it!
