lol, oops. :oops:

I'll fix that!

oops i lied, its right...

i ment first gear, it shouldnt be 18/70 should it?

BrianG 06.18.2008 05:23 PM

Well, I dunno. I probably put in whatever I was told. I don't verify each submission. However, the resulting total ratios look about right.

Lutach, I added the 65T spur.

OK, no more updates today! I think I did more today than ever in one day! The idea is to give me things to add before I FTP the files up! It's one thing if an update broke something, but these things are new additions. You guys are like marketing people that always have last-minute things to add! :wink:

You are the man. :yipi:

I was going to call you guys "end users", but I thought that was going WAYY too far! I don't need drive-by's at my house! :lol:

What happened to the Lehner motor specs in the calculator Brian?

BrianG 06.22.2008 12:47 AM

I took them out because Mike no longer has them and the list was getting kinda long for something fewer people have. Actually, they are still there, just commented out. I suppose I could add them back in but put them at the bottom of the select list...

jayjay283 06.22.2008 01:01 AM

Great program love it and use it alot, the Emaxx 3905 and new erevo come with 32p 68t stock spur and you have everyone but that one as far as I can tell, any chance of popping that in there next time you get a cravin to update ?

BrianG 06.23.2008 03:36 PM

Done. Also re-added the LMT motors, but they are at the bottom of the list now...

Arct1k 06.23.2008 03:42 PM

Brian re Buggy / Truggy / Truck comment it was in the brushless motor selector item.

You have a field for "Enter approximate vehicle weight (?): " I was thinkink that this could have drop downs based on typical weights for a Buggy / Truggy / Truck... I guess 8 / 10/ 12 lbs?

PS HP Pro in "Enter Front/Rear Differential Gear Ratio " is Hot Bodies LSP and could move into HPI...

Great series of updates! Buy yourself a pizza! ;)

Gotcha! But, I don't think I'm going to add that just yet. The weights of the vehicles varies a lot and I think it would be easier to just enter a number in that field.

Someone submitted "HP Pro" to me a while back and had no idea what it was. I don't follow the vehicle names as closely as most of you guys do. :smile: Anyway, I renamed it and moved it to a newly created "Hot Bodies" heading. BTW: Don't enter "hotbodies.com" while at work. It's "hotbodiesonline.com". I really should have known better. :oops:

Thanks! Can I buy myself Subway instead? I like that better...

Also fixed a bug in the wiring page when using FireFox that someone over at the Traxxas forums found.

hahaha, just like trying to go to Dicks sporting goods..

Silicone Oil Mixture Calculator
This calculator is based on the code from http://www.gesilicones.com/gesilwiza...ng/fluid2.html.
Viscosity of Fluid A 45
Viscosity of Fluid B 30
Target Mixture Viscosity 60

Mixing Percentages
Fluid A 171%
Fluid B -71%


I know non a valid scenario but you could have validation on input that Fluid A >= Target >= B or B >= Target >= A.

Temperature Calculation - Any thought of adding Kelvin?

Arct1k 06.27.2008 11:06 AM

Two Speed Gear Mesh Calculator - Might want to add a note that this is for Mod 1 gears

Thanks all

BrianG 06.27.2008 12:20 PM

Arct1k, are you trying to find work for me to do? :wink:

Fluid calc: Good idea. Didn't change it too much from the original aside from visuals. Might add that feature.

Temp Calc: I think C and F are good enough. Who (besides you apparently) uses Kelvin when measuring temps? :wink:

Two-speed mesh calc: Why does it matter what pitch it is? I know the code is technically using Mod1 to get the gear diameters, but the ratio is what matters. The only reason Mod1 is currently used is because I was going to add shaft-to-shaft distance, but decided not to, and didn't feel like changing the mesh code again.

brushlessboy16 06.29.2008 10:59 AM

Medusa motors run 60k max rpm not 40k.
:D

Arct1k 07.01.2008 10:07 AM

Fluid calc: NP

Temp Calc: Well Kelvin did... and it is rather cool ;) Not seen too many people measure distance in rods either

Two-speed: Hmm yes - its all relative...

:SIGH: I suppose I can add Kelvin. :sarcastic:

Added the extra oil mixture validation.

Added the CRT diff ratio.

The fix for the erroneous 40k rpm warning for the Medusa motor was a little different. The 60k rpm limit was entered correctly for that motor, but my warning system was using the old drop-down list method, so it was actually giving you the rpm limit of a whole different motor. Fixed now. :smile:

brushlessboy16 07.01.2008 01:17 PM

yay :party:

Arct1k 07.01.2008 01:30 PM

Disagree with the math - On the range condition that A or B equals the target - this is fine it should just be 100% / 0% mix...

I had included >= in the forumla

BrianG 07.02.2008 02:42 PM

Oh all right, I made the formula inclusive instead of exclusive. It would be pretty dumb to mix anything with say 50w oil to get 50w oil, but I suppose...

Also reworked the two-speed calc page to make it a little easier to use. Also added a couple things to the gear diameter calc.

kopfpilot 07.10.2008 06:46 PM

Is it possible to add the E-Savage to the presets?

BrianG 07.10.2008 06:54 PM

Sure, just give me the tooth counts of all the tranny gears and the diff...

kopfpilot 07.11.2008 02:45 AM

Thanks =)

The specs for the E-Savage:
Front/Rear Differential Gear Ratio: 38/13
Transmission Gear Ratio: 33/19
Spur Gear: 66T 32P (Stock)

Could you add the Ammo 36-56-2600 brushless motor aswell?
It has 2600KV, 55Amps current draw and a ressitance of 0.0084Ohm.

BrianG 07.11.2008 10:04 AM

I'll add those ratios, but I try to stick to motors that Mike sells, will sell, or used to sell.

Any other changes people want before I upload the updates?

brushlessboy16 07.11.2008 10:31 AM

umm isnt the rpm limit of L motors 50k?

Can you get it to make me a sandwich when I hit the calculate button? I'm kinda hungry. :lol:

BrianG 07.11.2008 10:47 AM

blboy: Yeah, maybe so, but people have found that the max "effective" rpm is 40k, so that's what I used.

skellyo: Will do...

EDIT: Actually, this will work for you. Why re-invent the wheel?

Virtual Sandwich

Sim Sandwich

Close, but the Pepperidge Farm site didn't give a pic after I built it. I think I'm going to have to head to Firehouse and pick up a sub for lunch.

BrianG 07.11.2008 11:05 AM

Probably a good idea.

I'll be going to Subway for lunch for my usual roast beef on wheat with Chipotle sauce, lettuce, tomato, onion, pickles, black olives, and S&P. :smile:

BrianG 07.11.2008 03:33 PM

E-Savage ratios added. Sorry skellyo, no sandwich function...

What's_nitro? 07.11.2008 03:36 PM

Skellyo, as soon as I finish constructing my SUB-atomic matter compiler I'll have it "make" you a sandwich! :lol: :whistle:

Do you want mustard?

Of course I want mustard....unless you can just put a little balsamic vinegar on it instead?

Arct1k 07.11.2008 04:44 PM

Thank you brian for the updates! Invaluable tool!

Sure thing! If Ron Popeil is still around when I finish it I'm gonna have him do the marketing. :wink:

kopfpilot 07.12.2008 03:59 PM

Thanks for updateing the E-Savage specs =)

BrianG 07.14.2008 10:49 AM

FYI: My webserver is currently down, so the calc is unavailable until it comes back up (forgot to pay the bill). Until then, you can download the ZIP file and use it on your computer.

jhautz 07.14.2008 11:02 AM

Love the "easter egg" 1:1 car tire size page. Never saw that before. :lol:



FYI I think there is an error on the LPR Crimefighter tire size in you R/C Tire data page. My LPR Crimefighters measure 5.8" not 5.25". I'm betting you got that from Tower who if I remeber correctly also has the wrong size at 5.25"
