Temperature Calculation - Any thought of adding Kelvin?

[Arct1k]

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

Thanks all

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

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?

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.

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

[Arct1k]

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.

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.

yay

[Arct1k]

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]

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.

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

[BrianG]

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

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]

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?

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

[brushlessboy16]

umm isnt the rpm limit of L motors 50k?
