Speed Calculator

Thanks!

Don't know if I saying it correctly.

For example you would put all the info in for your RC on the est speed calc. Then instead of needing to go back and changing the pinion size from 10, 11, 12, etc. to see the different speed you would get. You could hit a button and it could display a table or something with the different speed you'd get for say a 10T - 20T pinion. It be cool then to go back and change the spur gear and see what the table would put out using the same pinions. Even on the reverse side say it would pump out the size pinion for estimated speeds of 30, 35, 45, 50, etc.

What do you think?

For some reason, I was downstairs thinking about how I was gonna make LST2 shocks fit my XT8 and the solution to this request hit me. I wasn't even thinking of anything close to this, but all of a sudden I remembered this request and an easy way to implement it. Weird.

Anyway, I added "speed vs pinion" feature to the top speed estimator page. After calculating the top speed, a gear icon will appear next to the estimated speed field. Clicking that will open a help window showing the speeds for different pinions.

Hey Brian,
Any chance you could update the Flux tranny ratios in the calc? Here is JThiessen's scan of the manual w/ the new gears

Great idea on the on the spd vs pinion. Its really nice to just look at the ranges instead of having to re-select the pinion. One thing tho, perhaps could the list read down the column instead of L->R? Just makes it a bit tougher to read. No biggie.

Also, couple other little things. The Sav XL spur, 52T iirc, Flux is 44. Lastly, regarding the Cen diffs. The genesis/nemesis and matrix all use the same diff. People may or may not know that. Don't need to update the name, but eh, some of the others are multiply named.
good job as always!

This has helped me so much. Thanks Brian.

Update:

- Fixed a small display bug in the Data Tables page
- Fixed motor length value for Medusa 60mm motors (was listed as 50mm long).
- Added the few new 50 and 60mm Medusa Motors, as well as all the 70 and 80mm motors.

Did you get a chance to add the ax10?

[BrianG]

Oops, no.

I saved the PM as a reminder to go out and get the gear tooth counts, but forgot. I'll add it to my to-do list.

Brian, this speed calculator is freaking sweeeeet, thank you!!

[MetalMan]

If you want, you can also add the HPI MT2 and HPI Wheely King diff ratios, which are the same as the AX10 (38/13). The Wheely King does have a transmission, but I have no idea what the ratio is.

[BrianG]

I'm downloading the 35MB kit diagram for the AX-10 as I write this. I'll add those ratios as well...

portyansky: Thanks!

[BrianG]

More updates:

- Fixed display bug for transmission data in Data Tables page.
- Added Axial AX-10 Crawler differential and transmission ratios, and spur gear sizes.
- Added differential ratios for HPI MT2 and HPI Wheely King.

Thank you....

[MetalMan]

Great! One of these days I ought to click that Paypal link.

[JThiessen]

Question - I noticed that if one does not use the preselected spurs, the calculators have no way of recognizing which pitch you are using, therefore, the calculations must assume a basic pitch. Is it mod1?

Thanks.

[BrianG]

Actually, the pitch is not needed at all in the calculations, they are just there for informational purposes. The calculations simply use the tooth count...

[BrianG]

Before I get any PM's: Yeah, I know the site is down. 1and1.com is apparently having some issues (even their main site isn't working). If you "need" the calc, it looks like you should have downloaded the zip archive, eh?

NVM, they seem to have rectified their problem. Carry on...
