Argg! Can someone verify this? Something like:
Matrix TR RTR: ?
Matric TR FTE: ?
Matrix buggy RTR: ?
Matrix buggy FTE: ?

OK, I really don't want to download the PDF and figure this out. So could you list all the gears used for each speed?
LST 1st gear: ?
LST 2nd gear: ?
List the gear pairs like so: output/input, output/input, etc. Similar to how I have the revo tranny listed in the calc. That would be the most helpful to make sure I have the right data.

And yeah, I'll add the Mod1.5

Yeah, what _paralyzed_ said. I'll differentiate between the two somehow. Might just remove the existing one or something.


So, a summary of the list of changes:

- Add Hot Bodies D8 diff: 43/10

- Sort out the LST tranny ratio

- Remove V1 Slipperential (or somehow note it is V1)

- Add V2 Slipperential "transmission": 1:1 (since there is no actual transmission).

- Sort out the Matrix ratios between the buggy and truggy, and for the RTR and the FTE.

- Add Mod1.5 gears to the diameter calc.

- Add brushed motors for crawlers:
10t = 6526 rpm/volt
15t = 4317 rpm/volt
17t = 3753 rpm/volt
20t = 3216 rpm/volt
21t = 3082 rpm/volt
23t = 2790 rpm/volt
25t = 2588 rpm/volt
35t = 1565 rpm/volt
45t = 1210 rpm/volt
55t = 987 rpm/volt
65t = 837 rpm/volt

- Add Berg and Clod ratios:
Enroute Berg: ?/?
Tamiya Clod: ?/?

Is that it? People have a tendency to come up with other things after I make changes and upload the new version. :no:

FRE truggy/buggy- 11/38
Standard Bugyg truggy 9/26

Could you add a clod and a berg into transmission - pretty please along with maybe some brushed motors 35t, 45T, 55t, 65t? pretty please with a cherry on top

Going for worlds fastest crawler chris? :lol:

I'm running the berg with 35T on 3s and 13t - Its pretty nippy...

Debating on converting SPV2 to a rock racer but son likes going slow...

Hmm. I can add the tranny/diff ratios as long as you provide the gear tooth counts. However, I am hesitant to add brushed motors; they are so '90's. :smile:

Hello BrianG can you put me in the right side please.
When I use your Speed Calculator I know all the field except the ballooning field I'm not sure what i put there.
for example i use MT badlands tires + 42 mph speed so with setup what should i put in the ballooning field

Thanks

btw: why you dont add a page for ESC's info.. just like charger's table info that you have there

Berg 36.67:1
Clod 30.1:1

Ballooning depends on the tire. I am not familiar with all types of tires so I can't really help you there. But, what I do sometimes is pick the vehicle up so no tires are touching the ground and give it full throttle. Then I try to estimate the amount of ballooning that way. And use the added radius as the ballooning value:

And I was actually going to remove the charger data. It's difficult enough to keep track of all the CD/tranny ratios and motors. The charger data really has no use there except to auto-fill the fields in this page, and that list is really out of date now. ESC data would be even more irrelevant except to be able to compare specs side by side. It would be much easier to have this database driven, but as this is cleint-side script driven, data entry is cumbersome.

From holmes

10t = 6526 rpm/volt
15t = 4317 rpm/volt
17t = 3753 rpm/volt
20t = 3216 rpm/volt
21t = 3082 rpm/volt
23t = 2790 rpm/volt
25t = 2588 rpm/volt
35t = 1565 rpm/volt
45t = 1210 rpm/volt
55t = 987 rpm/volt
65t = 837 rpm/volt

What motors are those numbers for? Any normal 540 size motor? That is if I decide to add them. :wink:

Umm, tooth counts? And as I am not familiar with those vehicles, specific makes and models would be helpful.

Enroute Berg and Tamiya Clod

No idea on teeth - too many...

lol, well, I'm not gonna count them! I use tooth counts to prevent rounding errors as much as possible.

The stock Berg ratio assumes a 12T pinion. Not sure about the other gears.
