Speed Calculator

[MetalMan]

I use 3.5 usually, for a best-case approximation.

[BrianG]

Added LST tranny ratios, LVC diagram to the wiring page, and a couple other small changes.

Someone requested entries of these 18th scale vehicles:

- Associated RC18T/MT/B
- Associated RC18MT PRO
- Kyosho mini Inferno ST
- Kyosho mini Inferno ST PRO
- Xray M18MT
- Team Losi Mini-t

However, I don't really feel like looking up the various tooth counts for these, so if anyone happens to know any of them, let me know and I'll add them.

Link is in my sig...

Very cool - Thanks for the LST stuff and the tech support on the calculations too. Keep up the nice work. It is definitely appreciated.

[BrianG]

No problem. I have to make sure it's full-featured now that it's a stickie! :)

I was looking at the web referrer stats for my site and noticed that it's making it around to a few other R/C forums: www.lstforums.com, 30486.rapidforum.com, and www.maximummt.com. I thought that was kinda interesting for something just pieced together...

[riceman]

I know I 've linked the Calculator a few times over at lstforums.com:) Very interesting though with maximummt.com. Is it a Canadian site?

[Serum]

yup.. it's there for sure.. well hidden in a roll-down menu.. :p

It even has the rcmonster.com in front of it to.

I just tested My setup with your calculator and a radar gun:

Gorilla racing G2R
18/51
9XL
Mamba Max ESC
4s LIPO
proline bowtie 40 series tires with wabash wheels (5.8", according to proline)
Emaxx tranny half tranny conversion
revo diffs

according to your calculator, it showed 30.65MPH at 3.7v per cell, radared it today at 30MPH (doesn't do decimals) with a bushnell radar gun, so i guess you're calculator is set very good, now it looks like i can run setups with confidence

[MetalMan]

crazyjr, did you factor in any tire ballooning? It looks like the approximate speed is so accurate because you accounted for tire ballooning by putting in a higher voltage (the cells are probably closer to 3.5v).

[BrianG]

OK experts. I added another section for lipo wiring. It's in "beta" stage, so you can't access it from the menu and some parts may not be fully done. I just want to know if this makes sense and will be of use. If so, I'll finish it up.

It also looks like I'm going to have to come up with a new menu scheme since the text links are getting too wide. Maybe a menu system something like this for bling? (my old home page. Don't laugh, it's old and hasn't been updated in a REALLY long time). Or should it stay simple?

I think you should dress it up with some carbon fiber. Maybe some rc-monster logo's somewhere? Just a thought...

OK, I can dress it up somewhat, but I don't want to make it look "busy" or hard to read with complex background images, especially patterns like CF. Maybe if I faded it so it was lighter...

BTW: I just uploaded an update for the lipo page. It appears I named a function to a built-in function and there was a clash. Fixed now, and works better. :)

No i didn't, just factored 5.8"diameter according to Proline

[BrianG]

OK, new version uploaded with the final lipo page. Whole new menu system and minor changes to layout as well.

@cemetary gates: I used both CF and the RCM logo. Although it did take a while to wipe out the background...

@MM: I used some of the code from the BEC & Wiring page to show how to connect multiple packs. I hope this is sufficient.

As usual: R/C Calculations

Looks really good!:027: I'll have to bookmark the new version...
