Brian,

How are you? I sent you an e-mail (To your hotmail address listed) about something cool that would be great for everyone.

Do you know how much HP per ton your little R/Cs make?

My BPP truggy made over 600HP per ton. While my Mr. C MBX5T has made over 1200HP per ton. Isn't breaking the 1000HP per ton a great achievement in the auto industry? Does this mean our little R/Cs (Many still consider them toys) are more efficient and advanced then the 1:1 available.

Regards,

Luciano.

I suppose that could be done. As you said, there would be a LOT of additions. If there is enough demand, I can do it.

Emailing/posting the values is the only way for the data to get input into the calc because the whole calc is client-driven via jscript arrays. This is mostly so I can develop "offline" and people can download and use it without internet access. Having people add the values would require server-side code and would make it a whole lot more complex.

lol pretty simple really, but not sure exactly how much use it will be? Would be more of a "neat" thing to have. Your link is for PHP code, but that kind of thing would be FAR better to be done in the client. Why make a server trip just to calculate a simple value?

For HP per emperial ton: (HP/lbs)*2000
For HP per metric ton: (HP/kg)*1000

Brian,

Would it be possible to include the new Slash 4X4 in your Calculator ?

it used the revo diffs...

Where would we be without your keen observation ??

Thanks Brian !

Update:

Due to my issue with the Ten-T spur; added gear pitch calculator (finds pitch with gear diameter and tooth count inputs) to the Gear Diameter Calculator page.

Added Traxxas Slash 4x4 spur options and differential ratio.

Added Losi Ten-T differential ratio.

Your awesome Mr B., Thank You

Update:

Added a new page, Dogbone Dimension Table, to help users select a possible existing dogbone for custom setups.

Currently, the only entry is a test entry just to have something there. Please post the values as shown in the page and I will add them.

I don't know how you'd do it but a provision for shafts like the LST center shaft that have a CVD on one end would be nice.

Maybe the length from pin to grub screw and the size of shaft the CVD fits on? (8mm for LST)

I love your site Brian! I got around to using your no-spark calculator on my e-bike. I got a HUGE spark with my 18s turnigys; now I get a lil tiny spark. :smile:

I used a tiny resistor off an old futaba tx board; I didn't expect it to work.... It worked perfectly!

I only have one question/concern

Should I have a diode wired in or disconnect my no-spark circut after I get the main leads plugged in? Someone on another forum suggested it saying my resistor would burn out if I left it plugged in.

When you hook the main leads together, you are effectively bypassing the resistor so all the current flows through the main leads. The only way the resistor would burn up is if the main leads became disconnected during use and all the current tried to flow through the resistor. However, there are a number of reasons why this won't happen with anything larger than ~50 ohms, but won't get into that here. If you were using something like a 1-5 ohm resistor, then yes, there exists a chance it could burn out, but again, only if the main leads became disconnected.

I have a few to add. The XTM shaft was too long for my calipers hence no decimal but I will let you round of the other figures.

XTM front centre swing shaft-
D1- 182mm
D2- 175mm
D3- 5.02mm 0.97inch
D4- 3.03 0.119
D5- 7.84 0.309
D6- 13.83 0.544

LST1 axle-
D1- 143.6 5.653
D2- 135.11 5.319 CVD end
D3- 4.4 0.173
D4- 3.03 0.119 2.51mm 0.1 inch
D5- 7.79 0.306 10.75 0.423
D6- 13.75 0.541 13.93 0.548

RC8T rear centre cva-
D1- 136.91 5.39
D2- 128.12 5.044
D3- 3.7 0.146 CVD end
D4- 3.00 0.118
D5- 7.81 0.307 10.52 0.414
D6- 11.7 0.46 sorry haven't measured it yet

I hope I have done all that right :oops:

Panda: Thanks for that info! I assume the LST1 and RC8T are CVDs, and the XTM is a true dogbone?

Looks like I'm gonna have to add a seperate center CVD and CVD axle sections or pages. Otherwise, those measurements won't make much sense when applied to the current dogbone picture. Does anyone have a good clear picture of a center CVD and an axle CVD? All of mine are in vehicles and are not in "picture condition". Ideally, a clear, large (bigger is better for me to edit), well-lit image with a white background. PM me if you have pictures and/or can take some and I'll supply my email addy to send them to.

BTW: I am adding the following as a note to myself since my development PC is off and I don't feel like turning it on just for this:
Ofna Hyper 7 F/R:
D1: 97/104
D2: 90/97
D3: 4.8
D4: 3
D5: 7.9
D6: 12.7

it would also help to know what xtm those are from.

I tried to put spaces in to make it look like columns but the post didn't come out that way :whip:

Yes the xtm is a true dog bone and the others are cvd's. I'll attempt some photo's for you tonight but my photography isn't good :mdr:

Only the first is xtm- mammoth part # mv3559. I saw on the interweb it was 192mm but when I got it in hand it said 182.5mm. I don't know why there is a difference???:neutral:
