Hybrid Diff Instructions for Review

[Arct1k]

[QUOTE=Sammus;219662]In the diff selection section, I think in the table you should have "Top Speed with stock pinion" or something to that effect. I think it could be a little confusing to some people.



There is no such thing as a stock pinion really ( i quoted the setup I based it on) - The only other thing I could do it is show it was a % that you need to gear up and then include some examples ie. 9T now needs to be 12T etc

Not sure I will change it but any preference for next time?

Shaun - Thank you very much for the pics

Thanks Linc - I'm sure mike isn't doing anything special except I think they are the hardened gears... will update to reflect

George16 - Thanks for the shimming lincs I will reference those - i couldn't find a good one searching on google - the tmaxx one is all I found - The process on Tmaxx one looked correct but agree that telfon's not going to work too well on buggy/truggy diffs.

Well stock may not have been the right word to use. Looking at the page as if I wanted to build the diffs (which I eventuall will), I did as I do with many manuals - scan over the text until I see something that stands out as important or interesting. A lot of the writing is (and this is no exception, and is not a bad thing at all) standard description and other formalities that not everyone will read in the excitement.

At first glance, I saw the table. I saw "diff ratio, top speed, pinion required for 41mph" and it took me a few seconds to realise the 'top speed' column was the top speed with the "standard" gearing (ie the gearing in your example setup). It's far from major issue though, and I doubt anyone would be seriously hung up on it.

I guess the point is there should be some qualifier next to top speed, because unless you read it thoroughly (which of course you're meant to, but unfortunately most people don't) it is initially confusing having a top speed written next a column suggesting pinion choice for a particular top speed.

Not sure I will change it but any preference for next time?

Again nothing overly important, more aesthetics than anything. What drew my initial attention was on the second page you say "The following picture shows the layout for the....differentials included..." and I wasn't sure which picture you were referring to. 'The following picture' I think could mean the one next to it or the one beneath it. It doesn't really change the meaning of anything, but it made me stop and think about the layout.

Final Version unless anyone spots anything very wrong...

[Sammus]

Cool. Except where does one find a 26t or 33t pinion?

It may be a good idea to add something about the pinion/spur ratio, and that you can also choose a smaller spur and not such an enormous (impossible in this case) leap in pinion size.

I guess this is hardly a gear selection tutorial sheet, but if you say its good to change the gearing if swapping in a lower ratio diff, then recommending a pinion size that's near impossible to get, it may be a good idea to put a word in about it. Or am I being pedantic?

Also you need to change the link to the rc-monster forum to
www.rc-monster.com/forum/

Leaving out the last back slash causes an invalid link.

[Arct1k]

Tough crowd! you can get a 25T - the 33T was to show that the gearing gets silly - The next paragraph says truggy diffs only for a novak HV setup...

Link fixed - It was case sensitive...

That is kind of the point...

Great job Arct1k, but just one thing missing, is for the front diff, when you reinstall the bulckhead on the frame, the little black plastic goodies who hold the stock diff in place have to be triming a little bit with a Dremel to give room for the new and bigger Hybrid alloy diff case.

Other than that, all is OK

Nice Arct1c!

Question: why do you say to make note of which diff is front or rear? Is it simply because of the oil differences? If that is it, you can always feel the difference in stiffness...

[Arct1k]

For the oil - I guess you can feel it but doesn't hurt to make a note...

question:
if I have the truggy diffs? can I just purchase the Hot Bodies 13T BEVEL GEAR? to make them buggie diffs? or is it not that simple?

sorry for my ignorance, I just purchased a G3R and it came these 1/8 truggy diffs but would prefer the buggy.

Yes but make sure the pinion and ring gear have the same cut. Some truggy gears are spiral cut. What brand are your current diffs?

[XSKAPE]

hot bodies 43/10 truggy diffs

Then you're good to go.

thanks for the super fast response. cheers
