Petition for FLM diff cup - RC-Monster Forums

BrianG · **Petition for FLM diff cup -** 03.23.2009, 09:48 PM

I emailed FLM today asking if they had any plans to make an aluminum sealable diff cup for the Slash. I pointed out that the stock one leaks like crazy if you use any kind of oil thinner than 10k, and the outdrives are rather wobbly.

They responded saying that they have considered it in the past, but were unsure of their popularity. They also said they would make them if they would sell.

So, I figure I'd try to get a rough idea of who would be interested. Once I get enough "votes", I'll respond with a link to this thread showing the potential interest. And, since the Slash diff is basically the same thing as the Rusty, Pede, etc, it could be used there as well.

Anyway, just vote/post if you'd seriously be interested. I don't know the price, but knowing FLM, it would be decent and high quality.

screw redisinging the traxxas diff, base it off of the sc10, 1/8 buggy style diffs

Yeah, well, let's start simple. The Slash really doesn't "need" an 8th scale diff (but would be nice), but the stock diff really needs some work. Even doing the mod to seal it won't address the wobble on the outdrives. The Slash has this wobble and so does my son's Pede with a brand new diff.

Spider, spider, spiderrrr!!!!

I would buy 2...

OZ-RUSTLER · 03.24.2009, 12:48 AM

I'd buy at least 5 if they were under $40.

Got my vote.

my main issue with the slash diff is that the weight of it is supported by the output shafts, and not by the diff cup. alot of traxxas' designs are like this, and it causes the wobbling issue and premature wear. i would like to see a design more like an 1/8 diff, scaled down a bit, with the cup /case supported byy bearings. this would require the tranny case resigned to accept larger bearings, and a completely cusom diff, internals and outputs. not sure if flm would make that, but i would definately buy a handful of them. they already have the tranny case, so altering it to allow for larger bearings would not be too bad. making the cup with the gear on the outside, and finding suitable internals would be more work, and i am sure that they would have to be custom made...

Rc-m and swami-rc already have full metal diff cups for the slash etc. Redesigning these would probably be faster/cheaper than for FLM to make a whole new diff.
And you could also try MIP's ball diff if you want adjustability. Haven't seen any reviews on them yet.

I knew swami had one, but when did Mike make his?? I could have sworn I looked everywhere and only found the swami version (and it was a bit pricey). Hmm, now debating about closing this thread since I definitely don't want to compete with Mike, but he carries FLM...

Redesigning the outdrives so they are supported by bearings (similar to an 8th scale) would be a good idea, but would probably involve modifications to the tranny. So, not sure how much of a good idea this will be after all...

I would FOR SURE by one for my rusty.....no doubt.

(especially if it had bearings in the out drives, but I would want it to fit in a stock tranny)

They're both picey, $85 for rc-m and $75 voor swami.

BrianG · 03.24.2009, 10:08 AM

Yeah, I went and saw that; I was just wondering when he had this in stock...

TexasSP · 03.24.2009, 10:36 PM

I thought the one Mike sold was FLM?

BrianG · 03.24.2009, 10:51 PM

Well, judging by FLM's email response, I guess not. Besides, Mike usually only puts his rcm logo watermark on his parts.

i think as much as this is needed, better-hardened planetary gears are also needed. or something like an MIP racing diff but with a steel diff gear.

if i run anything more than 3S, i can turn them to dust in about 2 minutes if i'm running a tight slipper.

Thankfully, a member had a very few sets of these gears made from a much stronger hardened steel that has been unflinchable on 6S on XL motors and even on the neu 1515 1Y, 2650, and 2200. why dosen't anyone mass produce these? i can't tell you how many people are always bit$%in about busting up these in the traxxas forums. i'm all for any trans mods.
