Hot bodies 1/8 diffs

I'm not sure if there is something wrong with the new universal mount. The top plate seems to be to long, and I'm not sure if the mount was made to be used with the 65t gear. Any suggestions? You can see the gear hitting the side of the mount, and the top brace is too long.

Well, I got a response from mike. just sent him an email, and 50t gear is the largest that can fit I just put in an order for the 46t gear and a few mod .8 pinions. I will play around with the gearing to get something similar to or better than the stock gearing.

It isn't too long, you need to use special inserts on either side where the bearings go in order to space out the front and rear upright parts further; the Slipperential is somewhat 'shorter' than a regular 1/8 centerdiff.

65tooth spur gear is massive though, you would normally only use such a gear on a transmission with an 18-24tooth pinion- with a CD, gears in the 40-50tooth range as what you should be using really with 9-16tooth pinions at most.

I suggest contacting Mike about the required custom spacers- the unit is designed to be universal but it wont necessarily be as simple as drop-in & go..

EDIT: Are you sure you need mod0.8 ( 32pitch ) pinions- the listed 46t & 50t spurs for the Slipperential are MOD1.0, so you need MOD1.0 pinions to match.

Thanks as usual Neil. I thought I saw somewhere that the stock uses mod0.8. I will email mike to let him know.

Got the right gears coming (mod1.0....thanks Neil). Mike is also sending me the right length upper bracket, and I also waiting on a few more major parts that should be shipping today or tomorrow. I have RPM shock towers and a-arms that I was going to use, but I am now going to go with another option.

Does anyone know where I can get a pair of Gorilla maxx straps? Would the Gorilla Maxx carbon fiber brace work (G2-X brace)? I know my chances of getting either is pretty slim but if I came across the carbon fiber brace I would like to know if they would work.

[suicideneil]

I think the CF straps are designed to fit a very specific length of battery tray since they attach on top of a post either end & are secured with a body clip- chances of the FLM chassis having the same holes in exactly the right places is remote.

As for the velcro straps, they were nothing but overpriced regular straps with the GorillaMaxx logo silk-screened onto them- paying $20 for a couple $2 straps is crazy ( probably why I have 4 on my GMaxx ). A much cheaper and stronger option is to make your own straps using something a bit more heavy duty, like so:

Very simple concept and lets you use any regular straps- you just need 2 per battery tray, quick google for 'battery straps' turns up loads of cheap options.

[cmac]

Very cool idea. Thanks, I found a place in Europe that has both the Gorilla straps and the CF brace, with the exchange rate the straps and shipping worked out to about 74 dollars U.S. and the brace came out to about 110 dollars U.S. that would have been an expensive mistake.

So i received the new upper bracket for the cd mount today. I also got the 46t spur gear. I was hopping that the smaller gear would fit between the opening on the frame. No such luck. I guess I will have to do some work with the Dremel, unless there is another way. I can't be the first to try to fit a Slipperential to the extended FLM Maxx? Are there pictures of it mounted without having to hack the frame? I don't have a problem doing it, but if I have other options I will try them first.

[suicideneil]

The trouble is the new emaxx tranny is narrower than the old one, so the chassis rails are closer together as such- was never much of an issue on the older style FLM chassis for the 3906 tranny, but with the new chassis you don't have any option besides notching the chassis rails either for the spur to fit. On the upside, it should be very easy to do a neat job- just hacksaw or dremel the notches and then clean them up with a small flat or square file.

[cmac]

That's what I will do. I should have waited to do the anodizing until the end of the build. Oh well I'm learning as I go along.

Rebuilt the slipper with the 46 tooth spur, notched the chassis, and everything fit perfectly. I need to drill the holes and mount the slipper next. Then I need to figure out how long the dog bones need to be. Neil do you or anyone else know how much Mike charges to make custom dog bones?
