Differential parts for FLM hybrids

[extremexmods]

Got a set of the FLM Hybrid bulks (requires 1/8th scale diffs) for my e-maxx just have a couple questions about the internals
http://www3.towerhobbies.com/cgi-bin...?&I=LXPLV9&P=7
would these work for the differentials? Does this also come with the center outdrive which goes between the differential and the center shafts to the transmission, or do I need to also purchase http://www3.towerhobbies.com/cgi-bin...?&I=LXDLD3&P=7 as well?

bearings: what bearings do I need to get? I see the differentials come with bearings, are they the proper size when used with the FLM hybrids or do I need to get different size bearings, if so which ones do I need? For the outdrives to the center shafts I believe the outdrives are not included so I probably need to get them too, therefore what bearings do I need?

Drive shafts: Maxx miv cvds all front rear and center. Do I need different output cups or will the current output cups work with the savage differential output shaft?

Shims: what size shims do I need? Do I need to shim inside the differential cup where the spyder gears are or just the left/right sides between the differential as well as outdrive in order to old the mesh with the ring gear?

I would stay away from HPI diffs in general, too many drawbacks IMHO.

The ones you linked are the old ones with weak ringgear and bevelgear.
Another bad thing about HPI diffs (all of them, also the newer "bulletproof" ones) is that they use weak 10x16x5 bearings on one side.
Most 1/8 scale diffs have stronger 8x16x5 bearings on both sides.

For the bevel gear you usually need two 8x16x5 bearings as well.

The older HPI Savage output cups are made for dogbones with around 9mm ballends, the newer output cups (Savage Flux, XL) for bones with around 11mm ballends. However, most (if not all) other 8th scale dogbones or CVDs have 8mm ballends.

If the Savage diffs are known to fit inside the FLM bulkheads, I would go for CEN GST 7.7 diffs, since they fit the Savage, they should also fit the FLM bulkheads then I guess. They are completely indestructible. Drawback is, that they are quite heavy.

http://www.ebay.com/itm/Hyper-7-Fron...item20e617a273 would these be better? I believe these are the diffs UE uses in their ultralites.

http://www3.towerhobbies.com/cgi-bin...?&I=LXCVT8&P=7 this is the gear leading to the center shaft? what size bearings for this diff?

What you linked to are the "Super 8" diffs when UE sells them.

Here are "Super 6" diffs, with bearings and a pinion and everything you need for much much cheaper- http://www.ebay.com/itm/HoBao-1-8-Hy...item4d1e8e2aef

I have ran very high powered setups with the "super 6" diffs, and in my opinion the extra cost isn't worth it to upgrade to the "super 8" diffs.

To answer your question the bearings are 8x16x5. What you linked to will work fine.

Will those "Super 6" diffs you linked to work in an LST diff case? I have LST diffs in my REVO and want to have some replacements just in case. Or is there a case they would fit in that would fit in a REVO/Maxx?
