Differential Dimensions?

Nope, I hadn't checked Savage Central - so I just ran over there and checked out their E-Savage forum. It's pretty small, and no new information that I haven't already seen or experience via E-Savage.com. :-) Thanks for the pointer, though - I didn't even know that Savage Central existed; how sad is that?

FLM does show diff cups for your E-Sav and they mention a full diff upgrade that uses the nitro Sav diffs, so there is help out there. I did not see much over at Sav Central either - I'm registered over there, but they can be pretty snooty so I don't spend much time there anymore.

It would be nice to find some info on what others are doing about the probs you're having. Check some of the big boards out too like Radio Control Zone and RC Universe.

I'm always amazed at what I can find using a search engine!!

Where did you see the FLM diff cups? Their E-Savage product page only lists extended TVPs:

I know about their GP Savage conversion that uses the E-Savage transmission; a couple of people over on E-Savage.com have that conversion and like it. That's available on addicted2rc.com:

If I'm going to convert a GP Savage, though, I'm just going to get the new conversion package that has been discussed on this site extensively already.

As for other sites, every time I search for E-Savage info on anything other than E-Savage.com, I tend to find people who haven't really upgraded the truck. I think that's actually a good thing - the truck doesn't seem to be able to handle upgraded power, but is a tough and speedy little thing with the stock motors. In retrospect I probably shouldn't have installed the brushless and instead just gone to 7 cell NiMh's and been done with it. People break the driveshafts a lot, but I fixed that by mating Tamiya TNX MIP CVD dogbones with MIP Maxx axles. Some people break the center shafts, but I fixed that by designing a custom extended set of TVPs, and using the UE titanium dogbones front and rear. I've also melted three spur gears, so I drilled out an Integy steel GP Savage spur and use that instead. I guess the only weak links that are left are the diffs, hence my problems.

Is it too much to ask to have a truck that can run brushless and not break anything unless I smack it into a tree?

Unfortunately, you're right - I went to addictedtorc's site and saw the cups when I clicked on products for E-Savage. I assumed they were for the E-Savage, but now I see they're not direct replacements.

If the MT-2 pieces fit, then these guys sell a alum diff cup -

Sounds like if you're sticking with BL, you don't have many choices to solve your diff probs.
