Now I got my own MI3 too...lovely peice of kit

Discovered an interesting thing tonight; compared the 6 cell chassis vs. the 5 cell version and as I expected, the 5 cell version was heavier (3,7 grams to be exact), but what surprised me is that the 5 cell chassis is 5mm wider than the 6 cell chassis. How come? Guess it has something to do with balance, but it still puzzles me a bit.

Yes, the batteries are 3mm further out and about a half cell further back. This is to get the corner weights equal and the fore-and-aft weight bias we are looking for

PW...thanks for your hard work and sharing with us your set-ups...especially the RROC '07 set-up...its really good- I just wonder if you have tried or will be willing to try working on a great set-up for those who run their Mi3's on asphalt w/ rubber tires, but use Lipo packs, instead of the 5/6 cell nimh. As you know, the Orion 4800 pack is 257g, compared to a 440g IB 4200 6 cell pack, and using the Lipo pack will definitely call for a bit different set-up than those running the heavy 6 cell nimh packs.

Unfortunately there is very little club racing in Tampa and I normally take the weekends off from R/C anyway. When I do race it's bigger races and they don't allow LiPo. Keep in mind my RROC setup is for 5-cell which is a little lighter anways

However, Adrain ran his car with the new Schumacher Core-RC LiPo last month and didn't change the setup at all and his car was really dialed

So far, in the built, I've gotten to the drive shaft which, i'm afraid, is rather poorly built. No lubrication had been used and too much threadlock had resulted in completely jammed up drive shafts. All of them. In the process of prying them apart which aint easy due to all the threadlock.
Why not just include them unassembled when everyone disassembles them anyway?

Other than that it's going fine

We didn't no about the loc-tite issue until they were "all" assembled. It took more than 24hrs before they dried and bound up. The people packing the kits didn't know any better and away they went. The problem is resolved with the loc-tite and pins and they should be back in stock very soon.

thanks alot for the help.i really value your oppinion on this issue.
Actually it's not as serious as you may think. We find it very common for off-road racers (like yourself) to get their diff grease and KY bottles mixed up. Clean out your KY oil and rebuilt your diff using the proper diff grease.
