it's the Tamiya (#49436) - Tamiya TRF415 MSXX Lower Deck for Stick Battery
With this conversion set, stick-type 7.2V battery packs can be installed in the previously released high-performance 2-belt 4WD TRF415MSXX chassis. Set includes 2.5mm carbon fiber lower deck, 2mm carbon fiber upper deck, and carbon fiber battery plate. Specially redesigned lightweight blue anodized aluminum rear bulkhead, rear upper brace, and center post are also included.
*Compatible Chassis: TRF415MSXX
looking at the chassis, looks like it's designed for 4-cell, 6-cell, stick type battery. will the 4800's lipo fit? the bulkhead has been redesigned so that the 6-cells and stick type won't be under the old bulkhead design.
what do you guys think?

As I know, the old one chassis(msx, mre, msxx) only fit 3200, maybe TRF want to fix this uncommon problem, which happened only with them but not with other brands chassis(as I know), so redesigned their rear bulkhead, new lower deck to joining with battery plate to be compatible with 4800 just for euro/us racers?
Anyway, just built up the 16ball diff... didn't get it right at first, was very tight. Traced it down to not taking enough material off the pulley. Whipped out the dremel again, and solved that. Now very smooth.... bedded it in a little with a pack, but I reckon after one run it will be even better

I have the TRF415MS stick pack conversion, which consists of the lower deck and the battery posts and holders. It didn't require new bulkheads since the TRF415MS rear bulkheads don't extend over the battery area. I fit a Intellect 4200 stick pack in there with a little room to move front and rear. However, the battery holders are curved exactly for a stick pack, and as such I am not sure whether a 4800 Orion LiPo would fit, but the 3200 Orion Lipo should fit no problems since they are the same shape as a stick pack.

we have sealed ball diffs now, we just use tape though. so it is light now. a light weight gear diff might be a good option to test. It will deifnately be heavier due to all the metal inside but worth a try...
1/10 gas cars used to have ball diffs... they are all running gear diffs now.
but weight penatlty as u said would be a problem...
but I can see a future in direct rear and oneway fronts

On foam with 30mm rears it could work.

hey guys,
what is the highest gear ratio achievable in an MSX with 48p gears?
cheers

You can gear over 13 to 1, all the way down to the low 4's.

49378 and aside from the MS and MSXX any other stick pack convertion chassis for the 415 whew!!! this is getting confusing

Then your IDR is 2.1875. To get close to 10, 88/20x2.1875 = 9.625. And 88/19x2.1875 = 10.132, which is closer to 10. Although 87/19 gets you closest with 10.01.

Can somebody give me the part number for the Direct Drive Pulley from the MRE? If you have any ideas on where to get it that would be great too. I'm in SoCal.
