The 6mm outputs are mike's output adapters. I will run the new emaxx driveshafts you are sending me! pinion is 8mm and I will run a set of mike's adapters to hook up revo sliders as center driveshafts.

The chassis will need to be clearanced so that the rear driveshaft will fit. I may be out of luck with the revo motor mount. I may have to make a different lower mount that will clear the driveshaft. I will take a pic of my proposed setup and we see what it looks like.

Yes would you Please check to see if they fit for me? I would really appreciate that. That's amazingly cheap on the cases. Did you get these from Ebay?

You know what this makes me wonder about don't ya? Could there be an affordable way to create a Direct Drive to Diff E maxx?

Now that I have some motor winding "eduamacation" under my belt, I wonder if it would be possible to use a smaller diameter outrunner that would fit between the frame rails? There is only 45mm there to work with.

Smaller Diameter means less torque but higher kv when it comes to outrunners. but the Wye wind termination can be used to make up for that.

Lets see, I got the diffs complete unused on ebay for 20 each. Losi al diff cases are 10 bucks IIRC, brand new from horizon or the lhs. I do not think that the al cases are needed on a maxx, but we will see The diff case is a superior design to the maxx case anyway.

If I can find a machinist who works with plastic i may have some adapters made up, that way the diff would be a drop in, and with mikes input and output adapters a complete setup. The plastic adapters would not cost much to make, a lathe would most likely be the only tool needed. Maybe a mill to make the pinion support? They could be plastic or al, depending on what people want.

LOL I have the same idea trying to get a price on making the adapter out of aluminum, ill let you guys know if I do make a run of these for parts.

Oh and sikes the muggy diffs are 11/45

An aluminum Adapter would be a good idea.

I was thinking I seen a 46 tooth ring somewhere.

A 10/46 setup would be something good to work with.

Did a little work today, got the front diff installed and am looking forward to the mail tomorrow as it has the diff output shafts, adapters for the 8mm pinions to use revo shafts, and a set of driveshafts. If all goes well tomorrow evening I should have a complete roller. I am thinking of flipping the chassis over so that the batteries trays will fit flush, right now the chassis bends up slightly on the sides, and that is where the edge of the battery trays will be.

you ever thought about a planetary gear box on both ends?

ive been trying to read up on some.

[suicideneil]

Thats an idea that hasne been discussed much, but is worth looking at. feigao sell strong planetary reduction gearboxes that are a direct fit for any normal sized motor with a 25mm mounting pattern.

Spent a few hours on the tmaxx today and basically have a roller now

Anyway, I have flipped the chassis over for better battery tray mounting, extended the chassis cutouts to make room for the revo center driveshafts. I used the really short revo 2.5 center shaft as the front driveshaft, and used a stock length wheel driveshaft for the rear center. I also modded the aftershock diffs to accept the rcm diff output adapters (drop in fit with the diffs) and the 8mm rcm driveshaft yoke for the diff pinion (required a little grinding for a perfect fit). Then assembled the arms and revo bearing carriers, using revo driveshafts. I also installed a set of blue ofna 17mm hubs.

Next up is to fabricate a set of battery trays (easy) and a motor mount platform (not so easy). I would like to use the rcm revo motor mount, and I have one and have been very happy with its performance and design so far. The only issue is that it may contact the rear center driveshaft, so I need to raise the base of the motor mount, while still retaining a solid mount. I am thinking some sort of bridge actoss the rear chassis cutout, and attaching the revo mount to that. I do not want to add too much weight, so I may make a new lower portion of the revo mount to bridge tha gap.

Heres some pics:





Now for a QUESTION: Does anyone know what linkages to use for steering and rear toe rods, as the tmaxx ones I have are too short. Do I need to buy revo links?

[squeeforever]

You need T/E-Maxx 3.3 ones. Revo won't work I don't think.

[sikeston34m]

Linc, This is going to be an Awesome Conversion!

Is that the modded 1/8th diffs I see peeking out from in between those bulkheads?

Yep, did some research and found the part#s that i need. Should be 5141 5143 5347 and 5355. That covers the two different length rods and the pivot ball/spacers.

Thanks Sike, just need to make up a motor mount and battery trays and it should be ready to roll. I will try to get the steering and brake servos hooked up tomorrow, and maybe the bumpers, etc. I just ordered all 8 shocks, 28 bucks inc s/h from fleabay! And I should have the esc and prog card next wed. This project may come together sooner than I planned!

And yes, those are the aftershock diffs hanging out in the stock maxx bulks. This drivetrain looks very solid! Hope it can hold up to the 20xl on 10s!

What kind of shocks did you get?

Just the stock grey 3.3 ones. I have had very good luck with the stock shocks on the maxx. I only bash, and my driving skill is good enough that I rarely ever break anything. If I do anything I may add the al shock caps that traxxas sells. That said I knocked the lower front arm of the crt.5 tonight, but I was driving blind in the dark!

I do believe we have some things in common. LOL

I got so anxious to play with my Revo the other night but it was dark.

I have a quantity of those 9 LED flashlights. You know the ones that take the 3 AAA cells?

I strapped two of those flashlights to the front bumper bracket and made headlights.

It worked. I was able to enjoy my run and have my fun for the day. Was probably freaking the neighbors out a little though. LOL

I have a few of those. We actually took on and strapped it to my mini lst (crap by the way) and slowly drove it around the vacant lot across the street. A bunch of people saw the light moving around and could not figure out what it was. I was hiding behind a bush, so they did not see me. Great fun, especially when one person went after it, good thing it was brushless, and good for 30mph, or he may have caught it!
