T maxx hv conversion

[lincpimp]

Time to do the diffs! I am going to adapt a set of aftershock/lst diffs to the maxx bulkheads. Got the idea from another member here that used muggy diffs (same thing). Found a 1/2' pvc coupler that fits into the bulks well. It is tapered so that it will not be able to come out of the bulk. I need to enlarge the inside diameter to match the aftershock case, and cut the coupler to length so that it takes up the slack between the diff and bulk, as there is a small amount of play. I will also enlarge the inside of the front diff support (stock traxxas part) so that it fits the nose of the diff case. Heres a few pics, including the motor on mike's revo mount and my 2 5s batteries. Yes that is masking tape, I made the packs myself and prefer to use tape over shrink. I may clear shrink over this for even more protection.

Just finished installing the rear diff. Not really diffincult, just time consuming. The pics below should give you an idea of how it was done. Had to cut the pvc coupler to the correct lenght and press it into the bulk by hand. When you have the size correct, enlarge the inside diameter to fit the aftershock diff case. Also make sure that a revo driveshaft can fit thru the outside with some slack, as it will sit inside the pvc slightly. Then when it is in there trim the excess that sticks out flush with the bulk. You will have to cut the notch that is used for access to the driveshaft pin, but it is easy with a hobby knife. The front support has to be ground out on the inside to fit the nose of the aftershock diff case. And it will have to be notched to clear the diff case screws. Lots of test fitting involved, but I did it right the first time, with no redos.

Its all your fault. Now that my maxx has beefy diffs I can finish it up! I have about 4 other maxx trucks that may get the diff mod too!

Keep up the good work Linc!

I may be following in your footsteps on this one really soon.

What gear ratio are those diffs? If I recall correctly, they use the 43 tooth spur and are 1/8 size.

Will the spiral 43 tooth ring and 10 tooth pinion fit these?

Looks like a 8mm pinion shaft with 6mm output shafts.

Thanks Sike!

The diffs have 43/13 gears, and I see no reason why the hb truggy gears would not work. I have a spare hb diff somewhere I will try it out in the case (factory al cases cost 10 bucks each!).

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.
