check em out, looks pretty interesting to me.

[Serum]

Thanks!

i was searching for them, but i kept landing in their commercial.. :)

Check out that diffs.

@Serum

What's your opinion of the overall makeup?

I like the transmission. I'm pretty excited about that. I haven't been able to find any info on the 2 speed "kit" that they mentioned yet.

The diffs look alot beefier. I hope they used a tough cup, and improved the spider gears. On the old version, One of the weakest points were the 2mm screws that held the ring gear to the cup. If I'm reading that right, these are 2.5mm screws

[suicideneil]

2.5mm? Thats just plain odd. Still, should be easy to upgrade it to 3mm if required. It would also be nice if GorillaMaxx did come out with a revised chassis- new rails & front upper plate I imagine to accomodate the tranny and servos, then stick the esc & rx down the rear end (oh-er mrs).

Theres nothing wrong with the stock Emaxx tranny, once you've stuck an RCM steel idler in there & replaced the weak roll pin holding 1st gear onto the input shaft. But, yes, I want a nice centrally mounted motor too. Damn Im fickle sometimes.....

[sikeston34m]

The upgraded "original" E maxx tranny has disappointing limitations.

I run an upgraded input shaft, and RCM steel idlers. The next weakest points are the plastic output gears and the drive dog.

On different occasions, I've stripped each of the lower output gears. I've broken the teeth off the drive dog that engage with the output gears. I've also stripped out the hole in the drive dog where it rides on the output shaft.

The plastic gear teeth are weak. It's not that hard to shear them off.

I don't think the plastic can take the heat from being spun so fast. The material gets soft when you push it the hardest.

I even tried talking to a machine shop about getting steel ones made. The originals are metric, hard to identify and hard to acquire gear stock for. So I ran into a dead end on that venture.

I'm VERY excited about a transmission that is 2 1/2 times stronger than stock. The stock one isn't bad, but it comes apart when you exceed 50 - 55mph or so.

I'm DEFINATELY looking forward to putting this new transmission to the test.

I've been using these Ebay gears in my E-LST since the Tranny was in an E-Maxx without any big signs of wear. Unfortunately, that ebay guy never wanted to tell where he got them or which machining company he asked to make them.



But maybe I shouldn't advertise them so much since I've never went over 50mph (40 at most)

[sikeston34m]

Are those the ones that are advertised as Titanium?

I've asked a few questions of the guy selling them with no response. That tends to steer me away if they won't communicate. IF it's the same guy.

I could care less about the centrally mounted motor. And the problem with the stock Emaxx tranny is that it doesn't have a real slipper. As far as I am concerned if it doesn't have a Revo type slipper then its useless. In other words, stock Emaxx tranny = useless worthless piece of crap.

Fair enough. I assume that the new Revo-type slipper can actually take Revo spurs though - MOD1 pitch- , judging by the design of the slipper pads & the screws etc.

It's too bad that the tranny couldn't be sealed so that you can run some thin fluid in there to help with the heat.

What about venting the tranny case? Cut some holes and then glue in some metal screen (like in a screen door) to keep debris out, but get some airflow? Either that, or simply run a center diff instead of a tranny...

[sikeston34m]

I've had some pretty good luck in sealing the tranny. That's another mod I always do.

I use silicone on the mating surfaces during assembly, then use rubber sealed bearings on the output shafts.

I haven't experimented with different vicosities on the lube, but I use Lucas oil stabilizer. I think maybe it's a little thick, but seems to work good for gear oil.

I don't think I want to vent. Dust and abrasive material is the enemy of gears and bearings.

Before the new E Maxx info was released, I was pondering a FLM case to dissapate heat and all steel gears. I think I'll just start with the new E maxx instead.

I can understand that, but people use exposed center diffs all the time with rare issues. As long as the bottom is vented to let any small debris fall out, I don't see where it would be a problem.

It looks as if the trans may have same mounting style as a revo trans.
