The flux has the two speed pinion on the input shaft right? I was assuming they were going to use the 2nd gear pinion (being larger) and just place the idler differently on the shaft.

Of course I was purely speculating. Seems easier than making a new case.


Edit: Where's my brew JT?.... lol

uhhhhhh - was that yours......?!?!?

Seriously, maybe I should start a new thread to ask this question:
I replaced my front and rear bumper mounts last night, and as I was doing so, it looked to me like it would be quite beneficial, and not very complicated to come up with a better means of retaining the hinge pins, and a better bumper mount (or possibly eliminate the bumper altogether).

Being new to HPI, are there any aftermarket products that already do this?

LOL, when I was reading that '146' I was like omg, should I also start counting my runs or what :D.

Anyways, seems my diffs are still fine, just broken my front bevel gear.

@ JTiessen, I, and many others, 'solved' it by putting a tyrip around it (not to thight because otherwise it will snap), haven't had a problem since. I know TCSCrawler had a brace made for this 'problem'. Altough after some bashing and testing he found out that the brace wasn't strong enough.

EDIT : @ Finnster (below) : Sorry, I meant the same as you. The zip ties just stop them from rotating.

What exactly is the problem?

The only prob I had was upper hingepins backing out as the upper bumper mount can rotate and not hold the pins in. I put zip ties around the two bumper mounts so they can't move apart from ea other, while the clips can still be pulled off and the bumper mounts pulled out to get to the hingepins and bulkhead screws to remove the diffs.

Has your bumper mount broke then, or ripped out the clips (as NC's soln seems to imply)?

I broke the screws off that attach the bumper to the bumper mount - did it on both front and rear. And in that same time frame I snapped the left rear drive cup in half. And judging by the way the plastic is chewed up around the lower hinge pin "stop" area there is a lot of movement in those parts.
I was just curious if there were any aftermarket systems for it. The first thing I always did with my Traxxas rigs was to rip off the bumpers - cant really do that with the Savage, it appears - unless there is an aftermarket hinge pin retention system that revises the function of the upper hinge pin retainer/bumper mount.

Obviously, I must have hit hard a couple times to do it. And that flex is probably very important to absorb the impact and not drive it further into the truck. Given the speed and weight of this truck (and my driving), I would probably be smart to keep the bumper system.

I wonder if they're going to do anything with the eSavage, probably not..

Damnit...

Rawbuns- do you have to have damnit in every post?

Sorry for the threadjack guys... :lol:

When HPI doesn't upgrade a thing on the eSavage, yes :yes:

So damnit! :party:

Hmmm - but they did. Unfortunatley, you can only buy it in a complete 650 dollar package, or in parts on ebay.

:lol: Besides the Flux, as in upgrades to the drivetrain in any way! :no:

kershaw designs has a eSavage tranny. it is based off of their electric conversion tranny for the nitro savages. it is better and lighter than the flux transmission.

My tranny is still very nice, but I'd rather have better diffs, other than the GCM Twin Diffs, which cost me an arm and a leg.

I'm running 6s with the punch control set to 100% and reduced the throttle curve. I've broken 5 rear diff pinions. I made sure they were shimmed properly each time I replaced it.

I now have the CEN diffs in there. I took it out for the first time a couple weeks ago and somehow managed to crack the rear bulkhead where the pinion comes out. I wasn't even driving it hard. The rear pinion completely tore through the bulkhead. Both gears were fine when I took it apart.

I got the bulkhead replaced and figured the damage was a fluke. Last Saturday, It was holding up great. I was driving fairly recklessly doing backflips off of jumps and had some bad landings that would've broke the stock pinion right away. At the end of the day, I did a standing backflip off a curb and heard something crack. After it landed, I heard the click from the rear diff. I'm pretty sure the pinion lost a tooth. I saw exactly what happened though. When I did the backflip, I saw the rear wheels hit the curb and that's when I heard the crack. I haven't torn it apart it to see the damage, but chances are the pinion broke a tooth.

Everytime I broke a stock one, It was from doing a backflip and landed hard. I always let off the throttle when i'm doing the backflips, but maybe i'm not letting off early enough.

The CEN gears seem to be significantly stronger, but not quite "bullet proof" yet. Then again, I am driving it harder than I probably should.

Hopefully HPI's new diff will be much better.

A good example of why warranties have small print!!!!

Glad you are having fun with it!

This thread is a bit old, but you asked me a question and I don't think anyone else answered it. I am using the NITRO savage pinion gear, with the stock flux bevel gear. I added a shim to the pinion, and it works awesome for me. Like I have said, I have done probably hundreds of backflips now (it entertains buddies lol) and since I changed a few things, no broken diffs.
