wraith axles, torque twist, and pumkin side.

[STANG KILLA SS]

first of all I need to explain, last month I joined the 21st century and finally bought a set of wraith axles for the first time.... im completely clueless about them

i have a question. stock wraith axles appear to have both front and rear pumpkins on the drivers side.

how does this affect torque twist? what im getting at, would flipping them both to the pass. side make torque twist better or worse? ( this also reverses wheel rotation)
upper link mounts will be custom so that's not an issue.

and further more. how does flipping over the ring gear affect all this? ( Team RCCrawler Tech Tip: Do I really need a reverse rotation motor in my Wraith? )does this theortically affect torque twist as well?

which combo of these two would ultimately be the best? (pumkin side and ring gear side)

thanks!
Cory

Sorry I can't help re the torque twist but I'm currently working on building my first set of wraith axles, well I'm gathering parts ATM, but from what I can see the housing's are reversible, meaning you can run them either way by flipping them and swapping the ring gear/ centre around, I hope this makes sense. And I will be interested in the answer RE TT.

You can't get rid of it. I flipped the gears and it still lifts up on one side. It could be lessened by different shock oil weights and pistons.

^^^ hate to tell anybody tryin to get rid of torque twist it ain't gonna happen you can maybe lessen it but you'll never get rid of it. We've been fighting it for years in drag cars you can lessen it but its still there. Which ever side you twist to add preload to the springs on that side or run a heavier spring.

hmm I think im being misunderstood.
im not trying to remove torque twist. just minimizing it a little.
the pumpkin changing sides would obviously have a difference on leverage. ie like using a short wrench or a long wrench.
thus if I can flip the pumpkin to the side that has the least amount of leverage, I could in theory reduce TT a hair.
at least that's how im picturing it in my head.

Seems tires always turn the same direction and you may be chasing a twist dream

[allanon1965]

the leverage wont change, thats coming from the driveshaft twisting the pinion...

[STANG KILLA SS]

gotcha good points. but the driveshaft and pinion rotation can be reversed according to the link above, maybe that's what I need to focus on?

Me and JeremyH are running opposing rear axles and it has reduced torque twist significantly!

I am running 13/43 HD axial gears in the diffs and a 27T holmes motor with the supershafty trans gears upgrades and I have virtually no torque twist, the only thing I did different was increasing the preload on the rr spring/shock...but even before that it was very minimal...

that being said, the taller the gears in the diffs, the worse the torque twist will be....tall being high speed and short being slow speed...

Jeremy has some detail about it in his build thread.

Here is a photo of mine.

funny you bring up Jeremy. ive talked with him in PM about his flipped axle.
need to read up on his thread.

that's gonna add another variable to my confusion, flipping only one axle...

So you just flip the axle, and run the diff on the opposite side and you're good to go?

Flip the rear over and you have to flip the ring gear also, so that it runs in the proper direction.
IIRC you will need a front upper link mount to go on top of the axle.

Hey STANG KILLA

If you run the axles both driver side drop and run the ring gears opposite of how it shows in the manual the torque twist goes away for the most part. That's how the RTR wraiths come from the factory. But remember that running the diffs that way require a reverse rotation motor.

With the ring gears installed how the manual shows, The truck will torque twist so bad it will three wheel up steep climbs.

with big power if the diffs are installed per the manual, just punching the throttle on flat ground will cause the whole chassis to lean right and pick the front left tire up.

I haven't noticed any difference between these two -

[evan03]

those are some baddass rigs . would like to see some more photos of them

[The Doc]

I run a hot body's sway bar in the rear and sand it down till I get it where I want it. I do still have a little tork twist though

I am going to try this. We have a decent hill climb and when i start to bite hard it 3 wheels a bit.

Good thread thanks!
