High gear ratio in the axles??

[metblack328i]

I am sure this has been discussed many times before but I cannot find a firm answer anywhere. The stock Ascender axle ratio of 1.85 is pretty low and toque twist is pretty crazy on the WB1. Does anyone know if vaterra plans to sell higher ratio gears? May be reduced teeth on the pinion?

I think you have it backwards; low gears prevent torque twist, and "high" or "tall" gears increase torque twist. This is how I understand it. So you would want to gear the axle ratios down to help calm the effects of torque twist as well as suspension adjustments and weight placement. It's always gonna have TT but there are ways of hiding the effects of it.

I meant higher "gear ratio" which is achieved using low count pinion gear for a given ring gear.

I don't know if Vaterra is going to release an OD or UD gearset, but it would be nice.

A rear swaybar, Double-DZS-RC RULRs, your home made rear upper link setup, or rear leaf spring conversion (home-made or bought) will greatly reduce the TT to a manageable amount. "thumbsup"

Yes. "thumbsup"

I would also like to see if retrofitting a scx10 ii axles on the ascender would help. With proper spur and pinion gearing ofcourse.

I would also like to add moving the lower shock mounting point out on the axle.

As Nate said, a little tuning will go a long way. No point in waiting around for a gear set that may never come when all the information on Ascender suspension tuning is available right now. My Bronco (which is on a slightly shortened WB1 chassis) torque twists about as much as my SCXII at this point.

Forgot to mention out-boarding lower shock mounts like I've done on both mine, thanks Svt923 for chiming in! Yes, read through build threads the good tuning info is here. 8)

Where can one buy said Double-DZS-RC RULRs? Google was no help there

This helped on mine a bit. I'll post picks when I'm back home.

FWIW, I bought the following off of amazon to make the out-boarded shocks mod:

Spacer kit to match (awesome kit to have on this truck, as it'll let you experiment with various setups down the line)

Sway bars are band aids. The truck is flawed with its axle gear ratios. I'm surprised it sold as somewhat seemingly well as it did.

I'll take the torque twist and "band aids" over the big gommy knuckle dragging scx-10 axles. They sold so well because people with th axials saw how daily stock ascenders were keeping up with their high dollar modded scx's. I know because I was the first in my group to have an ascender and now 3 others do.

Aren't you supposed to prevent flaming wars as a mod? Just sayin'...

Go back in your hole troll

 

[EeePee]

I laughed because you're grudge against me is so obvious it well, makes me laugh. You trolling me? Sure seems like it.

I can speak my mind whether I'm a mod or not.

Years and years of experience with fairly proper set up trucks have proven to me sway bars are wrong. Do you know what sway bars really do? Then there's the axle gears…

Maybe you should look into the anti squat and suspension etc thread we have here? Actually, there's two. Duuuuuuuude's and the better one that came before it.

 

[Itali83]

I didn't deny it was a band aid. I would never put a sway bar on a 1:1 truck. I said I'd rather take that one flaw over the others that the other brands have. I'm not trolling, wouldn't dare try to BS the master BS artist. Mama taught me better than that. But when you come to a brand specific section, and talk blatant sh!t, gotta expect a call out.

I feel better. Troll on brotha

I'm in almost every section of this forum. I have 13 trucks dating back to 2003. :shock:

In this case, no Ascender cause I know better than to have those axles. But proper suspension is just that.

You calling me a troll and the master BS artist did not go over well. It'd be a bummer if you couldn't visit RCC any more wouldn't it?

How's that for being a mod?

 

[Itali83]

Oh yeah, here comes the big dick swingin'. Pretty sad if you ban me over one incident but do what you gotta do bro. I'll be a good boy from now on I promise. W8)

Where was the smack talk? He made a valid point without calling anyone names.. something that failed you.

I wanted to like the Ascender, but the ratios and floppy suspension killed it for me. A decade old axial axle is hardly a fair comparison.. Vaterra had that long to make it better and missed the mark a bit. There is no shame in admitting that.

 

[pete959]

Out the box truck for truck ascender is far superior no need to up grade links or buy hd trannies or drive shafts. Plop u a 3 s in the tray flip a switch and out do upgraded scx all day the only reason i want an over under set is to be able to run with pro comp trucks we have here in the south.

Well Eee Pee, normally I kind of like your dry humor. I think your assessment of the ascender axle gearing may be correct and we are still working on tuning options to work past this, as is the SCX10ii and its new tranny problems. Raising the rear upper links is helping way more than the sway bar fix. I think that we are as loyal to the ascender on this site as axial guys are on their site. We don't have the near the after market support as the axial crawlers do. So we work with what we have and I will put my ascender K10 with the upgrades we have up against a scx10ii any day and crawl right with it. Have you taken the time to drive one? Also I think you may have over reacted in your threat to Ben, as he was just answering your negative input about a pretty good and fun to drive crawler. I know it probably doesn't make any difference to you what I think, but your reaction disappointed me. "thumbsup"

X2 Well stated Ernie, thanks.

Every rc has it's pros and cons, both my Ascenders work very well and I enjoy playing with our toy trucks and helping others get the most out of them.

Now I dont go too far from this page, and have not heard about the axle ratio issue. How far off is it, and is the truck geared too fast, or too slow?

When you say "floppy" about the suspension, what makes it floppy, and what parts need improved? The ones everyone here is working on already?

My bud got an axial when I got my blazer. The vaterra has been more durable, and has performed better in our travels. It also included some parts that were expensive upgrades for my friend also.

My swaybar may very well be a bandaid... But it has really made my truck outperform the axial, which has about 2x the money put into it.

Funny how it's always polite and kind worded comments in here till a mod pops his head in. Maybe he thought he was still on Facebook? :lmao:
Anyway... I crawl in a sea of SCX10II's with my stumpy Ascender Bronco and have yet to have an Axial crawler do anything my Ascender can't do. I look at it like this. Vaterra built a good enough crawler that Axial built somewhat of a similar rig, so it can't be all that bad. Except the Ascender truly has an adjustable wheel base, decent shocks, tranny that's way better and still has more steering. So what if it takes 15 minutes worth of modifying to fix the torque twist. Takes way more time and money to get the new Axial rig to roll with the Ascender. Several of the local die hard Axial guy's are turning to the dark side and trading in their beloved SCX10II's for Ascenders. Funny how something can be the best of the best because nobody has taken the time to try something different, then someone shows up with that something different and leaves them all wondering what just happened.
