Granite After a year of waiting i finally got these, the CVD driveshafts.

[MeesterC]

I have been waiting on these for so long that I had forgotten that I even ordered these. My initial order for these was in February of 2019 a d from there they kept going on backorder, I finally gave up a d had forgotten about them until a package showed up at my door a couple of days ago. These are the CVD driveshafts that arrma has come out with for the granite blx. First impression was that they look good while they're in the package.....lol. After I took them out and really got to looking at them I wasn't all that impressed especially at $35 a pair. The metal pivot ends are molded into the composite sliders about 3/8 of an inch, the pivot eyelets are thin, the pin retainers on both ends are plastic and the sliders look thinner walled than the stock sliders. I did however switch sliders around, i put the cup slider to the inside and the inner slider on the outside, this keeps dirt and debris from getting inside and causing binding, learned this trick from my crawler rigs. With the cup slider facing down the dirt doesn't collect inside. Anyways back to these CVD's, I was expecting a little more durable looking shafts for the money that was spent. Not really sure as to how well these will hold up over time. I'm running the hobbywing ezrun max10 sct brushless combo with the 3200kv motor on 2s and 3s and yes I play hard with it. The eyelets on the ends look really thin, almost like they will snap or break easily, the end that attatches to the differentials is also plastic and held on with a grub screw. I don't know, to me these just feel cheap for the money. I'm pretty sure that in time either the picot end will break or pop out of the composite case but only time will tell. I have attatched plenty of pictures for all to see and you can also see how I flipped the sliders around. Let me know what you guys and gals think. Does anyone else have these? I'm running these on front and rear.
A few more pictures.

Well hopefully they hold up better than the stock ones did.

Hopefully the plastic they used for the outputs are differant in my kraton 4s they all are rly sloppy i think it doesn't matter but heh for the price you pay you should not have that kind of play
How do you keep the dirt out from the sliders?

 

[tdikyle]

Have you taken the truck out with them fitted yet? Interested to see how they cope with people over tightening slippers and upping the punch.

At least you can buy parts for them if they break rather than buying the whole thing.

To keep the dirt out of the sliders I switched them around. I put the female slider on the differential side and the male slider on the axle side. Now the female slider points downward allowing any dirt or debris to fall out, this keeps them from getting contaminated and cause binding. Learned this from my crawler rigs

Yeah, I've taken it out and played with it. I guess I should have mentioned that I have my slipper set at a quarter of a turn loose from all the way snugged down. I think my punch is set at 5 because before I received these new CVD's I didn't want to break the stock axles. I'm gonna turn up the punch and see how it does.... I'm really hoping these will handle the abuse better than the stock shafts.

Keep us updates please. I have seen them on the website and almost ordered some, but I'll watch this space first. Time will tell if they hold up.

Punch only goes up to 5 on the granite, it's set to 3 from factory

He said hes running the EZrun ESC. I believe that goes up to punch 9.

AHH missed that bit, skimmed through on mobile.

 

[Surchaufeur]

Idk whats the slipper tune for the 3s slipper i only k ow the 4s ones are 1.25 turn

 

[razorrc]

Set your slipper by how it performs, not by number of turns. It just needs to slip for a split second when you go full throttle from a standstill on the street.

 

[MeesterC]

I'm going to turn up the punch and run it on 3s to see how they hold up. I'm only running the punch at 5 and on 2s right now with a 15t Robinson racing pinion. Weather here in good old Georgia isn't cooperating, rain and thunderstorms for the next couple of days.

 

[Branson_Basher]

MeesterC, thank you for being an early tester of these cvds. I'm one of the many people who are on the fence on ordering these parts so your experience is invaluable.

 

[MeesterC]

Okay, I finally had some time to tinker with granite today. Haven't had a chance to run it again yet because of rain. I did however adjust some of the esc settings and my punch was already maxed out at 5 but like I said before I mostly run it on 2s, helps with repair costs.....lol. I do have a few 3s that I'm going to run it as soon as the weather clears up. It's now ready to run, just waiting on the rain to go away.

 

[Branson_Basher]

I hardly run my cars this time of year so I totally understand; between the rain, the low temps, bashing spots being a muddy mess and how cars seem to break a lot more I usually spend winter months on other hobbies.

No rush

 

[MeesterC]

Well, ran the granite today on 3s and so far the CVD's are holding up pretty well. I did abuse them some to see if they'd handle it and they did. Truck will almost do a standing backflip on 3s so I tried to accomplish a complete one several times, like around 20 or so times, and they held up well. Along with some speed runs, high speed turns, bashing in grass, gravel, dirt and some mud they were quite and durable. Only time will tell on these and will keep updating, but for now I'm impressed.

 

[slick2500]

God I'm smart, I didn't want to buy these for my 3s Typhon because the stub axles are different, then I remembered I am running Granite stub axles anyway.............

 

[Branson_Basher]

Thank you for the update and your willingness to risk breaking your new rc parts like that.

There may be hope for my BRCC yet.

 

[MeesterC]

Well, I've been running the dog crap out of my granite on 2s and 3s, speed runs, jumping, mud, water, gravel, rocks, sand, grass, thru woods, creeks and everything in between. These axles seem to be holding up pretty well but my main concern is the pins and the pivot points, wondering if the holes will woller out over time. I'll keep beating on this little bad boy for a while, then remove the axles and check the pins and holes in the shaft they pass thru. Over all they do seem to be a lot better than I expected or gave them credit for, way better than the stock plastic ones. Will keep updating this thread as time goes on.

Good to hear. Thanks for keeping us updated. ?
