It has been explained before, that having this "extra meat" you speak of on the CV (or dogbone), only weakens the part. This being because you still have to turn the end down that goes into the drive cup, so it can operate at the required angles. This leaves you with a shaft that is thicker in the middle than on the end...therefore, the end becomes the weak point. When the CV (or dogbone) takes an impact, the area that's the thinnest (in this case, the end that goes into the drive cup) will take most all of the load, since you've made the rest of the shaft bigger, so all the load is transfered to the weakest point...making it fail easier than if the whole shaft was one consistant thickness (this way it could transfer the load from the impact over the whole length of the shaft).

Robin has engineered his parts to actually take the beating, not just look like they can. And its been proven over several years of hard use and abuse by many veteran UE users. If you switch to using UE CV's, I'm certain you won't have any more issues like what you've had with the MIP shafts. No change is needed to his design, to make them stronger.

Alrighty then

Do these bend or break? I just want to prevent bending them, don't think I would have any issues breaking them. This "extra meat" sounds like it would add torsional rigidity as long as it was machined smooth with no hard edges.

Its exciting news that Robin is running more CV's...these things are kind of hard to come by these days, and they're almost always used, if you do find some.

If you can wait, and don't need anything right now, I'd advise you to get some of his when they become available. You won't be disappointed!

I have bent a pair of UE cvds... A long time ago. It was on an Ofna Monster Pirate with the proline conversion bulks and a RB TM728.

No question I want a set! Robin, ygpm.

Like I mentioned, if you get the drive cup depth wrong and it comes out all hell breaks loose.

That or in a crash. CVs aren't meant to take that kind of load.

That's about the only two ways I know of to bend a CV like was shown above.

The ones in the picture above were too short and popped out. The ones off of my dominator had a small bow at the end of their life. Time will tell. I am certain they will outclass the MIPs

Could part of the problem here be that the setback arms and the MIP's are not a good combination?

From what I understand, the MIP's are a smidge shorter than the UE's? And when I set up my Racer X suspension for the first time, I noticed that the setback arms definitely require the pillow balls to be set as far in as possible to get good depth on the CV and drive cup...and that's with using UE CV's! So if I've got it right here, given that the MIP's are a bit shorter, they would definitely have a good chance of popping out when used with the setback arms. No?

Just a thought.

Not sure if they work but traxxas used to sell extended CVD cups for their setback arms on the revo.

Here you go

I have exhausted my options for now, I'll wait for the new batch:intello:

Did you get my pm MonsterMaxx?

I need to know if I need to order new bearings or hubs or if you will be able to machine a set for me? Can you give us something besides near future? I'm not going to chisel it in stone, I am just curious. My truck will be down until then. I straightened out the MIP shaft once and it didn't last 5 minutes before it popped out of the cup again.

Oh well, nature of building a custom beast :diablo:
