Vorteks Driveshaft bearing necessary?

[vortekyteky]

Hi all,

I have just 3d printed a driveshaft cover for my SWB arrma vorteks. The cover does not fit the nicest with the plastic mount for the bearing.

The truck is running on 4s, capable up to 75mph+, do you think the driveshaft can hold itself together at this speed?

Thanks

Wow! 4S, 75mph.... I would be keeping that bearing.

ok thanks

Without that support bearing... I wouldn't chance going That fast.
The vibrations coming from the center driveshaft at those speeds would likely destroy the input bearings (in the diffs) after a couple of packs.

This post reminded me of the below video. Check the slow-mo footage in this timestamp to see what the plastic driveshaft looks like on 4S without the high-speed support bearing.

Try notching out your cover just enough to accommodate the mount, but not enough to let any thing get in.

Or make it in two parts -front & aft sections of the support bearing.

Rotating plastic at 40000 rpm will do wonders to its form, not good for driving though.

YES!

Do you really do 75 on gravel roads? That is, do you really need the cover and the bearing at the same time?

Probably not actual speed of 75 on gravel, wheel speed will occasionally reach that though. I might get up to 55 on the gps have not tried it

I have edited the 3d printing model so it fits around the bearing
