concerning the inner axles can we just cut the end off other axles and put flat spots on them to fit? Is that bearing race the same as on it SCX10 II spindle?
No, as the large inner knuckle bearing is 1mm closer in the portal.
This might have already been commented on, but can't find it via the search function.
Has a complete front portal set up being released yet, or can we now use the front set up on a Pro44/Diamond axle?
I am sorely tempted by these portals for my UMG10 build, but a little confused on the front end over what to use for a strong set up.
All the Portal knuckles have been updated to larger CVDs.
The rear portal axle has been updated with stronger nylon parts now.
We will also be releasing new aluminum rear tubes and rear portal housings next week. Portal weights will follow shortly.
We dont recommend using portals on the original Axial plastic axle with tiny splines as the portals will strip the splines and spin on those.
This is why we only recommend using the front portals on the newew Axial one piece plastic axle. As the C hubs are fixed.
We will release a new nylon front portal axle soon with aluminum C hubs, same fitting as our Trail King front axle (not tiny splines).
