Looks good Fred !
Although styrene is somewhat easy to detail, for a regular driving car, it won't last in terms of structural integrity... So I may copy some of your patterns and the try to encase them in styrene! But that will not be anytime soon lol !

I also picked up a set of the SDI axles last year for an FJ40 build that I want to do, but haven't even had time to open the packaging as yet ! So looking forward to seeing some details of you shortening and lining up the axle!
I really like how the axles are narrow. It's a pity that its not a proper open diff. I wonder if we could find a diff small enough to fit in there?

Before actually seeing the axles I thought there must be some ball diff to fit in there, but pics of SDI axles are deceiving, they are much smaller than they look, here is the spool next to a few items (the sandard tamiya nut wrench and the cc01 axle, plus my mini sized tire and wheel):





I do not know enough different kind of rc cars to know what diff would fit, but that is so small I have a hard time believing something can fit in there and have some strenght. Maybe diffs from mini trucks or something? Like 1/18th? The spool core is almost the same diameter as the larger end of the tamiya nut wrench.

Nope! Hahaha I prefer that, no cuts and also I did not like the idea of shortening only one side and end up with a non centered diff.. And the holes all along the axle are just right for my four links location

In case anyone wants to look in his parts bin for a diff that might fit here are the dimensions of the spool:

Crown gear outside diameter: 0.900"

Diameter of the core (the middle part): 0.420"

Diameter of the bearing seats: 0.234"

Width overall: 0.855"

Width on bearings shoulders: 0.620"


If anybody finds a diff that might fit let me know which dimensions are missing and we could compare a little bit more!

Yeah..sweet! I have also been toying with the idea of using a different diff (if I could find one) complete with the case and using the axles and axle casings from the SDIs to create an axle with an unlocked diff...if that makes sense! Lol!

Like for instance, the RS4 diffs use out drives that use dogbones as axles, what if we could somehow attach the SDI axles to this diff ? I know that the RS4 is a bad example as it's not completely round like a diff is supposed to be, so would not look correct, but it is centered. Maybe some other vehicle has a diff that's more appropriate? I too am not familiar with many varied brands, so not sure what's out there....

This one you linked does look much better than the CC01 axle, I think because the axles are thinner (and also the nice detailing). I do not think you could mix SDI components with others especially the actual axle housings because they are so much smaller than anything else. You would probably be better starting with an axle that has a diff and hack it to add tubes on both sides and retain only the center portion and the two ends. I think the challenge would be to mate the diff housing area with the custom tubes while keeping it strong...

what about MRC axles? theyre much smaller, and i believe they can have open differential fitted to the center.

I will make sure to get enough steering angle and a quick servo to hopefully have a chance to get out of trouble when the rear suddenly snaps in overseer The lower arm design should make that possible I think (not a wide A-arm+knuckle but instead a single arm with ball joint holding the bottom of the strut)

I plan to do the steering rack in front of the wheels like the actual escort too. Not sure how yet but it probably wont be RC standard I am thinking of a sliding rod inside a tube, with small joints and rubber boots to mimic an actual steering rack.

Look how small the four links axle brackets are going to be, this is the cardboard model and I will use the same steel (22 gage) for this. See how small it is compared to the similar bracket on the cc01 axle:





Edit: that is 0.8" distance between upper and lower links instead of 1.2"
