I don't think it's an issue with the body shells from what I can see. It may be just a minor mistake on the 44B chassis instruction manual
(as I said in the Bearcat SS thread, I'm not sure the guy who wrote the manual and draw it actually built the car )

I got a city bumper delivered today. It was not very long to model. https://i.imgur.com/Ebc24jn.jpg https://i.imgur.com/04yOMaw.jpg I also have the City roll bar https://i.imgur.com/04yOMaw.jpg https://i.imgur.com/GL39sIq.jpg Then I derived a Vega Bumper from what I could see from the pictures I fou...

It looks ok, but Im' not sure of the measurements yet, as there is a lot which are derived from the geometry and from what I have seen on the 44B parts rather than actual measurements... Proportion looks good, but I'll need to go for a print to confirm it is ok.

After a night to sleep on it, I decided to pursue. The approach for each pipe : Set a 3D sketch for each pipe, with the ends of the pipe being different segment, with the idea of using the same sketch for the big and small diameter pipes (this one needs to be smaller, as there will be a fillet appli...

I wondered if it was moulded or hot pressed out of sheet. Reliant on the upper belt cover for some stiffness. On one zerda I have some metal angle reinforcers on the castor angle. I don't think they're in the manual. May have been an afterthought accessory or third party mod. Looking at the fixatio...

Fully agree...
It would be so simple to have with each pinion, gears or other technical part a single description with the différent elements making it easy to find equivalence...

(and the same goes for tires and rims...)

That's bad luck with the chassis , sometimes there's just no fixing things and with Fusion you often don't know why you can't fix it ? :| Glad you get it done in the end , it's looking good :!: One day your going to have to computer animate a race between all your CAD model cars :lol: I saved the f...

There was few parts remaining to deal with, and in particular the C-Hub... I decomposed it in few parts I modeled and then assembled the bodies... https://i.imgur.com/PNz0ERG.jpg https://i.imgur.com/4HdNyKz.jpg https://i.imgur.com/pOrOwJj.jpg https://i.imgur.com/LCCoXqE.jpg After the assembly and bo...

Again the hub carrier is fairly complicated , doesn't look to bad at first until you really study it , I remember several attempts to get the cut out for the knuckle steering arm right . It's fairly complicated, yes, but once decomposed it i's fearly logical and easy (seems my brain is wired to wor...

thanks to threesheds , I have now some nice shocks for my Zerda :-) https://i.imgur.com/gESCvs0.jpg I put them on the car next. Apparently, It really needs a pivot ball... and Fusion 360 doesn't like my joints (I did a shortcut and did not put screws in, and apparently, it would need again something...

Well... Lot of part very difficult to finds among those broken if you are searching for originals... I would start by tear it down to parts, and check the state of all metal parts and transmission parts. If everything is in proper state, there is easy printed 3D part from Dadio on shapeways and from...

Well, 2 out of 3 diffs are basically destroyed. The rear diff has 2 trashed spider gears and the center diff is poorly epoxied together. also that transmission half with the epoxy is cracked in several places. I guess if I come across replacement diff gears at some point I'll rebuild this thing wit...

Test 2 Front Gearbox for 44B https://i.imgur.com/vjeN9hl.jpg Again everything lines up perfectly. It's good feeling when everything matches. Test passed. Test 3 Front Gearbox for Zerda https://i.imgur.com/wcSC92z.jpg The front profile doesn't match exactly. I will have to find out the exact differen...

As mentioned by Silvertripple Shapeways has the gearbox for sale and I've bought one and can verify it's good probably better than the original , gears again as Silvertripple says the Hitec Aristocraft Dolphin or Kangaroo gears are a drop in fit , the front bulkhead/body mount can be found new on e...

Beside my own testing, I sent my stl files for the 44B-SWB to a friend who had a chassis without bath tub. He had quite hard time to invent one, and succeeded, but when I proposed him to do some test of my bath tub, he welcomed the idea... Yesterday evening, he sent me some pictures... https://i.img...
