4wd SRB Trailing arm buggy

Post by AscotConversion »

In admiration of 1300GT's 4wd SRB, I'm starting on my own attempt at building a similar car. I figured out a B4 slipper gearbox setup in this thread - https://www.rc10talk.com/viewtopic.php?f=32&t=44855

Now I'm mocking things up for the chassis. 2 3D printed replica MIP gearboxes, 3D Printed front arms, Optima front hubs, Scorpion trailing arms.

Could you share the files for the 3D printed stuff?

I got the chassis cut out and suspension mounted. I'll have to make a roll hoop to mount the shocks in the rear. The motor is going to hang off the back Scorpion style.

I think the 3d parts will get dyed too, they get dirty if you handle them too much when you're mocking things up.

I'm workin on it! :mrgreen:

Just got some more aluminum tube to finish the cage. Unfortunately, remodeling my kitchen keeps getting in the way.

I also ground down the Optima front knuckles, as they are taller than SRB knuckles, and take away a little front end travel in stock form.
