Have you guys experimented with caliper steering yet? I have been trying to figure out how I could mount the bearings to the caliper... Nestor recommended to drill 3 holes in the caliper: 2 for "bearing mount quad block" mounting holes (what a mouthful), and 1 for the axle to go through. Not sure how I would drill through a metal caliper though...

Ideas people? windu I think you worked with calipers for your 2017 electric vehicle, maybe you could clear things up for me?

The two wheel bases are connected with threaded rod. When you turn the threaded rod (make it tighter or looser) it changes the gap on a side. This changes how parallel the two wheel bases are. https://docs.google.com/drawings/d/1XKU4HsWKpytWDIck0PxirKUHHjJyCxKBACvlO0IHUbg/edit?usp=sharing

I would recommend against threaded rods - they are heavy. It was fine for electric vehicle because we had plenty of motor power, but with battery buggy, you do not. I used 3D printed parts and epoxy to for my caliper steering system. I have pictures on the Best of 2017 page. Additionally, if you want to email me, I can send you additional resources.

Ok thanks now I know how it works!!! So basically your frame is partially threaded rod as well... did you take this approach?

Yeah I thought the same thing. At least 10% of my vehicle's weight comes from the threaded axles alone. If I were to have more threaded rod in my frame... *shudder*... I would have one really heavy vehicle... :P
I will definitely look at the best of 2017 page... and I would appreciate the additional resources :) ! Should I PM my email to you then?

As an unrelated side note, can I upload pictures of my buggy and my tower to the Best of 2018 page even though they weren't the best?

I think as long as you were top 10 at nats, you can post? Idk I don't make those rules haha. Yes please email me, not PM. That goes for anyone who wants resources on steering - I cant add attachments through PM.

I did not take this exact approach. I might share in best of 2018 and you will see there.
