YouTube- The HOY! Pinoy Mini Car Space Frame rustproofing

In the video you displayed the bare chassis without the engine & body.

I noticed all the squared joints. I also noticed the chassis looks like it has too much material in many places which are redundant. Fine for prototype but not good for "finished" unit, especially the squared joints without any diagonals/triangles will be weak & requires more material just for stiffening purposes. This is much like the Micro-Car 1 done in DLSU years ago by a designed & assembled by a different engineering team.

In this video, the basic drive system is more clear. Did you include a chain tensioner on the chain drive from the "axel" to the rear wheels? Vertical movement of the rear suspension (leaf spring) will result in chain slack which may result in the chain jumping off the sprockets. This also happened in DLSU's Micro Car 1 (although this had trailing arm type rear suspension to avoid/minimize chain slack during it's suspension travel arc).

That "bare chassis" WAS a prototype chassis ver 0.5. Definitely not for finished units. Everything you see in today's prototype ver1.5 are "dry fitted" to see what works or not. It's built as weak as possible so it CAN BREAK NOW, then i can fix it now so i can consolidate all the fixes into a "new" chassis version.

The square joints are meant to be reference points for squaring everything that follows. They are "educated" guesses which road testing will prove good or bad. I am not good with 2D drawings, i need 3D joints that i can "feel" and move around an inch at a time.

If you have worked on airplanes, you would really be amazed to see how they "fit" all that stuff "in there" and still fly.

Until i can fit "all that stuff" where i want to, the HOY! is not gonna fly.
