Very nice design. Looks like an afternoon project for 1 or 2 people. The chain tensioning set up I have used for many projects and while it does looks crude it works great. GRT has used eye bolts many times. I would add a cross brace at the top but that is my preference. This design would give a team a cheap practice chassis and one to test mechanisms on and save the kit chassis for later if they wanted to. Good work.
