Ramp Update:
After I got comfortable with hitting the ramp at higher speeds, the coroplast and the 1/4" plywood wasn't able to hold up in the curved section of the ramp.
At 3s speeds, the truck would sometimes bottom out at the trailing edge and this was tearing into and ripping out sections of coroplast. One of the 5 curved joists also broke from the impact at higher speeds.
So I had some 1/4" and 1/2" Acrylic scraps that were gifted to me and decided to try re-making the curved section out of Plexi. This build brought back memories of Jim Henson's' Fraggle Rock and the Doozer constructions and rc cars they would drive around on clear acrylic models! If ya don't know what I'm talking about, you should definitely check out some old videos of it online.
I kept the lower half of the ramp as is with coroplast and plywood since it has been holding up ok so far. The overall weight doubled (now ~10lbs), but so did the strength and durability. The surface is a .06" thick sheet of PET and is attached to the frame with VHB double sided clear tape.
I've hit it pretty hard a few times now and it's Holding up very well. The surface is getting scraped up, but that's fine with me, I'm expecting that it will not be so transparent after some spirited bashing.
