I'd LOVE to have one of THESE!
The kids wouldnt be touching THAT !!
These guys have PVC-framed peddle cars http://www.americanspeedster.com/
, but thier wheel/suspention setup is totally unsuited to the terrain around here (farm fields, ATV trails and gravel roads). It would be easy enough to adapt a 5hp motor to thier car but it still leaves the running gear issue.
When I said PVC with aluminum, I'm thinging more in terms of the tube/gusset method used in ultralight airframes, The main frame would be aluminum tube inside the PVC tube, with the PVC more or less acting as a "coating" and an assembly aide, and a secondary structual tie-in, Once the frame was assembled and glued, gussets of 1/4" aluminum would be bolted to the sides of all joints. very light and VERY strong, for the main part of the chasis anyway. The superstructure would be just plain PVC (or ABS) to save weight and cost......AND, I just happen to have about 20 pieces or so of 7 foot by 2"/.063 wall 6061-T6 tubing laying around as cut-offs from wing spars on my past projects
.........All stuff the kids can cut with nothing more than a hacksaw and a cordless drill.
