The plane balances on 2 round head machine bolts. Very gentle on foam wings. I have a list of materials and dimensions and prices from a local Lowes around here somewhere if anyone is interested. I love working with pvc tubing and you may have seen my Thrust Machine I built out of PVC in an earlier post. I also used the 2 dowels in the 2x4 but the darn thing kept falling over and then went "high tech"
