These are the fascinating types of toy model plans that would show up in magazines like popular science. I used to Xerox and collect them, when I was a kid. Now some of these I have found on the internet scanned to pdf. -Kwok

Model Hydroplane (really a hydrofoil)
cyberhoops @ rcgroups actually built one of these and has posted videos of it running: http://www.rcgroups.com/forums/showthread.php?t=904885






Hydrofoil Sailboat
Actually, I wouldn't attempt making it sail powered until you try it with a motor. Electric air prop being the easiest for proof of concept. I could not find any pdf plans of this one, like the others. These are scans from my Xerox copies. Even though they are jpg, I will post them here for completeness.
