05/31/2001 11:40:03 AMTom,At the risk of sounding repetitive, buy the plans, buy ALL the plans, theyare going to be a minor part of your total expense in building this plane!A few years ago, Don Pietenpol compiled all the Flying & Glider Manualarticles into a 'Construction Handbook' that he sells as part of the planspackage. In it he states that he did some editing to CORRECT MISTAKES andOMMISSIONS. Also, I believe that there have been several corrections tothe actual plans themselves since the F & G Manuals were published (I don'thave them in front of me, but I think all of my copies have a note on themthat says something like 'Corrected 1967, DPP'). Also, hook up with allthose guys in Mpls. I've learned in my short time as part of the homebuiltaviation community that people are almost itching to help out others.On the subject of weight, I'm not the expert, being a midget myself, butI'll throw this out to stimulate conversation. You may want to consider amore powerful engine. William Wynne says his Corvair conversion develops100hp tops & 90 hp continuous (cruise). He also has an option for usinglarger VW pistons and he says the numbers go to 125/110hp. Otherpossibilities might include going to one of the larger Lycomings (Mike Cuy& I were trading jokes about using an O-290 just yesterday - that'sprobably too big, but maybe an O-235?). One other possiblity might beanother auto conversion, like a Subaru. From what I've heard, Stratus doesthe best job on the EA-81 conversion (100hp). There's also an outfit in theCanadian northwest that does Honda conversions (www.firewall.ca), but theyseem to be revamping their web page & there's currently no information onit.That's my 2 cents' worth!Kip Gardner Dept. of Ocean, Earth & Atmos.
