Issue #109 MISSION CONTACT! Magazine is published quarterly by Aeronautics Education Enterprises (AEE), established in 1990 as a nonprofit corporation, to promote aeronautical education. CONTACT! promotes the experimental development, expansion and exchange of aeronautical concepts, information, and experience. In this corporate age of task specialization many individuals have chosen to seek fresh, unencumbered avenues in the pursuit of improvements in aircraft and powerplants. In so doing, they have revitalized the progress of aeronautical design, particularly in the general aviation area. Flight efficiency improvements, in terms of operating costs as well as airframe drag, have come from these efforts. We fully expect that such individual efforts will continue and that they will provide additional incentives for the advancement of aeronautics. EDITORIAL POLICY CONTACT! pages are open to the publication of these individual efforts. Views expressed are exclusively those of the individual authors. Experimenters are encouraged to submit articles and photos of their work. Materials submitted to CONTACT! are welcomed and will become the property of AEE/CONTACT! unless other arrangements are made. Every effort will be made to balance articles reporting on commercial developments. Commercial advertising is not accepted. All rights with respect to reproduction, are reserved.

2015 CALENDER OF EVENTS As of this writing, I’m not exactly sure which events we’ll be attending this year except for EAA AirVenture Oshkosh and our own Alternative Engine Round-up, which you can read all about on the back cover. I’m also slated to present an alternative engine educational forum at EAA Chapter 723’s regular meeting (Camarillo California) before the end of the year, but the date’s not set in stone yet. We presented there a few years ago and it was well received. This year the Golden West Fly-in has been moved to October 17th (it’s usually in May) which is the weekend before COPPERSTATE, where we’re usually a fixture except for last year when we had a conflict and just couldn’t make it.

We attended Sun ‘n Fun earlier this year, and as in the previous three years, we simply hung out in the forums classroom we’ve been assigned, and that seems to work okay. It seems that people still haven't gotten used to finding the forums in the beautiful air conditioned building yet, as this year’s numbers were way down in the forums building. In one case, we only had three people attending a forum that should have been standing room only. Continued on page 23

3 Pete Plumb’s Pegasus DP-1 O-100 Prototype.— CONTACT! Magazine’s editor, Patrick Panzera had the pleasure of meeting Pete Plumb at EAA AirVenture 2012 and has followed his progress creating his O-100, a half O-200 that uses O-200 parts. 10 Flying the Thatcher CX4 and CX5 Prototypes.— CONTACT! Magazine’s editor Patrick Panzera spent a winter weekend in Pensacola Florida test flying both the well proven Thatcher CX4 and the newest addition, the two-place Thatcher CX5. 14 Ford Coyote 5.0L (302 cubic inches) 412 HP Crate Engine.— Another fire-breathing V8 crate engine that should make a great auto conversion for experimental aircraft. 16 RENO 2014. — Richard Lewis became the proverbial “ fly on the wall” during a dispute between officials and a pilot who was disqualified. His report on this is certainly newsworthy. 28 12th Alternative Engine Round-up, French Valley California— Last year we changed the location of our annual gathering once again, and we’re planning to do it again this year on Saturday, September 26, 2015. Please join us at the French Valley Airport near Temecula California! The fine people from EAA Chapter 1279 have again offered to cohost our annual fly-in and we appreciate them greatly! On the cover: Pete Plumb’s prototype DP-1, 100 cubic inch O-100, two cylinder engine based on the Continental O-200.
