    I am seriously considering building some 4130 tailfethers for the GN-1. I would really be interested in knowing what the weight differences would be...which is really heavier. If wood is lighter, I would just keep wood taifeathers. Anybody know? Thanks in advance.. Larry Read this topic online here: http://forums.matronics.com/viewtopic.php?p=388152#388152

    I have ForeFlight as a trinket on my ipad/iphone. I flew 4.1hrs one day with it to go pick up some spare tires/brakes, converting my GN-1 to a freighter(front stick out). I have the little hockey puck-style gps antenna (xgps150). I just wear my usual hawaiian shirt, put the 'puck' inside my shirt on my left shoulder, and keep the iphone in my front pocket. Works great..figured my landing fuel to w/in one tenth of a gallon. Having all of this is neat stuff, but now that I have a new 406 ELT/gps's...antennae on my center section wing. I am now thinking that it is taking away from the magic of yesteryear and going back to the good ol' barnstorming era of Pietenpolling. I left it all behind (including handheld) on my last sortie. I felt the difference in enjoyment. Flying w/out the geek stuff was much more relaxing, keeping the eyes outside to enjoy the farmlands below. This is why I wanted the open cockpit antique-style machine in the first place. Larry Read this topic online here: http://forums.matronics.com/viewtopic.php?p=388153#388153

    Thanks for the input. I appear to have quite a few options to consider. I have an old iPaq- based gps/xm weather system that was pretty temperamental but that I liked when all connections were working. I've heard great things about Foreflight. Don't know much about WingX. Lots to learn. Connected by DROID on Verizon Wireless

    This came in on the RV-10 list, but I thought the Pietenpol community might be interested in it as well. Jack Phillips NX899JP Smith Mountain Lake, Virginia --> RV10-List message posted by: Rick Beebe <richard.beebe@yale.edu> The EAA Board had its Fall meeting yesterday. Among the items discussed, we agreed on the next 5 years of the site development plan and authorized money for this coming year which will build another rest room facility near Theater in the Woods and Vintage cafe, enhance the entry gates and start work on a new Homebuilt Village. We're going to tear down the decrepit hangers across from the homebuilt headquarters (where the "Federal Pavilion" and "Innovation" hangers are), remove all the pavement, plant grass and that whole area will be where the homebuilt exhibitors are. Homebuilt Village won't be done for this coming year but should be for the following. We also voted to not allow chalets on the flight line. The Aviators Club will remain as it's proven very popular with the members. We had a lively discussion about Sport Aviation and agreed it needs more homebuilt content. The Homebuilt Council had a 90 minute one-on-one with Mac about it. There is a sub-committee working on a bunch of bylaw rewording, mostly because the current bylaws are out of date, but also to include some governance changes. Revamping the proxy system is also still in the works. We agreed to set the size of the Board at 21 Class I (elected by the members) Director--3 groups of 7 who get elected for a 3 year term. There are 9 Class II Directors--heads of the divisions (Warbirds, Vintage, Homebuilt Council, etc.) and the EAA President. And up to 11 Class III Directors, appointed by the Board for a 1 year term. The Bylaw changes will be voted on at the next Annual Meeting at AirVenture. The issue of member access to Board minutes is on the table and being worked on. When they're available I'll let you know. There is a project to consolidate and simplify EAA's 23(!) different web sites. With all the staff changes, the museum has gotten short shrift of the past couple years and that will be an area of renewed focus. A sub-committee will be putting together a plan for our Spring meeting. Frank Christensen's Christen Eagle II, serial number 1 is now hanging in a place of honor in the aerobatics area of the museum. It's a very nice display. Finally, Jack Pelton continues to volunteer his time to guide the organization until we can hire a new president. That process hasn't started yet, but will shortly. --Rick

Mr Pietenpol liked to turn the engine slower for wear but i wonder what you guys consider as maximum rpm on the A.. with a 76 inch prop i figured 2500 rpm still had the tip speed under 75% the speed of sound if i remember my math... of course fuel consumption would be higher too if it would even turn that fast Jeff waiting on the DAR Read this topic online here: http://forums.matronics.com/viewtopic.php?p=388170#388170

    So, 2" of pitch reduced rpm by 200? My old Jones tach is inaccurate, so I got the 1980 from an electronic strobe-type tach checker. Wish we had definite comparable numbers.

    I agree! This is an important topic. I'd really love to see what the difference is between a 76 incher and say a 79 or 80 inch prop with the same pitch and blade design. With the A's torque, I think it would handle a larger prop well, as long as you have enough ground clearance. Gene: I have an 80 x 34 Price prop. Want to play with it some time?
