Subject: Pietenpol-List: EA-81.When I start back on my piet, (moved into new home) I am going too startmaking plans for the motor mount. My question is the soob is underweightcompared too the "A" engine by 50lb or so. How far forward from the firewall should I design the motor mount for best weight distribution.ThanksSteveSteve W - Pietenpol in construction!GN-1--<(next project).IHA #6________________________________________________________________________________

Hi All,In view of the recent spate of discussion on tachometers, I thought that Iwould mention that I have a beautiful, new, never installed Stewart-Warner,model RT-7 mechanical tach for sale. It is 3 1/8" diameter, 3500 RPM, 270degree sweep, built in Hobbs meter, all black with white lettering, nogreen/red range indicators and no cable. I'll take a hundred bucks (US) forit. prangel(at)psns.navy.milKeep Fly'n,Larry________________________________________________________________________________Date: Fri, 19 May 2000 11:01:08 -0600 (MDT)

Kirk, Moving the wing back on Piets is the time-honored way of adjusting CG for different weight engines. This solves the problem when installing the lighter aircraft style engines. You could also extend the engine mounts to give the engine a longer arm. You could also build the extended fuselage version of the Piet which was designed for the Corvair engine by BHP himself. That way it's still a "real" Piet! One thing I like about adding the length ahead of the wing is that it keeps the wing a little more forward and aids ingress/egress a little. I plan on building the longer fuselage, with the wing a few inches higher than plans, this does make the Piet a little heavier, but roomier too - everything's a trade-off! Find a Piet locally and take a million pictures, buy the builder lunch, and ask them a million questions, that's the best way to get a feel for what can be done with this design. Biggest thing though, don't let little questions stop you, I don't know where you are in the buidling process, but while you're figuring this stuff out, there's no reason why you can't also be gluing ribs or tail surfaces together! Listen to JimV though, he's been around the block a time or two on this Piet stuff! There's just lots of different ways to skin this cat!Good luck!Gary Meadows________________________________________________________________________________Date: Sat, 20 May 2000 05:31:26 -0700 (PDT)
