I'm with you Walt. The reason I decided to build an airplane is to indeed b uild it. I have learned so much by taking on tasks that I knew virtually no thing about. -In my estimation, that is what is so much fun about the pro ject. The design,engineering and fabrication. Yes I could have been flying by now if I were to have purchased ribs, hinges, etc. but the value of bein g able to say those words (above) trumps everything.

He locked and safety wired the mixture control on my A-65. He said that you don't have to worry about mixture till 10,000 ft or so. Don't know how high you plan on flying with the "A" Also don't know what type of fuel you'll be using. But he said that if using auto fuel, because it's so volitle, that it can start gassing off at about 6,000 ft, with a chance of vaporlock. In other words, he was more worried about the auto gas than the mixture control. walt evans NX140DL ----- Original Message ----- From: John Smoyer Sent: Sunday, February 01, 2009 7:36 AM Subject: Pietenpol-List: Model A mixture control Hi, Guys, Have any of you installed a mixture control on your Piet's Model A engine? With the engine turned 180 degrees from what it would be in a car, I can't figure out how to rig a control that will adjust the mixture from the Piet's cockpit. Any thoughts or recommendations would be greatly appreciated.

There is a possibility for more efficiency, too. BUT, these potential gains must be balanced with the drawbacks of having a more complicated air intake system, the potential for carb ice forming, and the potential for the carb/engine combo just not "liking" the colder charge (for instance, the fuel might not atomize in the same way in the carb throat with colder air).

Pacific Standard Time, taildrags@hotmail.com writes: Joe asked- > Also on the turnbuckle topic; has anyone replaced the piano wire on the tail > with cable and turnbuckles? > What size cable and what size turnbuckles? I don't know of anyone who is currently building a Piet using the steel wire and thimble method used in the old plans, although it has been done in the past. Most everyone uses 1/16" or 3/32" 7x19 cable with turnbuckles to adjust the tension. My airplane uses 1/16" stainless cable back there since the first set of wires on it (galvanized) had some corrosion over time and I replaced them with stainless. A quick glance at the Aircraft Spruce catalog shows that the turnbuckles for 1/16" cable are just about the smallest ones in the catalog listing.
