I am rebuilding a Baby Ace that suffered a bit in an off-field dead stick landing. While flushing the tank, and checking for residual contamination, I noticed a very poor rate of fuel flow. The pictures are self explanatory. Gary Boothe NX308MB From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Cuy, Michael D.

I have a 17 gallon nose tank and I did the prescribed static fuel flow measurements for my Piet setup on a earthen barn ramp that was in the back of an old farmhouse I was renting while building. The barn ramp simulated my plane at a climb angle and the fuel flow was measured into a Rubbermaid iced-tea container which had both ml and oz graduations on it. That, a stopwatch on my watch (now cell phone stop watches work great) and some fuel and I all I needed. The method Bingelis suggests puts the plane in a climb attitude and his calculations account for a full-power climb out situation. Those four books are worth their weight in platinum or gold (depending on which is higher!) Best $89 you'll ever spend on your Pietenpol! https://www.eaa.org/en/eaa-shop/homebuilders_corner/2251598800000__bingelis- set-of-4 Mike C.

I have a sigtronics intercom and would like to set it up with PTT for intercom, not voice activated. I don't want to spend much money (My wife says I am cheap, I say I am frugal.) I want it so that both the pilot and passenger have to push a button to talk to each other. I would like the passenger to be able to hear my radio transmissions. I want to install them on the stick. I have a grip with buttons for both intercom and radio (and bombs, rockets and guns!) for the pilot. (I have a wood knob that I can drill out for the passenger.) How do I hook that up? I do best with pictures. -- Blue Skies, Steve D ________________________________ Message 3 _____________________________________ Time: 03:30:28 PM PST US Subject: Re: Pietenpol-List: setting up a Push to talk intercom From: Marcus Zechini Steve: I think PTT is the way to go. I have vox, and have just figured out how to get it to be usable - leather mic covers. It's still difficult to communicate. I have a PTT input for pax, but I am trying to wire pilot stick mount (as opposed to handheld's PTT) before geting that ambitious. I butchered an old velcro yoke mount PTT and really have only used it to make a schematic. I DID get a couple of switches from Radio Shack before they will go under. In the mean time I moved hand-held to left side. I am lefty, so, of course ambidextrous and find left-throttle right stick natural. I look forward to seeing others post. I have wired mine at home, but after soldering connections it never works. Grrr.
