| Subject: | Usable fuel--- gravity flow fuel systems |
Mike,
That was a timely post that I put aside until I had time to read it. 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.

I've attached a good fuel system article by Tony Bingelis but if you have
the books by Tony Bingelis he will show you how to install
a flawless fuel system and also show you how to exactly calculate how much
fuel you have that is usable an unusable in your system.
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!

| Subject: | setting up a Push to talk intercom |
Hello good people!
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.

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.

I'll cut the nose and rear of this rib free to use in the center section. As always,
I appreciate reading answers and opinions.
