I have a use for my David Clark ISOCOM intercom, P/N 18486 G-01, but I've lost the pinout information. Can anyone supply this?

Thanks,

Since the problem is sensitive to frequency (ground vs tower) I suspect the antenna or the way it's mounted, in which case the ferrite might be the best solution.

Can you show us what the spreadsheet looks like? An image would be worth a thousand words.

I'm building a CH650 with the taildragger option. Can I expect the empty CG to be more forward, aft or the same compared to a comparable equipped nosewheel CH601/650?

I can probably calculate the ...

Thanks everybody Very Happy

Great advice!

I've decided to replace the rubber hose fuel line from the tank with 3/8" aluminum line. I've got 2 questions - should I use 6061-T6 Aluminum line and what wall thickness should I use? Aircraft ...

my A&P used a mold made from aluminum. he pluged the end of the mold with clay.after it cooled , he used a file to

What's used to plug the tubing before pouring the molten lead in?

I used lead on the inside of the tube to a depth of about 6 inches, then it only took a couple of plates to completely

Thank you all very much!

Since the factory is recommending shielded wire (probably just CYA) and because I have some, I'll just tolerate the added few ounces. The factory, like Rick, suggested con ...

I'm in the process of installing an AveoFlash combination LED position light and strobe. I'm getting mixed signals on whether or not I should use shielded wire on the strobe line.

Since everyone (including the manufacturer) says I shouldn't need shielded wire, I'm going to go with standard wire and save the weight.

Thanks, everybody!

I ran about 15 feet of wire from a battery to the strobe. When an AM weather Band radio was anywhere within 10 feet of the circuit, there was considerable noise in the radio.

I didn't get any info ...

I'm getting ready to install an Aveo wingtip LED stobe on my all-aluminum wing. I ran some bench tests and found quite a bit of switching noise on the stobe wire. I'm assuming I should use shielded ...

A 2 part mix sounds like an epoxy, which seems like overkill for an application like mine. It seems like I should be able to use a non-hardening Permatex form-a-gasket type of stuff. Am I wrong?

I'm adding a bulkhead AN fuel line fitting to my fuel tank and am wondering what to use to seal around it. I've heard of Proseal, but I don't know what it is or where to get it. I want something tha ...

I think most of my confusion resulted from confusing the rear attach plate with the root doubler (6w7-2). The root doubler is also 0.063 on the 601 wing.

I'm much less confused now. Thanks for th ...
