Hi All, I am fitting my homebuilt with instruments and radios, and wanted to add a Direction Finder. I wanted a doppler type, but with small antennas in a 4 point aray with a small dimension or distance between the antennas. Am I really far out of reason, or is this an achievable goal? Charlie

I am adding two regulators to my welding system for welding aircraft parts with a little Smith Airline torch system. I was able to but two excellent new Craftsman acetalene regulator ver y cheaply. I am going to add these regulators to my little portable welding table and rig my hoses from the...

Is there an easy way for a novice to check an old antenna? thanks et

I've heard of prepregs which have the resin and hardener separated within the fabric, which can be activated by applying pressure with a squeegee or similar tool. I searched the internet but I can only find the standard premixed prepregs which need to be kept in a refrigerator and cured at elevated...

A short time ago someone had posted a link to a tool that could hold a screw so you could drill a hole for cotter pins. I thought I had bookmarked it but just can't seem to find it. Could anyone help? Lou

Hi Lads, I'd like to build my own aircraft while I learn to fly. A friend has recently bought a secondhand Jabiru 160 (is getting a new 230c) and has 150 hours up on a Recreational licence. Although I would love to build a Falco or even one of these (www.spitfireaircraftco.com), I think the...

Someone gave me a Speedaire Model 3Z394 airtank. I know nothing about its integrity or working pressure. 1. If you own such a model, could you tell me the max safe tank pressure? 2. How can I determine if the tank (which as some rust on the outside) still has its integrity? - Mike

Ok, I've made a few pieces to try out using 1/4" foam and fiberglass on both sides. When I cut the pieces to shape with my band saw, small strips (1/4" or so) seem to want to seperate. Is this common or did I mix the epoxy wrong? The big parts are staying together, the fiberglass itself is staying...

I know that just about everybody has bad-mouthed the 2si, but what are your opinions of the Hirth series?

Anybody have any opinions as to the various strengths and weaknesses of each?

I have seen lots of stormscopes on e-bay lately. Any recommendations for or against any particular model ore manufacturer? Dan, U.S. Air Force, retired

I have a cont A65-8 45 SMOH is there a way to get fuel to the carb, while doing aerobatics? can I install an electric fuel pump? or will I flood the engine?

I am to the point that I must cut the holes in my panel. Does anyone know of a source for full sized instrument faces in paper or something. I would like them to place on the panel to have a full size view of the layout before cutting. The layout could be shifted around until I find the...

A while back I remember seeing an article in one of the aviation magazines about the affect of squared off trailing edges on control surfaces of light planes. Anyone know where such an article might exist? So far I have found several Boeing and NACA publications on wings with blunt trailing edges,...

Here's a weird one. Anyone know if pocket protectors are still available, and if so, where? Hopefully somewhere not involving mail order. Seems strange, that I would think about something that so many have made fun of, but I'm sick and tired of pencils and stuff falling out of my shirt pocket,...

I've noticed that a lot of aircraft put trim tabs on the trailing edges of the normal movable control surfaces. Wouldn't this just deflect the control surface to neutralize the forces and not affect much change except drag? It seems like you'd want to put the trim tab on the fixed part of the...

There seems to be some jealousy and bitter bigots trying to bad mouth this plane its ebay listing in addition to defaming me. This plane is priced to sell and built professionally and has hundreds of hour flown off of it safely. I refuse to have dialouge with any of these Keyboard Rangers...

Hello all, These may be a bit heavy for an ultra-light, but I guess whoever has an interest will know that better than I. I have in my garage, two Augusta 42hp twin horizontal crankshaft and cylinder gasoline engines in their factory crates. They were sold by Augusta to the National Research...

We had a cold front pass through Friday evening here in New England, and the forecast was for cool abeit windy weather for Saturday, with the cool remaining on Sunday but the wind diminishing somewhat. Great weather for sandblasting, I thought. Did I ever mention how much I hate sandblasting? ...
