Situation with experimental airplane: Gravity feed tank with Lyc IO320B1A fuel injected engine. Gravity free fuel flow is greater than 20 gph and the engine burns 15 gph at full throttle take off. Cruse fuel flow 7.5 to 8 gph. I want to test the engine without the engine driven fuel pump as I feel...

Having a "better G" idea, decided to hang my engine on M1 fuselage without wings in order to have the ability to roll it outside the hanger for breakin efforts. After struggling with several versions of a wooden framed, wheeled "wagon", a thought occurred that I may be "reinventing the wheel"...

Hi all, I am a complete newbie to the world of riveting. I have to do some and I know nothing about it. It *IS* aircraft related, though not directly. I'd appreciate any help I could get: I am refurbishing a old P-series flight helmet. They had leather oxygen mask tabs, with snaps, on the sides...

Looking for new or used plans for the Capella aircraft. Thanks Neal

I am doing some preliminary planning of the panel for my RV-9A and wondering if a 2nd nav is really a necessity with a GNS 430 in the panel. Seems to me that flying IFR GPS, with mostly GPS approaches in the near future, I should not have much need for a 2nd VOR receiver to identify intersections...

I've got a stainless AN fitting (that came with my motor parts) that I could use some help identifying. Photos and explanation are posted: http://www.weldingfaq.com/turbine2.asp#fitting Thanks! Larry

Looking for some input: I don't really see a need to buy several different colors of electrical wire for my homebuilt when you can easily use just one color (white?) to do it all. The only thing you then need to do is to mark the ends of the wires to identify the circuits and where it all goes...

I have a panel mount Microair transceiver and Xcom Intercom in my homebuilt. I also take along a Vertex handheld transceiver when I fly. Does anyone know of a small, (space is very limited), audio panel that would allow me to switch between the Microair and handheld?

I have a print that, as best I can read it, calls for a fitting # AN 867-6. Is that a standard 3/8 tapered (NPT) thread fitting for welding on fuel tanks? Can anyone point me to a chart that has pictures of the AN fittings and possibly a translation to equiv. pipe or tube specifications? -- Bruce...

When welding, say, a strap across a variety of thicknesses, for example a tube, then a weld then a cluster wiht a lot of welds, I find it neccesary to stop the weld and change tips. is this acceptable practice?

I bought an Icom A6 radio at SnF from Pacific Coast Avionics. I tried to register it to get the warranty going and to get the rebate. When I try to do it, it wants to know the "UPC," but it won't take what I give it. What I give it is a number underneath a piece of paper that someone obviously...

Hey all, When laminating several fibreglass tape layers over the fillet in a T-junction, do you use the widest fibreglass tape on the first or last layer? I've heard different answers from different sources, so is anybody here doing this right now for a kit and what do your kit instructions...

I'm trying to figure out which glue to use for wingtip bow laminating. I've been using aerolite up to this point for my woodwork, bu tI'm told this is unsuitable for bows due to it's fast setting time. I'm thinking T88, but am open to suggestions. naturally it has to be strong, but I also ned it to...

I need to design a device to help "cushion" the engagement of my starter. The starter is 28VDC (drawing up to 500 Amps) on a T58-GE-3 turbine engine installed in a non-aircraft application. I'm told this "starter slamming" is a 'weak link' on this engine and often causes starter failure.

Hi- Does anyone know of or have an Avid Catalina or Amphibian for sale? Anyone built one? Thanks! Douglas Gurney

Does anyone have a formula or (table of values) for atmospheric pressure at various altitudes? 1,000 foot intervals up to FL330 on a standard day is all I need. Thanks in advance, Dan http://www.scuba-training.net

Hello to all homebuilders! To be brief, I am planning to build an airplane and I am strongly considering the Zenith Zodiac XL. It suits my purposes nicely, and I could fly it under the Sport Pilot rules if the need arises (i.e., in case someday I need to make use of the driver's license medical...

Ok Guys and Gals, I do not remember the formula for this to save my life, so I will see if yall can come up with it. Yes I did check on the web, but did not see the formula I need. I want to figure the volume of a gas tank that will not be round or square, It will have five sides and then the two...

Hi all, I'm looking for a line drawing type vector graphic of a top view of a cessna single engine, or other single engine high wing plan. I can convert the one in the cessna manual by scanning it, converting, and retracing it, but I thought I'd check to see if anyone else has done it yet and...

I have come across a small amount of aluminized fiberglass. Any idea what it would be used for? I'm just going to be using it for some nonstructural widgits and it was free. Dan, U.S. Air Force, retired
