Looks like a tiny propeller. How can it make a big plane like that fly to such a height? http://www.youtube.com/watch?v=216D3WvspN0

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...

Hello, Is someone knows this alternator? http://www.ecae.com/alt1.html part number 2025 or 2026 2lb more heavy than kubota but 50A vs 15A....

We're making propellers over on the Chugger's Group. Right now guys are mostly gluing-up the blanks that will become propellers. One of the things that needs doing is creating the TEMPLATES that will be needed in the final stages. The templates are in the Files archive, full scale, so all we...

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...

Hi all, I need to buy a new handheld GPS and would like pilot reports for the Lowrance units like the Airmap 2000c and 600C. Likes, dislikes, etc. Thanks Dave

I've had an interesting experience with Aircraft Spruce and I'd like to know if this sounds like normal business behaviour. I have a number of instruments in my Rans S6S which were purchased from A/S about 3-4 years ago. I kept the accompanying forms in a binder for reference. During a burglary...

I was just looking back through the EAA Modern Mechanix Flying and Gilder Manuals. None of the aircraft depicted were pushers -- except for the Wright Flyers and some early Curtiss. In poking around for old flying boat designs, I've found lots of pushers. Does anyone know of any home built...

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

I am working with plans circa 1963 that call out 7075 T6 1" angle. Anyone know if it's still manufactured? Don't see it in ACS or Wicks. Thanks, Clark

Does anyone know where I can get plans for building my control stick on the side instead of in between my legs. My plans call for in between the legs and I would like to look at other options. The problem is I can buy a full set of plans but which one? Anyone have an idea? ...

I need one of those rubber stamps that say 'I certify that this aircraft has been inspected in accordance with------". They used to be advertised all over a few years ago, now I can't find one anywhere. Can someone give me a lead? Thanks

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,...

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? ...

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
