I have a wood prop on my Taylorcraft and the GPS says it's slow, at around 65 kts. How about a discussion on the relative merits of wood and aluminum props. I understand that wood is easier on your engine but the aluminum prop is more efficient. Another thing I notice too, especially on...

Would anyone be kind enough to point me to a wiring diagram for a general aviation radio? I need to know the pinout configurations and voltage for the mic connection. Thank you and regards in advace! Gary

This is probably going to open old wounds. What I would like is experienced input on the advantages, for economic, efficiency and longevity etc. of different types of redrives. I am leaning towards a cog-belt reducer in a 6 cylinder, liquid cooled, configuration driving a long drive shaft to the...

To All: As promised, I've began posting drawings of primary glider(s). You will find them in PRIMARY_GLIDERS Group, in the FILES archive, in the Folder 'The Northrup Primary Glider.' So far I've only posted a few. The others will be posted as time -- and my medical condition -- permits. The...

Hello All, I am strongly considering the RV-7a and am interested in knowing the dimensions of the baggage area behind the seats. Thanks David

Is the A/W-95 Helicopter by A-B Helicopters a good design for what it is ??? I'm thinking of building it but appreciate any advise . Thanks ED

Any survivors out there? Posts are 20 plus years old. Just bought 1 partially disassembled and need some help acquiring / fabricating wing struts and then pontoons. Thanks, GE

The two main methods for homebuilt construction would be casting vs. machining or some combination of both (probably the best option). Forging probably isn't appropriate for home construction (either the piston or connecting rod). One method I have thought of is to produce a wax model of the...

Why do we homebuilders use 4130 tube? My old Aeronca does just fine being made of mild steel. A bit of napkin calcs says that going up just one tube diameter for the size tube we normally use, the area, and the strength/weight goes up between 15% and 20%. This pretty much offsets the difference...

Ok, one more round of it: does anyone have a set of Airbike plans for sale, or know of the German website that was/is producing them (newairbike.com)? Thanks

Hello, does anybody have drawings/plans or any other technical documents about the Bucker Bu 133 Jungmeister (or know someone who has)? Thanks in advance for the answer Kai Glaesner

I'm working on a Hummel Aviation Ultracruiser Plus. The way the engine mounts is quite different from the mounts on most VW powered homebuilts. The Conventional Wisdom bolts the thing to the firewall using the clucth end bellhousing, often with an accessory case in between. The Ultracruiser Plus...

You blithering idiots! You re-elected that imbecile George Bush as your President. He’s a complete moron and so are most of you! - Which still leaves us well above you! Don’t you care what the rest of the world thinks of you? Don’t you care what

Have they tried dimples on radio controlled aircraft? The size and speed could designed around the magic Reynolds number = 100,000 where the coefficient of drag drops precipitously. Dimpling could vastly extent the range of large and slow as well as small and fast radio controlled aircraft. A...

I am involved with the building of a velocity, and questions are flying around about propeller choice. For in-flight adjustable, we are limited at this time to an electric control, such as MT or IVO. Cost is pushing our options in this area towards the IVO. I have heard of some vibration/resonance...
