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

I originaly posted this to rec.av.ultralights but thought you folks might have useful iformation and insights.... I'm contemplating building this combination and would love opinions. The reasons for this choice is combination of price (I would like to keep as low as possible) and my ability to...

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...

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

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...

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

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...

Hi all,Â* I started studying Jim Marske's Composite Design Manual to understand composite techniques generally and glider construction in particular.Â* My current topic of interest is the best design for joining two plug-in wings for a small sailplane, say in the 13 meter class.Â* It seems the...

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...

For anyone who knows: I have the plans for a Lasher Renegade, a VW powered Formula V race plane that I plan on using for sport flying. I was given them in 1980 and they have been gathering dust while I support my children. Now at 50 years old, I am finally getting my chance. Unfortunately for me,...

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...

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...

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

They will be attending the annual national convention of the Soaring Society of America, open to the public from 9 a.m....
