How is the 51% rule line drawn? Let's say for example I want a homebuilt Comanche with my own choice of engine and I locate a set of plans as well as the wings and tail feathers from a factory Comanche. If I build the fuselage from the plans and recycle the wings and tail, is it an amateur built...

Does anyone know of an article about a checklist for the 51% rule? I remember reading the article and would like to find the website to download it. If I remember, it was a checklist of what parts and components would be built to be considered 51%. For example, if you start a kit but do not quite...

Lot of stuff lately about revisions/modifications to the FAA's enforcement of the 51% rule. We don't really need it. Here are the Top Ten Ways an Inspector Knows that an Amateur Builder Constructed the Aircraft: 10. Bloodstains on plans seem to emphasize the middle digit 9. Builder knows how...

Does anyone know the power and weight comparison between a rotax 583 vs. geo/metro engine . When I said geo/metro I'm not too up on them , so I suppose I'd be meaning the most powerful carburated one that is non- turbo . Thanks Ed

Instead of the Javelin Ford, which appears totally dead, or the Chevy V6 that is 3/4 a small block has nayone thought about flying the pushrod Chrysler V6? They are becoming available pretty cheap.

Hello, Does anybody have knowledge about using aluminum alloy 6005-T5 for a wing spar extrusion in replacement of 6061-T6 ? Apparently it has the same properties and is more extrudable. I am concerned by the "same properties", especially fatigue; but cannot find anything on the subject and I am...

Anybody knows one? I failed to find any in the Net. Thanks in advance, MT

I just listed another 1961 Cessna 210A on ebay for auction. This one has 40 since major overhaul on the engine, accessories, systems, and one year since new paint and leather interior. Reserve price is less that 2/3 of the AOPA appraisal value, so you can fly away with a no- problems at a very...

I have just listed a friend's really nice 210 on ebay. The airplane was maintained on a Part 135 certificate, owned and flown by an A&P- IA / Airline Maintenance Inspector for a specialized medical transport business. This is an excellent opportunity to get a no-problems, well- maintained mid-time...

I'm considering a Nieuport 11 ultralight, and I was wondering if anyone here has flown one, or heard anything about how they fly. Will they fly hands off, or do you constantly have to stay on top of things? Are they easy to ground-loop?

On another site (Emerauders.com) It was mentioned that a retired Aero engineer in Texas had built a P-38, there were pics, but I was unable to open them. It was all metal with a jump seat for his co- builder (wife) Has anyone seen this aircraft?

I know this will not do much for unbelievers, But I have no problem believing that an 1835 engine with a belt reduction system would fly an airplane with a takeoff weight of 1050lb's.. The performance didn't look to be that bad either. I think a good 1835 vw engine with reduction can do...

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

If you up there in the Cockpit, look out of the window and see an Lawnmower, don't be alerted, you are not crazy. They now have flying Lawnmowers. The same group of Hobby-ingenieurs also developed a flying doghouse and working on a flying Washmachine and a flying...
