Actually, I believe the Avian got certificated in the U.S., but they
ran out of money before they could get any made and sold. The Air &
Space (Umbaugh) and McCulloch were the only 2 that ever made it into
production. Neither made over 100 units if I recall. I have Mac # 72.

Hey Ken,

Shouldn't you now be called KenNorthCarolina now? <g>

I was thinking of the ducted prop idea.

Yeah, Ken

Somebody was trying to re-launch it as the "Pegasus" a couple years
back. Their website is still up:

http://www.pegasusrotorcraft.com/

I thought it used Hughes rotors like the other two certified gyros do
(I think?) but the FAQ (which is a .pdf, warning!) says that their
craft is immune to ground resonance because the rotors can't go out of
phase. I'm having trouble figuring out how they built it without
lead/lag hinges.

The 18A was produced by Umbaugh, Air & Space, and Farrington. According
to Aerofiles, it looks like 110 Umbaughs, 68 Air & Space, and an
unknown number of Farringtons were built. I personally doubt Farrington
constructed any new-build ships.

The whole entry on the McCulloch does not suggest any population. It is:

Helicopter Div, McCulloch Motors Inc, Los Angeles CA, Lake Havasu City
AZ. McCulloch Aircraft Corp, 119 Standard St, El Segundo CA.

J-2 Gyroplane 1962 = 2pCAg; 180hp Lycoming pusher; rotor: 26'0" length:
16'0" load: 550# v: x/105/28 range: 300; ff: 6/x/62. $19,950. Twin
booms and tails. Landings and take-offs in 75'. Prototype {N217M].

(There was an unsuccessful helicopter in 1951)

I think J-2s were marketed until at least 1972. Silas Smith is (was?)
selling one he said was a '72 with low hours. (~50).

Rejean Laflamme in Quebec owned and flew both the J-2 and the 18A. He
preferred the roomier 18A but disliked some of its handling
characteristics. He fought a multiyear battle with Transport Canada to
license it.

Rule #1: Don't hit anything big.

Correct me if I'm wrong (very pften I am <g>), but I believe they only
use the blades, not the entire rotor system. I also believe that the
blade are/were installed upside down.

Uh that should have been:
