My father John E. Williams was IE Mgr with Umbaugh 1959-1962 and VP Engineering/Production with Air & Space 1964-1966. I have a few pictures and newspaper articles I could share. Would like to know about Richard W. Bosse and what happened with the company since a few stories have passed down through the family.

My father was a department head for the Muncie Indiana Schools and investigated the employment possibilities for graduates of the vocational school. The company welcomed him and gave a complete tour of the plant. Where we lived there were many Muncie 18s flying over the house. I remember the different sound as compared to a cub or tri-pacer and father always went outside to watch them fly over the house. He was really sad when the Irving Brothers, owners of Air and Space closed.

David Rosinsky, e-mail, 01.10.2012 07:26

Well here we go. The Air and Space 18 A is on it's way to resurrection. Heliplane USA Inc. has brought the gyro out of financial troubles and is about to begin production. Presently, according to Gene, he has several aircraft that are refurbished with new engines and ready for immediate sale, and is taking positions for newly built units.

Interested parties can contact as West Coast Sales and Marketing.

Jean-Pierre Harrison, e-mail, 19.02.2012 18:17

The 18A uses blades originally manufactured by Parsons Corporation. They are of fibreglass-sheathed wood construction identical to that of the early Hiller and Bell helicopter blades. However, the 18A blades have no twist unlike the helicopter blades. Hiller/Bell and 18A blades are not interchangeable as they are designed for very different purposes and loads.

Anyone have any news on the disposition of the Heliplane/Ferrel bankruptcy?

Brun, e-mail, 31.01.2012 10:03


Can anybody tell which helicopter MR blades Umbaugh 18A used? Is it possible to buy non-flying 18A for restoring as experimental?

Thanks in advance,

Duane Ferrel, e-mail, 17.01.2012 22:25

I heard from Dad you were coming. I trust something comes together and we can get this bird flying soon! There is a lot of interest in the aircraft and even more so in the future enhanced models. Trust that the meetings will be productive and fruitful!

David Rosinsky, e-mail, 15.01.2012 07:30

Hi Duane, my partner and I have been working with your dad for nearly a year now trying to raise the funds to start production. I thought we had it all sewn up about 6 months ago, but it became a no go. I think we may have a good deal this time. So we are very excited to see the 18A fly again. We may be out in Florida next week or the week after to see the machine and parts. Let's keep our fingers crossed. By the sound of all these posts, it looks like alot of people would like to see this baby on the market again.

Duane Ferrel, e-mail, 30.12.2011 07:42

I forgot to mention, we have 6 aircraft mostly assembled. Need to get engines for several. We have parts for those who currently have 18A's and need them. There is a lot of interest in getting this going again...especially for the price point as compared to a helicopter. The new engine will make this unit faster and carry a better payload.

I saw 2 of these yesterday at the Santa Paula, CA airport. One was completely restored and looked like new. The other was a basket case looking for renovation. I am not sure who owns these two aircraft and we did not see the restored one fly.

George Gravelle, e-mail, 12.11.2010 19:00

I had the opportunity to watch the Umbaugh during the 1959 - 61 time frame. My dad was an Aeronautical engineer working on a drone that was being manufactured by Fairchild. We lived in State Line Pennsylvania and we were able to look down the hill to Hagerstown Municiple airport and the Fairchild plant. We would see the Umbaugh in flight a number of times and I always wondered what happen to the aircraft. It was such a pretty aircraft and was airborne in such a short distance. The Idea that it could be a family aircraft that could almost operate out of your back yard. I have been the industry for 47 years now and haven't run across any since the early 60's. Does anyone know of other U-18's that may be around. Another aircraft that we use to see at Hagerstown was the Custer Channel Wing. I was in the Civil Air Patrol at the airport and had an opportunity to see this aircaft several times. It's a shame this aircraft fell out of favor it was a beauty and for me the channel wing made sense. Thanks, to the early pioneers of these aircraft and the people that flew them. They helped me decide about a career in Aviation. George

Howard, e-mail, 13.10.2010 19:05

A fascinating machine..... It seems that all the jump machines have pretty complex systems.... particularly the 3 blade rotor that must have lead and lag and flapping capability as well as collective. At that point you are so close to a helicopter that there is little point in making the distinction.

My father, Max, was the chief test pilot at the Muncie Indiana plant that produced these in the mid 60's. I have fond memories of hopping around in the 18A with dad when I was about 11, or 12. It was less than a mile from the plant on the south side of the "Water Bowl" recreation area to the Delaware county airport. It is great that several of these are still in the air.

Ray Umbaugh, Jr., e-mail, 27.02.2010 02:16

I'm Ray Umbaugh's only son and would love any input people have about my Dad's U-18. Thank you

Dollie Matalon, e-mail, 22.02.2010 19:15

My husband, Leon L. Matalon, was instrumental in the designing and developing of the aircraft. When Ray went bankrupt and he suddenly lost the job, he was unhappy. He went directly to Fairchild after that . It really was a wonderful concept left to fail!.

Doug Poling, e-mail, 15.12.2009 19:25

As the former head of the 18a program for Don and John. Its really good to see there is still an interest in that ship. That airport was one of the neatest places to work great people.

Mr Farrington ferried a mccullough j2 that I bought In virginia, I forget the owners name but he was in the whiskey business, Don was very fair with me I was training at his airport when his father died, john took over my training, he was a mild mannered gentleman. I eventually gave up on gyroplanes, a hobbie best left to the wealthy, but will always remember my time down in Kentucky.

Kim Howland, e-mail, 09.06.2009 18:10

Anticipating my first airplane ride with an uncle years ago from the original Ocala airport, he stopped in the Umbaugh hangar to say hello to fellow machinist friends. His photo of me seated at the tiller on a flying prototype, without cowling or cabin, shows a delighted ten-year boy, wearing a freshly pressed shirt and big grin. Even though my shirt barely survived that mostly enjoyable first flight, it was still a great day in my personal aviation history.

Frank Zumpf, e-mail, 29.03.2009 00:37

My mother used to work at the plant in Bartow, Fl & I have a couple of factory movie films of the Umbaugh in test flights.

Rick Larsen, e-mail, 15.01.2009 17:09

My Dad, Howard Larsen, worked for Ray Umbaugh when I was a teenager in Ocala, Florida. He was a former Chance Vought engineer (Corsair). He designed the clutch/transmission package that sent temporary power to the rotor on the U-18. Earlier, when Umbaugh's team was working with the old Bensen copters (I believe I'm correct that they were Bensens), modifying them and conducting experiments at the old Ocala airport, one man dropped about 100 ft and was killed on the tarmac when he pitched the rotor back into the pusher prop and lopped off the rotors. I was in CAP and used to hang around the Umbaugh hanger watching the test flights. The U-18 designs flew okay, but were not what you could call 'hot dog' flying machines. They kind of dangled on the rotor and flew like a large beetle--no quick motions. Umbaugh had a big community turnout for demonstration of one of the series and did several takeoffs and landings flying dignitaries and family around. This was late '59 or early '60 as I recall. Always wondered what happened to the machine. I thought it was a pretty slick design. --Rick

Scott, e-mail, 25.08.2008 22:49

I grew up near Farrington Airpark, where my dad learned to fly. I kept my own plane there for a while and even lived there in the Summer of 1992. I have some great memories of John Potter as well as a great story of Don Farrington test-flying a TwinStarr that I saw with my own eyes. I'd love to see a book of both John's life and Don's as well. Farrington Airpark (FIO) was ione of the last true "grassroots" airports, and there was always something going on. Sadly, Farrington Airpark is now privately owned and is being operated as a drag strip. Dr. Blane Grow still uses the strip for his own airplanes, which are kept there.

Tom Calovini, e-mail, 29.05.2008 02:53

In the early "60"s I ran into the 18A when I was fresh out of college. In my mind this was really going to be the "Model T" of the air. Becoming immersed in the giddy climate of all the Dealers congregating in Hagerstown,MD at the Air View Motel and seeing the prototypes being flown almost daily out of the Fairchild Facility everyone just knew this was going to be the first real mass produced, everyman's airplane.

John Potter was a part of the fabric of the dealer organization and committed himself and all his resources to the cause. I was lucky enough to befriend John and spent countless hours traveling the country with him in his trusty Navion "4032K". It always seemed John would show up when you thought of him.

It was a tragedy not just for John, but for all of us who dedicated our lives to getting the project off the ground, but the inspiring thing is that John never really gave up the dream and was still pushing to the end.

It was an honor for all who were his friends to know John and I would say he was one of the most inspiring and dedicated men to grace aviation.

We miss you John...Tom Calovini

I am interested in knowing where to buy this airplane. or who knows to mount a distribution in Brazil.

Jon, e-mail, 29.04.2008 21:58

No, it is out of production. Don Farrington (described in the article above) was doing re-builds but died a few years ago after a heart attack at the Sun-n-fun airshow in Florida. There is still a parts inventory in existence. I fly one regularly. I know of one in zero-time condition that is for sale; see this website:

Is the gyro 18-A still produced.?? I would really appreciated if somebody can inform me if those gyros are still produced?? thanks

That was me flying through Harris Ranch/Coalinga that Dan Humphreys saw in 2007. The aircraft is now based at Palo Alto; I was ferry-flying it out from Houston at the time.

Woody DE SAAR, e-mail, 04.03.2008 21:00

Hi there .

I was working for the Farrington Aircraft Corporation from 1993 until 1996 as flight instructoron the 18-A and later also the Twinstarr (to which I now own the manufacturing rights). Your information is fairly accurate. If you need more info or clarification, please do not hesitate to contact me.I have been working day-to-day with the company for over three years and it was a fabulous time.


Wayne Schober, e-mail, 08.02.2008 08:44

I have Air&Space 18A N6117S. In 2004 it was completely torn down and inspected by John Potter at the Paducah facility I helped him during the inspection. I was impressed with the quality of workmanship and construction. It is a robust, aircraft-quality machiine. It has subsequently been trailered to and stored indoors near Albuquerque NM. The overhaul included installation of all pertinent STC mods and 720 chan radio and Mode C Transponder.

The airport it is based at has an Instructor/DE for rotorcraft.

I am considering sale of this gyro due to time constraints. Haven't fully decided.

Contact me for more.

My father was a Muncie, Indiana school administrator at the vocational (trade) school in Muncie. During the early life of the Muncie 18 he was detailed to determine if the school system could assist in the suppling of trained workers from the "trade school" but nothing ever came of the program for certified welders. Oftern we saw these air craft being tested or sales flights from our home on the west side of Muncie. I remember the owners of the company,Irvins, saying they were working on a military version and a pipe line version of the plane.

I was directly involved with Don Farrington and John Potter. I was probably John's best friend in the later 15 years of his life. There several web sites with the early history of the 18A but they are not quite correct in some ways and they are all coppies of each other. I have been trying to write a more complete story when I saw this web site, it is the best I have seen. Actually tyhere were 4 tail designs and I have a picture to prove it. It was simular to the T tail but with two large fixed fins on either end of the horiz. stab.
I am also putting together info. for John's story, it was an amazing life. John died about the 28th of June 2006.
Would you like to use my writing, maybe to add to this web site? Kind Regards - Rob
