Barnet Rolling Frame

PRA was contacted by Debra Givens about her late father's Barnet Rolling Frame. Is there anyone who is interested in buying this from the estate?
She ask's: Is this something that would be of interest to your members? If we decided to complete the building of the aircraft, do you know who we could hire?

Construction on the airframe was accomplished by my father many years ago and the FAA initial inspection and approval of the welds was completed shortly thereafter. The airframe includes precision welded aircraft steel fuselage, horizontal and vertical stabilizers, rudder and pedals, engine mount, landing gear and wheels.

She has some photos and paperwork per-haps it's the build log. She is going to go find it.

Can any of you tell me/her what it would be worth?

Should they finish it?

Greetings rototheads.

She also just NOW emailed me a picture of the mold for the fiberglass body her father made.

This could be worth more than the frame as you could buy it and sell body's over many years. Either make then or rent the mold out?

I've asked if she could take a picture of the inside to see how finished it is.

I guess that this is probably for something like 0-200 engine ,where is it located John
Hi Jan
Yes IIRC the Continental O-200 is the standard engine for the Barnet.
The paper work says Yuba City California. I believe that is where it's at but did not ask yet.

That is a Barnett J3M. I believe the first in the series of his welded 4130 gyroplane designs. The J3M was designed for a Continental A65 - A80 motor that swung a 57" diameter prop. The design only had room for an 8 gallon fuel tank that was mounted below the seat; not much for a cross country flight. The landing gear was welded directly to the fuselage with no suspension. If built exactly to plans, the seat and interior width is only 19" wide. The fuselage and tail surfaces are fabric covered. There's a entry door on the right side. The nose was fiberglass.

Jerry originally designed the J3M to be fully enclosed, however when flown that way, positive directional stability was lacking. Jim Eich flew his J3M without full enclosure, and directional stability improved.

Jerry chose readily available four stroke Continental engines for his designs because during that time because the engines were easy to obtain, inexpensive on the surplus market, and quite reliable compared to the MAC engine.

I think this J3M is a good gyroplane project for someone who weighs less than 200 lb and thin enough to fit within a 19" cabin dimension.

Hi Guys,
I have some history with a Barnett J3. 3 guys in our club passed one around many years ago. The gear folded when the "pilot" dumped it at the PRA Convention in Rockford (late 1970's) and it now rests in pieces at the PRA Archimedes museum. This gyro has a great history and many funny stories center on it. Ask me some time.

The J-3 "body" is tube and fabric except for an ugly, blunt, very hinkey looking fiberglass nose piece. It is slab sided
If someone goes for it, I have a few 65-90 Continentals in various stages of life.

Tom,

Please share some of the funny stories that are associated with the PRA museum Barnett J3M. I'm interested!

We at the museum have been discussing rebuilding the gyro Tommy mentioned. I was told about the Barnett for sale. John - would they be willing to donate it. The donation would be tax deductible if that helps.
