What ever happened to the Sorrell SNS-7 Hyperbipe?

I've been looking for a set of plans for several years, and no one really knows what to make of it's disappearance. I do recall a dispute many years ago but I'm not sure if it was in regards to the plans.

Anyone know of a set for sale or someone who may have a set they're willing to part with?

Dave,

There is an active Hiperbipe group on yahoo, you might check that out.  One thing is that the HB was only available as a kit so there was never a complete set of plans.  Tthere weren't any plans for the wings, the wings were available either closed or with one skin not installed so detailed plans of the wings weren't needed.  It is however a great plane.

My dad once owned a Hiperbipe.  It is truly a unique aircraft.  Very capable and comfortable.  Unfortunately, the original builder didn't varnish the wings and they rotted to beyond repair while it sat during his illness.

The story I've heard was that some attorney wanted a Hiperbipe and decided he wanted Mark's personal Hiperbipe.  Although it wasn't for sale, he started counting money till he got to a point that Mark couldn't refuse.  On a subsequent flight, the new owner ran the tanks dry in the traffic pattern and landed short of the runway on the rocks destroying the plane.  Being an attorney, he then decided it couldn't have been his fault and then sued Mark.  Although Mark won, he was so disgusted w/ the process that he quit selling kits.

I have a set of plans...somewhere.

Thanks for the replies guys. I was able to find the Yahoo thread and will see what's available.

Here's the thread if anyone else is interested.

Thanks, Dave.

I have a Hiperbipe SNS-7 that I would concider selling. The plane has just been recovered and fresh out of the paint shop. Also I have an AEIO-360 with a c/s prop that just came out of the prop shop with an inspection, reseal, dressed and painted. You can email me at jpaulthepilot@gmail.com if you are interested.

 

Thanks,

Jason

MVC-004F.JPGHi Dave;

As far as I can tell there were 53 flying Hiperbipes in the world as of January 2010. Unfortuntly we lost one about a month ago in a fire...

As stated above the HB was never offered as a real "plans-built" airplane...you recieved the 4 wings, all wood and built like an R/C airplane wing; wood spars, wood ribs and plywood sheeting on the bottom surface all ready for inspection and "closing up" by the builder. The fuselage was delivered with the left and right sides welded together to form the airfoil shape but you had to fabricate and weld all the rest of the tubing...and there is a LOT of tubing! Add to that the nessessary fabrication of the alieron/flap mixer (a whole lota parts) as well as the whole rest of the airplane and you had a job in front of you that might span 3000 man-hours or more.

In 1977 an airplane called the Christen Eagle came out with a kit that included a pre-welded fuselage and tail group, built wings (ready for cover), pre-fabbed everything and a build time advertised at 1200 hours total.

For the Hiperbipe; the timing was simply lousy.

 

I own 7HT; a Hiperbipe built in the 1970-80's and with a lot of "Factory Love" lavished on it. It is a comfy cross-country criuser (160mph is my flightplan) and will pull +6/-4 acro all day long!  Vne is 225 mph. The cabin is 47" wide, the whole front and top is plexiglas and the negetive stagger of the wings make it  a not-too-bad biplane visiblity-wise. The best feature (in my humble opinion) is the fuel tank set-up...instead of the normal header tank setup where you burn your 2-3 gallons and then have to roll back over to replensh the tank the HB has a main tank of 29 gallons and a acro tank with 13 gallons...I can roll on my back, trim for level flight and criuse for over an hour upside down on the acro tank...

I'm the mod on the Hiperbipe site on Yahoo.  Knock on the door and I'll let ya' in.

Do you know where you could get a real good 3 view of the Hyperbipe? I’ve looked for HB construction web sites but not found any.

 

Thanks,
