Sorrell Hiperbipe SNS-7 N777HT
Bill has been jonesing for a full-scale aerobatic plane for a while now.  He looked at a Christen Eagle and others, and kept coming back to this Hiperbipe that he first saw at an air show about 10 years ago.  It was absolutely mint at the time, and the 2nd owner kept it just as nice.  If you are not familiar with the Hiperbipe, here is a link with some history: The Mark Sorrell Company

Completed and test flown in 1982

Empty weight when built was 1289 lbs.  Some things have been removed since then.  A goal for 2004 is a new weight and balance.

See above..

Lycoming IO-360-C1C, 200 hp, fuel injected, inverted fuel and oil systems, airshow smoke system.

Hartzell, HC-C2YR-4CF, Constant Speed (variable pitch).

None, cross-over two into one system.  Sounds great!

100LL (100 octane, low lead).  Two fuel tanks, One 26 gallons and one 13 gallon aerobatic tank (flop tube equipped for inverted fuel feed).

King KY197 Communications radio, KY76 Transponder, Narco Blind Encoder (Mode C, altitude reporting).  For Navigation I have a Lowrance Airmap 500 GPS handheld and the view out the window.

Stay tuned, should be around 170-175 mph, cruise 160-165 mph, never exceed (VNE) is 225 mph,  stall is about 65 mph.  Final approach speeds used so far are 85-95 mph, still experimenting.

White with dark metallic green stripes.

The aircraft was initially owned by Hal Thomas of Oregon (later various locations in AZ).  The Sorrell brothers did a lot of the building and all of the test flying.  On their website www.sorrellco.com this aircraft is featured in the “Early Days” section.  The build quality is super.  N777HT is now about 22 years old and has about 730 flight hours, and while not perfect anymore, she still shows very well.  Paint and interior are original except for some minor paint touch ups here and there.

Fun, Fun, Fun.  Fast roll rate.  Nice climb rate.  My flight time at this point is minimal, my insurance company is requiring 10 hours dual instruction and I’m about  two thirds done with that.  Most of the flying to date has been either slow flight, stalls, minimum controllable airspeeds or pattern work (lots of touch and goes).  I intend to take aerobatic training in it later this spring.  Right now the WOW factor is still pretty high for me.  My previous experience is 300 hours in Cessnas, Tri-Pacers and, 26 hours in a Aeronca Champ.
