Sorrell Hiperbipe

The SNS-7 (Sorrell Negative Stagger, Model 7) was intended to give full unlimited aerobatic performance without sacrificing the comforts of a cabin-style aircraft.

The Sorrell family originated from the state of Oregon, which was the last state to ban homebuilt aircraft. Hobie Sorrell petitioned congress for experimental aircraft regulations, and his son Tim designed the Hiperbipe in a series of family designed homebuilt aircraft.{{cite journal|journal=Air Progress|date=October 1991|title=Hiperbipe|author=Budd Davison}} The design is of mixed construction. The fuselage, tail, engine mount, landing gear mounts, interplane struts and flight controls are all built from welded 4130 steel. The wings are made from wood, with wooden stressed skin. The landing gear is sprung steel tube. The engine cowling and wheel pants are fibreglass. The whole airframe is covered in doped aircraft fabric, including the plywood-covered wings. The airfoil is a custom symmetrical design.{{cite web|url = http://www.ae.illinois.edu/m-selig/ads/aircraft.html|title = The Incomplete Guide to Airfoil Usage|accessdate = 11 June 2010|last = Lednicer|first = David|authorlink = |date = March 2010|archive-date = 20 April 2010|archive-url = https://web.archive.org/web/20100420012244/http://www.ae.illinois.edu/m-selig/ads/aircraft.html|url-status = dead}}

The SNS-7 is capable of advanced aerobatics, including vertical eight point rolls and inside and outside vertical eights.

The tooling and manufacturing rights were acquired by Thunderbird Aviation in 2015, who began making parts and basic kits.{{Cite web|url = http://www.thunderbirdaviationmi.com/sns-7.html|title = Thunderbird Aviation|access-date = 20 April 2019|last = Jones|first = Ron}}

In April 2010 there were 22 Hiperbipes registered in the United States, two in Canada, and one in the United Kingdom.{{cite web|url = http://registry.faa.gov/aircraftinquiry/AcftRef_Results.aspx?Mfrtxt=&Modeltxt=HIPERBIPE&PageNo=1 |title = Make / Model Inquiry Results |accessdate = 19 April 2010|last = Federal Aviation Administration|authorlink = |date=April 2010}}{{cite web|url = http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp|title = Civil Aircraft Register|accessdate = 19 April 2010|last = Transport Canada|date = April 2010|url-status = dead|archiveurl = https://web.archive.org/web/20110718042755/http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp|archivedate = 18 July 2011}}{{cite web|url = http://www.caa.co.uk/application.aspx?catid=60&pagetype=65&appid=1&mode=detailnosummary&fullregmark=HIPE|title = GINFO|accessdate = 19 April 2010|last = Civil Aviation Authority (United Kingdom)|authorlink = |date=April 2010}}
