Shaking down my 1980 SNS7 Sorrell HiperBipe “MAKO” to see how it compares to the original numbers published in the POH. MAKO packs a punch with an angle valve high compression 9.5:1 IO360 C1C fully inverted 225 hp Lycoming. We rebuilt the airplane in 2020. Engine, prop, avionics, interior, paint and graphics. 1st flight since restoration was 92221. After 110 hr of flight time this year we decided to make this video on the performance specs. Hope this answers some of your HiperBipe questions.
