Sorrell Bathtub

Built by Otto Sorrell circa 1950, the Sorrell Bathtub was a single-place, open cockpit, high wing monoplane, inspired by 1924 Dormoy Bathtub.

An “ultra-ultralight” powered by a geared-down chain-saw motor and tricycle gear, it was further developed by Michael Kimbrel, of Oakville WA, who in 1978 flew a tail-wheel version with a VW engine, then promptly sold 400 sets of drawings to home-builders.

The single-seat aircraft received an Airworthiness Certificate on 26 May 1964.

It was later registered to Wild Blue Aero Squadron LLC, Indianapolis, IN, USA.

Sorrell Triplane

The 1957 Sorrell Triplane N6441C is a three-quarter scale replica of the WW1 Fokker triplane. Painted red, with silver rudder and white lettering, the single-seat Sorrell Triplane has a span of approximately 17 ft. 8 in., and is powered by a 65-hp Continental A65 flat-four.

The owner-constructor flew it from a private airstrip at Rochester (Washington State).

Sorrell Biggy Rat

Satisfied with the lightweights, the Sorrells in 1967 constructed a sturdier negative-stagger single-place biplane powered with a converted 125 hp GPU by Lycoming. It had a streamlined fuselage profile with the windshield fairing right down to the spinner and no tapering of the side frames at the tail. Unusual was the method of mounting up – lift the rear portion of the skylight, climb up on top of the fuselage and slide down into the single seat.

Registered N3717 and named “Biggy Rat” by a younger Sorrell with an artistic bent, with the 125 hp and a very thin (10%) airfoil, “Biggy Rat” could cruise at 130 mph indicated – and could still operate with relative ease out of their 900 ft. cul-de-sac airport.

With a beefier structure and adequate power, John and Mark were able to indulge themselves in some aerobatics. “Biggy Rat” is very light on the controls – even touchy – and has done with ease all that has been asked of it in its 160+ hours of flying time.
