Uniquely capable Hiperbipe airframe for sale. Price reduced for quick sale to a good home!!

Fully aerobatic to +6 and -3 G, fitted with a full Christen inverted fuel and oil system, this excellent aeroplane is great for touring or could make an great airshow act for 2025! Built in 1980 and with only 1110Hrs, this aircraft is still young and enthusiastic!!

The airframe was modified in 2011 (with full LAA approval) to add structural hardpoints aft of the cockpit for fitting experimental sensor research installations externally.

Since then, we ve created some unique data and results. You can read the story about this machine in Light Aviation, Feb 2022 (see link below!).

After 14 years of experimental work, we ve decided to call it a day.

We dismantled our airworthy aircraft at Annual inspection in June this year to fix the present squawks and start the process of returning it to stock configuration.

However, it s now behind other more urgent projects requiring completion.

Consequently and reluctantly, we re offering this complete airframe for sale to someone with the time, energy and sense of adventure to put this amazing machine back in the air. All components are there, the finish is in excellent condition, and the squawk list is simple to fix we just don t have the time to do it!

Bolt on the engine and propellor of your choice, fit the instrument panel of your dreams and have (currently) the only Hiperbipe flying outside North America!

Previous IO-360 B1E Engine (625 Hrs since O/H) and Hartzell HC-C2YR-4CF propellor (31 hrs since O/H) available by separate negotiation if required.

Can be seen at Kemble.
