The "8" was painted on the fuselage to appear like an "S", thus "SOAR". In the USA
several modifications were made including a steerable tail wheel and sprung wing tip
wheels so that the aircraft could be taxied around. Also an electric starter motor was
added and an
electic fuel pump to help make the engine more reliable. A new fibreglass "Scimitar"
propellor was fitted to improve climb performance. Later when the aircraft was
repainted the owner sprayed the wings and fuselage with a polyester filler and profiled
the wings. It was claimed
that the performance was improved to be similar to a standard Cirrus. However the
flying weight of the aircraft was now 415kg, some 30kg heavier than original.
The aircraft was sold in Nov 1988 and went to New Zealand where it was registered as
ZK-GOT. In order to obtain a certificate of airworthiness the flying speeds had to be
reduced because of the excessive weight. Also after a number of years the engine
pylon cracked and had to be replaced. This was because of the fibreglass propellor
which was nearly twice as heavy as a wooden one.
In Feb 1999 the aircraft was shipped to Australia to become VH-ZOT. Again the
excessive weight proved to be a problem and the fibreglass propellor and electric start
(and large battery) had to be removed in order for the aircraft to obtain a certificate of
airworthiness. After only a few flights the original Hirth engine developed a crankcase
leak
which caused oil to cover the points and stop the engine. It was decided to replace the
engine and refurbish the aircraft. The polyester filler was removed from the fuselage
and wings, saving some 20kg of weight. A new MZ201 dual ignition, twin cylinder two-
stroke was fitted and a solar panel was added to keep the battery charged when
soaring. The aircraft has now been flown a few times with the new engine and it
appears to be very good. Hopefully it will see a lot more soaring in the near future.
