Sonerai 2
The Sonerai II (original) is one of the most
versatile two place homebuilt aircraft ever conceived. In its
original form, the standard Sonerai II is a mid-wing, two place
tandem aircraft, that is flown from the rear seat solo. The II-L is
the same aircraft but with a "low-wing". The low-wing version is
especially popular with 6 foot plus pilots, as the pilot legs go
over the main spar carry through structure. The Sonerai II-LT
(Low-wing, tri-gear) is the same as the Sonerai II-L, but has a
steerable nosewheel added to the structure. Many builders with
limited or no taildragger experience opt for the tri-gear addition.
All models of the Sonerai II use a minimum of different sizes of
materials to reduce the cost, without hampering the integrity of the
design. The wing is all aluminium and is composed of two panels that
easily fold along side the fuselage enabling the Sonerai II, II-L
and II-LT to be towed tail first on its own gear. Stainless steel
cherry rivets are used to skin the wing. The fuselage and tail
surfaces are constructed of standard sizes of 4130 steel tubing that
are fabric covered. All aluminium sheet used is 2024-T3 .025" except
for the spars which are .040".
The fibreglass cowling removes easily to allow complete access to
the engine, magneto, tank and instruments. The landing gear is a
formed aluminium spring with 5" wheels and 3/4" axles. A tapered
tailspring rod is used for the tailwheel (II and II-L) All Sonerai
II's feature a l0 gallon main tank with the option of a 6 gallon
auxiliary tank carried on the passengers floor board (w/out
passenger).
The Sonerai II, II-L and II-LT are an excellent choice for the
individual who desires a high performance, two place VW powered
sport aircraft. The Sonerai II series will accept VW powered plants
in size from 1700cc - 2180cc.
