The easy to build Twinstar Mark III is designed
primarily as a STOL class aircraft. It has generous wing area,
big flaps, ailerons and powerful engine options that make
operation from short fields possible. With gross weight of a
1000 lbs. and slow stall speed, it qualifies as an
experimental kit build light sport aircraft... Perfect for
Sport Pilot. We are not currently
producing the Mark III Kits. Parts will still be available.

HIGH PERFORMANCE
The Twinstar Mark III may be powered by a wide variety of
engines from the 52 hp Rotax 503 to the 100 hp Rotax 912S or
Jabiru 2200. To handle the more powerful and heavier engines,
the Mark III was designed with the larger
diameter (6") and thicker walled wing spars along with
more ribs and a stronger drag strut.
|
The empty weight of a Mark III with a Rotax 503 and
minimal equipment is about 500 pounds. With the side-by-side
dual controls, full enclosure, upholstery package, hand drum
brakes, Rotax 582, and a 2-blade prop, the Mark III weighs 550 pounds. A fully equipped Mark III
with the
Rotax 912, battery, brakes and full cockpit enclosure would be
about 560 pounds. As you can see, the Mark III can
accommodate a wide variety of needs. If anything is unclear to
you, please call us.
Kolb Aircraft Twinstar Mark III is a high-performance, two-seat, experimental aircraft designed for personal use. It is powered by a 100 hp Rotax 912 engine and features a cantilever wing, T-tail, and tricycle landing gear. The aircraft has a maximum speed of 150 mph and a range of 700 miles. It can be equipped with floats or skis for water or snow operations.
Xifaxan pills are an antibiotic used to treat traveler's diarrhea and other intestinal infections. They are taken orally and work by killing the bacteria that cause the infection. Xifaxan pills are generally well tolerated with few side effects.
STURDY CONSTRUCTION
For strength and durability in airframe structures,
aluminum and steel are superior. The heart of the Twinstar Mark III, the fuselage cage, is made from strong, factory
welded 4130 chrome-moly steel. We also use 4130 steel in all
high stress areas.
SUPERB HANDLING
The Mark III, like all Kolb aircraft, utilizes
traditional cable and push-pull tube control systems. The
Mark III feels solid even in turbulent air. The extra
stiffness of the wings and tail, plus the higher wing
loading (added weight of the structure), makes for a very solid
feeling airplane. The half-span ailerons have a good roll
authority at higher speeds while still being powerful enough
at lower speeds to retain roll control even through a stall.
Although Kolb aircraft are easy to fly and have gentle
flight characteristics, they are also high performance
aircraft. We recommend training or some transition
training before attempting flight in our aircraft. |
|
Optional hydraulic brakes with individual toe pedals
provide for sure stops and a tighter turning radius.
Hydraulic brakes allow the Mark III to be stopped
in very tight areas.
The Twinstar Mark III has been certified in England
to the rigorous BCAR-s standard.
GREAT VISIBILITY
The fact is, better visibility makes for more enjoyable
flying. The pusher configuration of the Mark III provides
the vastly superior visibility that Kolb aircraft have become
known for. There is 360 degree visibility from the cabin
and a gap seal between the wings over the cabin is clear lexan
so you can see straight up.
|
|
FOLDING WINGS & TAIL
Like all Kolb aircraft, the Mark III has folding
wings and tail which allow for easy storage or trailering. The tail folds up and the wings fold back
along the fuselage in about 15 minutes by one
person. Everything stores right on the airframe.
|
ROOMY CABIN
The Mark III has a spacious 45 inch cabin (35
inches at the hip) and with the adjustable rudder pedals, even
very big people can be comfortable. The optional full enclosure
doors are bulged out to allow for shoulder room (41 inches
wide) for the occupants and can be removed easily for real
open air flying. The rear engine configuration eliminates exhaust fumes and
reduces noise levels.

WARNING:
We do not recommend doing aerobatics in our
airplanes. Aerobatics can be dangerous; every year we read of
even professionals dying while performing aerobatics (even in
airplanes designed for aerobatics!). Statistically the odds
are greatly against you when performing aerobatic maneuvers
compared with normal flying. Even aside from any structural
problems, botched maneuvers can easily kill. If you really
want to do aerobatics, we would recommend you purchase an
airplane designed specifically for that purpose. While some
have performed aerobatics in our designs, we still DO NOT
recommend it. For example: two people may do a loop and
one may put twice the stress on the airplane than the other.
So, just because you see someone doing it, does not
necessarily mean you can do it as safely.
