Challenger 11
The Challenger 11, first introduced in 1984 is a tandem seating two place, pusher in a
trigear configuration. The craft uses bolt and rivet together construction covered in
either dacron sail cloth or conventional aircraft covering materials. Buildingtimes
vary depending on the type of covering materials used.

For the standard kit using dacron sail
cloth 100 hours is a realistic building time, kit construction almost doubles when
standard fabric covering is used.
The design has been flying since 1984 and was one of the
first true three axis control two place trainers on the market. There are reported to be
nearly 200 flying in Canada.

A T.U.F. VIEW
The Challenger 11 can be powered by 447 and 503 Rotax. The engine sits upside down at the
rear of the craft and uses a belt reduction drive system. My preference would be to fly on
the 503 Rotax. With this engine cruise comes in at 65 m.p.h. at 5800 RPM climb rate at
gross as a land plane is around 850 feet per minute. Stall with the aid of flaperons 35
m.p.h.
The factory rates an A. Control feel is a little mushy, and requires pilot input
to compensate for adverse yaw. Landing gear is another weak point. Great little plane for
pilot with limited budget, not recommended for rough field operations,
or busy flight schools.
