The Valmet PIK-23 Towmaster or Suhinu is a Finnish two-seater glider-towing/primary trainer aircraft built entirely out of composite materials in the early 1980s.
The Finnish technology students aviation club (PIK) suggested in the 1970s, that a new aircraft should be developed for glider towing. The work focused on the improvement of a previous design, the PIK-19 Muhinu. Later on, the Helsinki University of Technology and Valmet Oy joined the project and the design process started from scratch. The goal was to develop a target/glider tower, which also could be used for basic training. It was given the name "PIK-23 Towmaster".
Only two aircraft were manufactured, one at Valmet and one at the Helsinki University of Technology. The first aircraft, OH-TOW, made its maiden flight on March 22, 1982, flown by Mikko Järvi. The second aircraft, OH-TUG, flew the following year.
Valmet marketed the aircraft intensively, but no orders followed. It was also investigated if the aircraft could be sold in parts, for self-assembly, in order to lower the price. In its intended role as a glider tower, the PIK-23 has been quite successful.

This new wing had a span of 20 metres, featuring interconnected ailerons and flaps, Schempp-Hirth-type airbrakes. It had no provision for water ballast. The monowheel undercarriage differed from the IS-28 in being fully retractable.

The PIK-3 was a sailplane produced in Finland in the 1950s and 60s. It was designed to be a cheap and easy-to-build aircraft to equip the country's gliding clubs as their standard single-seat machine. It was a conventional design for its day, with a high wing and conventional empennage. Construction was of wood throughout, skinned in plywood.

The PIK-15 Hinu is a light aircraft developed in Finland in the 1960s for use as a glider tug. It was a low-wing cantilever monoplane of conventional design with an enclosed cockpit and fixed, tailwheel undercarriage. The cockpit had two seats, side-by-side, and the PIK-15 was intended to have a secondary role as a trainer. Construction was of wood throughout.
The PIK-19 Muhinu was a light aircraft developed in Finland in the early 1970s for use as a glider tug and flight trainer. It was a low-wing cantilever monoplane of conventional configuration, with an enclosed cockpit and fixed, tricycle undercarriage. Its construction was of composite materials throughout, a novel approach at the time. When the PIK-19 flew for the first time in 1972, it was only the fourth aircraft in the world made of these materials.
