This small helicopter, released in 1990, was the smallest to date at the time.  It features rotating main and tail rotors.  The canopy is constructed from liftarms and links.  The liftarms lock at 90 degree angles, while the links are pinned.

While this set features a minifig seat the cabin is to small for a minifig unfortunately. I expect when a minifig will try to flu it anyway it might work that the head stays under the rotor. However when taking of I am afraid his head will be sucked into rotor anyway!

This is the only Technic set released this year which does not have wheels, and remains one of the very few such to this day.

This particular little model looks vaguely like a Robinson R22.

 

 

Main model

Features

Rotors

The rotors' rotation is driven by an input crank on the left side. This crank drives a set of 8 and 24 tooth gears. The 8 tooth gear drives the main rotor. The 24 tooth crown gear meshes with a second 8 tooth spur which runs back to a set of 14 tooth bevel gears on the tail rotor. Both main and tail rotors turn at the same rate, with a ratio of 3:1 with respect to the input crank The main and tail rotors each have 2 blades and use the specialized 2 blade rotor part for this purpose.

Skids

The landing skids are constructed from beams and supported by liftarms.
