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.
