I got this set with missing parts and no instructions from a free CraigsList ad. Free is what I recommend spending for this set if it is incomplete, as it only has 17 pieces. You probably already have most of the parts to build this thing, besides the weird, non-technic propeller mount.

It looks like all tiny sets from the era: blocky but endearing. The weight of the 4 1x8 plates gives the propeller quite a bit of inertia, so it spins very nicely.

I spent more time writing this review than I spent building the set. It will get disassembled after I post this review. This is 17 LEGOs and a piece of paper that came free with a dirt-cheap meal in 1989. The only thing better than LEGOs is free LEGOs. Five stars.
