OK, let's settle this thing once and for all ;^)
I dug this kit out from the boxes in my basement and here's the scoop.
Revell H-801 1978 Coast Guard Rescue Chopper LIGHTS! ACTION! SOUND! Electronic Action Kits
This kit is a Coast Guard UH-1(H?) s/n (b/n?) 61036, molded in white with day-glow orange stripes. All markings are waterslide decals except for two day-glow orange main rotor tip stripes which are stickers. These stickers hold glow-in-the-dark, soft plastic tips onto the main rotor for (presumed) safety reasons. This is a glue kit, with some snap-together parts, that is a simplified version of Revell's previously released 1/32 UH-1D (actually a UH-1H) Huey. By simplified, I mean all doors are now an integral part of the fuselage instead of being separate and such. The kit includes a motorized main rotor, which as near as I can tell, also produces the advertised engine whine sound through gearing connecting the electric motor and the rotor drive shaft. There is a green light for a "radar" scope in the instrument panel, a cabin light in the overhead instrument panel, a single light in the engine exhaust which also shines through a beacon light on top of the aft engine housing, and a red LED light in the trailing edge of the lower tail. The cabin lights dimmed as the motor speed was increased causing the engine exhaust light to glow brighter. The whole operation was set into motion by turning the tail skid. This tail skid operated a variable resistor so the rotor speed could be varied. The kit box lists the feature "As the motor revs, chopper rocks" apparently taking advantage of the natural imbalance of the whole assembled model. Two "C" batteries powered the whole thing.
I don't recall what this kit originally sold for but I know I got mine for a heavily discounted price when it went out of production around
Hope this sheds some light on a little-known and long forgotten kit.
