I remember having a Tamiya Apollo CSM/LM kit with a twist: It was
MOTORIZED. There was a propeller (clear plastic) protruding from the
Service Propulsion System engine bell and there was a swivel mount that
looked like a bit of lunar surface that you secured to the ceiling with
thumbtacks and double-stick foam tape. The CSM could be suspended by
itself, or with the LM "docked." There were multiple balance points on
the SM for this. You would attach a small hook into the balance point,
suspending the craft about 3 feet from the ceiling. A switch on the
command module started the engine and the the whole thing would begin to
"orbit" faster and faster, in increasingly larger circles until it was
really traveling, about a foot from the ceiling! It was fascinating, but
scary to be standing under. It was a nice kit, molded in black and white,
but this version was mostly a toy.
The CM comes with an electric motor and a propeller that you can install in the rocket engine housing. You can then attach the kit to the ceiling via some fishing line and get it to "orbit"! The LM comes with a very realistic moon rock/lunar surface base.
This may make them sound a bit toyish and quite unusual for TAMIYA, but don't let it put you off - they're great kits. However, It took me years to find them and they're not cheap.......
