The fin unit for the #1978 Gemini Titan kit was also used for the MX Missile kit and the Titan II Missile kit. The twin engine bells from the Titan II kit were used for the GT kit for display as well. The MX missile kit had a single-bell display nozzle and was unique to that kit.

The clear plastic fin unit used in these three kits is WOEFULLY fragile and is known to snap fins at the root. If you build any of these three kits, PITCH into the TRASH the dismally inadequate 12" chute and replace with a quality 18" chute. If you do not, fins WILL break on anything but the gentlest of landings in no wind on soft ground.

Makes one wonder who decided chute sizes at Estes...those three kits all weigh more than DOUBLE the weight of a Cherokee-D, which Estes RETARDEDLY decided needed a 18" chute where a 12" is almost overkill.

Incidentally, Estes later molded this same twist-lok fin unit in black for some other later kit that I cannot recall.
