As a teenager, I used to read my coveted copy of American Aircraft Modeler from cover to cover every month, savor and desiring everything contained within its page. One item I really wanted was a set of Carl Goldberg Retractable Landing Gears, even if I didn't stand a chance of have a radio controlled airplane model to install them in anytime soon (to this day, I still have never had a model with retractable gear). Back in 1970s while at the Prince Georges Radio Control Club (PGRC) off of Rt. 3 in Maryland, the Patter ships all had either the Carl Goldberg or Rohm retracts. The Rohm type actuated with an unceremonious snap up or down, while Goldberg retracts, being servo actuated, had just enough of a transition time to make them über cool to watch (IMHO).
A few years ago, while collecting a few relics of my childhood whims, I bought a set of new in the box (NIB) "CG Retract Landing Gear." They can be used either with a tail dragger or tricycle gear airplane. The box has been on display in my hobby area. It is doubtful at this point that I will ever install them in a model.
