Construx was another one of those erector-set type of toy that took more brains to operate than we had here at ilovethe80s.com. There were many things that could be made from a Construx set, and many of them had little electric motors that were used to power a rotor or propeller. There was another battery powered motor that was connected by wire to a control box that would allow you to move the Construx vehicle forwards or backwards. In reality, this was Fisher Price's version of powered Legos. Once you took apart one of the ships and put it in a box with another set, you basically had box of fake Legos.
