SONICON ROCKET - MASUDAYA - JAPANTin battery operated remote control rocket advances as antenna turns. Direction controlled by whistle. Complete with two boxed whistles and spare antenna. MT. Two litho versions of this rocket exist: blue/light blue version (top) and the blue/silver patterned version. (bottom)

The mechanism works as follows: an air chamber with an opening and a diaphram above the opening with a conductor across two contacts. When the whistle blows the air in the chamber resonates causing the diaphram to vibrate and open the connection between the contacts which switches a relay causing the wheel assembly to spin in circles until the whistle stops and the ship heads off in whatever new direction the wheels are heading.

On sale in December 1960.
Appears in the Mail Order Gift Catalog for 1961.
