Modular toy aircraft

A toy aircraft, comprising:

• an airframe;
• and
• a self-contained modular power and control system configured to be optionally used with and used separated from the airframe, comprising:
• a propulsion unit operable to propel the toy aircraft;
• and
• a power and control unit, wherein the power and control unit comprises at least one energy source, is electrically connected to the propulsion unit, and is configured to control operation of the propulsion unit to control flight of the toy aircraft;
• the airframe comprising:
• a wing, wherein the wing comprises an extruded polystyrene foam panel and the wing is at least partially frictionally retained relative to the fuselage;
• a propulsion unit mount configured to removably retain the propulsion unit;
• and
• a power and control unit mount configured to removably retain the power and control unit;
• and
• wherein the toy aircraft further comprises at least one molded plastic clip configured to at least partially retain the wing in a predetermined position relative to the fuselage.

A modular toy aircraft, comprising:

• an airframe, comprising:
• a fuselage having first and second sides;
• a wing connected to the fuselage, the wing including first and second portions extending from the respective first and second sides of the fuselage;
• a first motor unit mount disposed on the first portion of the wing;
• a second motor unit mount disposed on the second portion of the wing;
• and
• a power unit mount disposed on the fuselage;
• and
• a modular power system configured to be optionally used with and used separated from the airframe, comprising:
• a first motor unit;
• a first propeller driven by the first motor unit;
• a second motor unit;
• a second propeller driven by the second motor unit;
• a power unit, comprising:
• a battery;
• and
• a control circuit electrically connected to the battery and to at least one of the first and second motor units, wherein the control circuit is configured to control flight of the modular toy aircraft by regulating energy supplied from the battery to at least one of the first and second motor units;
• wherein the first motor unit mount is configured to removably receive the first motor unit in at least one first predetermined orientation relative to the wing;
• wherein the second motor unit mount is configured to removably receive the second motor unit in at least one second predetermined orientation relative to the wing;
• and
• wherein the power unit mount is configured to removably retain the power unit in a third predetermined orientation relative to the fuselage.

A modular power system for a toy aircraft, the modular power system comprising:

• a first motor unit, comprising:
• a first housing;
• a first motor disposed within the first housing;
• and
• a first propeller driven by the first motor;
• a second motor unit, comprising:
• a second housing;
• a second motor disposed within the second housing;
• and
• a second propeller driven by the second motor;
• and
• a power unit, comprising:
• a third housing;
• a battery disposed within the third housing;
• and
• a control circuit disposed within the third housing, wherein the control circuit is electrically connected to the battery and to at least one of the first and second motors, and the control circuit is configured to control operation of the at least one of the first and second motors by regulating current supplied from the battery to the at least one of the first and second motors;
• and
• wherein the modular power system is configured to be optionally separated from and used apart from the toy aircraft, and the control circuit remains electrically connected to both the battery and at least one of the first and second motors while the power unit and the first and second motor units of the modular power system are being separated from the toy aircraft.
