A new bomb release mechanism which allows an RC aircraft to carry an unlimited number of model bombs. The new bomb release mechanism allows the pilot to release these model bombs in any sequence using only one unused channel on the receiver in the aircraft. The present invention accomplishes these objectives by employing a special alloy metal wire which shrinks when subjected to an electric current. A programmed circuit is used to energize the metal wire upon receipt of the designated control signal.

Having described my invention, I claim: 1. A bomb release mechanism for releasing a model bomb from a radio-controlled aircraft, said radio-controlled aircraft having a receiver for receiving commands from a pilot on the ground, comprising: a. a holder configured to move between a first position in which said model bomb is securely attached to said bomb release mechanism and a second position in which said model bomb is released from said bomb release mechanism; b. a metal wire attached to said holder, said metal wire configured to shrink when subjected to an electric current and thereby move said holder from said first position to said second position when subjected to said electric current; c. a controller configured to supply said electric current to said metal wire upon receipt of a control signal. 2. The bomb release mechanism of claim 1, said metal wire comprising a nickel titanium alloy. 3. The bomb release mechanism of claim 1, said controller comprising a programmed circuit, said programmed circuit configured to count a quantity of bomb release control signals transmitted on a channel of said receiver and compare said quantity of bomb release control signals transmitted with a programmed value, said programmed circuit configured to supply said electric current to said metal wire when said quantity of bomb release control signals is equivalent to said programmed value. 4. The bomb release mechanism of claim 3, said programmed circuit having a switch configured to change said programmed value when actuated. 5. The bomb release mechanism of claim 1, said controller having a switch for assigning said controller a unique identity. 6. The bomb release mechanism of claim 1, wherein said controller is further configured to monitor a battery voltage for said radio-controlled aircraft. 7. The bomb release mechanism of claim 1, further comprising: a. a second holder configured to move between a third position in which a second model bomb is securely attached to said second holder and a second position in which said second model bomb is released from said second holder; b. a second metal wire attached to said second holder, said second metal wire configured to shrink when subjected to a second electric current and thereby move said second holder from said third position to said fourth position when subjected to said second electric current; c. a second controller configured to supply said second electric current to said second metal wire upon receipt of a second control signal. 8. The bomb release mechanism of claim 7, said second controller electrically connected to said first controller. 9. The bomb release mechanism of claim 8, wherein said controller and said second controller and independently programmable, wherein said controller and said second controller receive said control signal and said second control signal, and wherein said controller and said second controller each independently evaluate said control signal and said second control signal to determine whether an appropriate signal has been transmitted for releasing said model bomb or said second model bomb. 10. A bomb release mechanism for releasing a model bomb from a radio-controlled aircraft, said radio-controlled aircraft having a receiver for receiving commands from a pilot on the ground comprising: a. a holder configured to move between a first position in which said model bomb is securely attached to said bomb release mechanism and a second position in which said model bomb is released from said bomb release mechanism; b. a controller configured to actuate the movement of said holder from said first position to said second position; c. a programmed circuit configured to monitor a channel of said receiver for bomb release control signals, said programmed circuit configured to count a quantity of bomb release control signals transmitted on said channel of said receiver and compare said quantity of bomb release control signals transmitted with a programmed value, said programmed circuit configured to actuate the movement of said holder from said first position to said second position when said quantity of bomb release control signals is equivalent to said programmed value. 11. The bomb release mechanism of claim 10, further comprising a metal wire attached to said holder, said metal wire configured to shrink when subjected to an electric current and thereby move said holder from said first position to said second position when subjected to said electric current, and wherein said controller is configured to supply said electric current to said metal wire upon receiving said quantity of bomb release control signals equivalent to said programmed value. 12. The bomb release mechanism of claim 11, said metal wire comprising a nickel titanium alloy. 13. The bomb release mechanism of claim 10, said programmed circuit having a switch configured to change said programmed value when actuated. 14. The bomb release mechanism of claim 10, said controller having a switch for assigning said controller a unique identity. 15. The bomb release mechanism of claim 10, wherein said controller is further configured to monitor a battery voltage for said radio-controlled aircraft. 16. The bomb release mechanism of claim 10, further comprising: a. a second holder configured to move between a third position in which a second model bomb is securely attached to said second holder and a fourth position in which said second model bomb is released from said second holder; b. a second controller configured to actuate the movement of said second holder from said third position to said fourth position; c. a second programmed circuit configured to monitor said channel of said receiver for bomb release control signals, said programmed circuit configured to count said quantity of bomb release control signals transmitted on said channel of said receiver and compare said quantity of bomb release control signals transmitted with a second programmed value, said second programmed circuit configured to actuate the movement of said second holder from said third position to said fourth position when said quantity of bomb release control signals is equivalent to said second programmed value. 17. The bomb release mechanism of claim 16, said second controller electrically connected to said first controller. 18. The bomb release mechanism of claim 16, wherein said controller and said second controller and independently programmable and wherein said controller and said second controller each independently determine whether an appropriate signal has been transmitted for releasing said model bomb or said second model bomb.
