Problem Statement
RC has all the pieces and worked once but then did not anymore.

Designing the Implementation Process
The Futaba RC T4YF is a remote control with 4 channels(channels are the number of controls that the remote can send to the receiver). It requires a 12V wall charger and takes about overnight to be fully charged.

The Rc and the receiver must have a 75MHz crystal which is already in place. To find these just pull the little cap that say 75MHz.(one in the RC and another one in the receiver)

The servos can be placed in any of the first 4 channels since it is a 4 channel RC, and then each channel has a function:

When the aileron stick is moved to the right, the right aileron is raised and the left aileron is lowered, relative to the direction of flight, and the plane turns to the right. When the aileron stick is moved to the left, the ailerons move in the opposite direction. To level the plane, the aileron stick must be moved in the opposite direction. When the aileron stick is tilted and held, the plane will roll. When the elevator stick is pulled back, the tail elevator is raised and the tail of the plane is forced down, the air flow applied to the wings is changed, the lifting force is increased, and the plane climbs (UP operation). When the elevator stick is pushed forward, the elevator is lowered, the tail of the plane is forced up, the air flow applied to the wings is changed, the lifting force is decreased, and the plane dives (DOWN operation). When the throttle stick is pulled back, the engine throttle lever arm moves to the SLOW (low speed) side. When the throttle stick is pushed forward, the throttle lever arm moves to the HIGH (high speed) side. When the rudder stick is moved to the right, the rudder moves to the right and the nose points to the right, relative to the direction of flight. When the rudder stick is moved to the left, the rudder moves to the left and the nose points to the left and the direction of travel of the plane changes.

 * Channel 2:ELEVATOR OPERATION
 * Channel 3:THROTTLE OPERATION
 * Channel 4:RUDDER OPERATION

Test, Verification, Validation, and Certification
All pieces are in the right place and it worked for once.
 * 1) Possible problems:
 * Servos on test might not be working
 * Crystals have been on remote and receiver for an unknown time and might be damaged

Next Steps

 * Go to a Hobby shop,(the one in Crofton is the closest one specialized in Futaba products) check for crystals and test the ones in use.
 * Test more servos available at school.
 * Try to make a 6V charger for the receiver battery with material available at school.
