I bought the following recently from flite test recently as a stem project for my 10yr old son. He did a great job putting the model together but he made a mistake when pairing the transmitter with the controller now we are unable to get the, to talk to each other. How can we factory reset or pair the transmitter and controller once again? I have included the parts list so someone. An help or guide us
