"Radio control problems are fairly infrequent in this day and age of reliable electronics. Failing to change batteries account for the vast majority of R/C problems." - Tamiya

"Arrange the radio wiring, to switch and servos, in a neat logical arrangement, with no pressures on the connections. Always protect these electronics from moisture and dirt, using rubber bags or sealed compartments. Keep your receiver antenna wire clear from moving parts."

1. Are the switches on?
2. Are the batteries inserted correctly and making contact?
3. Do transmitter and receiver crystals have the same frequency?
4. Are the connectors hooked up properly?
5. Are the servos and moving parts free or entangled with wiring?
