Congratulations on your purchase—and thank you for choosing our Tower Hobbies
hours of trouble-free flying with it, because it includes all the features we knew you'd want in a solid, sensible flight system.
The 4FM offers four-channel control, the magic number for many sport and competition planes. As an FM (Frequency Modulated) narrow-
band system, it's far less vulnerable to interference than AM radios. The narrow-band transmitter and dual-conversion receiver enhance strong
control by filtering and boosting the signal. Put them together, and you have a radio that can provide smooth, glitch-free control even in today's
"noisiest" radio environments.
Those are big pluses, but we went the extra mile to make the 4FM the most versatile and easy-to-use radio we've ever offered. The case is
designed for a firm, comfortable "hand feel." Pick it up, and levers, sticks and switches almost seem to move to meet your hand. That includes the
switch for the built-in trainer system—an extra that can help you learn from other flyers, or help others "learn the ropes."
We also included rechargeable, NiCd batteries and a charger, a convenience that saves you time and money. And we made sure that the
4FM was compatible with all Tower Hobbies System 2000
to 1/4 scale.
Solid value, ease of use, versatility—the 4FM offers it all, plus a 1-year limited warranty, the ultimate in protection for your radio investment.
Again, congratulations on your purchase—and happy flying!

entire manual before operating your System 3000 R/C system.
1. Charge the transmitter and receiver batteries for 15 hours with the included charger.
2. Connect servos, 4-cell battery pack and switch harness as shown above.
3. Turn on the transmitter, then turn on the receiver switch harness.
4. Center all four transmitter trim levers. Make sure all servos operate according to transmitter stick movements.
5. Turn off the system, receiver first, then transmitter.
6. Wrap the receiver and receiver battery in
7. Install the entire radio system into your model as shown in the model's instruction manual (see above for proper channel usage).
8. If you need to reverse the direction in which a servo rotates, locate the servo reversing switch for that particular channel on the bottom of
the transmitter and slide it to the "REV" position.
9. Range test the radio system prior to flight. With the transmitter antenna collapsed, you should be able to smoothly control movement of all
control surfaces on your model from at least 100 ft. on the ground. If not, refer to the Troubleshooting Guide on page 7 for directions.
