Charge the receiver battery.
Make sure there are no other pilots operating on on the same channel  (frequency) as you are.  If you turn your 

radio on while he is flying, you will cause him to crash.

Check you radio for good range (50 ft. with the antenna collapsed) and proper operation.

2. Take-off

A proper hand-launch of the airplane is necessary for flight.  It must be launched into the wind with a firm 

toss.  The airplane must be tossed level or even pointed a little down.  It should never be thrown upward, or it 

will stall and crash.

3. Flight

Steer very gently right and left to keep the wings level.  Let the airplane climb out gradually and gently until it 

reaches a comfortable cruise altitude at full flight speed.  Always keep the aiplane upwind of yourself and within 

a reasonable distance so you can see what it is doing.  Remember, when the plane is coming toward you, when 

you move the stick to the right, the aiplane will go to the left from your point of view.  This is the hardest thing 

to learn.  Initially, you can keep your body pointed in the same direction as the airplane and look over your 

shoulder.  That helps.

Usually, only small stick movements are required.  Try to keep your flying smooth.  You can turn the plane by 

bumping small amounts of rudder and then return to neutral.  Use the elevator to keep the airplane at the desired 

altitude.  After awhile, coordinate your turns with the elevator; i.e., bank the plane with a little bit of rudder, then 

feed in some up elevator to maintain the turn at the same altitude.

If the plane tends to turn one way or the other use the trim lever on the control stick to neutralize the flight.  Same 

thing applies if the place wants to climb or dive.

You can expect 3-4 minutes of “power-on” flight.  You should always maintain enough altitude so you can set up a 

landing approach when the auto-cut off device turns the motor off and you begin the glide.

4. Landing

When the motor cuts-off, set up your landing approach.  Always try to land INTO THE WIND.  Keep your turns 

gradual and only use elevator to maintain a gradual glide.  Since the motor is off, you can no longer climb and the 

plane slows down.  If you feed in too much up elevator, the plane will stall and may crash.

Just before touchdown, “flare” the plane by adding up elevator.  The plane should slow down even more and come 

in for a gentle landing.  Don’t add too much elevator, too soon!

Walk over to the plane and turn off the switch on the plane, then the transmitter switch. 

Remove the batteries and let thme cool off before charging up again.

Check over the plane to make sure nothing loosened up or broken.

V.  IN CASE OF TROUBLE

If your motor does not run when the start button is pushed, make sure the 10 Amp fuse on the Auto-Cutoff device 

is OK and that the batteries are properly charged.

If the radio is erratic (glitches), check that the transmitter and receiver antennas are extended to their full length.  

Make sure the transmitter batteries are fresh.  Make sure no one else is operating on your channel (frequency) in 

the immediate vicinity.  

If the plane does not fly properly, make sure you are being gentle with the control inputs.  Make sure the plane is 

balanced properly (Fig. 4).  Make sure all the wing and tail surfaces are flat, true, and properly attached and aligned.  

If your trouble persists, call 660-584-6724 for technical help.

VI. CONCLUSION

To defeat the laws of gravity and take to the wing is both challenging and thrilling.  We hope you enjoy your entry 

into the fascinating world of R/C flight and make it your hobby for a lifetime.  Please let ACE R/C be your chosen 

brand, no matter what direction you progress.
