Remember to keep the model high enough to give yourself 
time to make corrections, but don’t let it get too far away. 
Otherwise, it will be diffi cult to detect its attitude and which 
way it is going.

One fi nal check before landing: see how the model will react 
when it’s time to land and you reduce the throttle. To do this, 
while still at altitude, cut the motor power. The model should 
establish a gentle, downward glide path. This is how the 
model will react when it’s actually time to land. Add power 
and climb back up to your original altitude.

Practice a few of these “climb and glides” to judge how far 
out you will need to be when it’s time to land.

If optional fl aps have been installed, slow the plane and lower 
the fl aps. Check to see if it climbs with fl aps. If it does, a 
small amount of down elevator can be mixed in.

Landing

To land, fl y down-wind past the landing area. Gently turn 

into the wind, and reduce the throttle so that the airplane 
initiates a descending glide path. If optional fl aps have been 
installed, lower them now. If necessary, add power to extend 
the glide path to reach the runway. As the model approaches 
and loses altitude, gradually and proportionally add “up” 
elevator to control the glide path and altitude. Continue to 
apply elevator until the model touches down at which time 

you should be holding full, or nearly full, up elevator. This will 

cause the airplane to slow and settle to the ground.

CAUTION:

 If, during a rough landing, the propeller be-

comes jammed and cannot rotate, the battery and speed 
control will become very hot if you attempt to add power. 
Immediately move the throttle down to stop the motor. If 
you fail to do this, the motor, speed control and/or battery 
will be damaged.

AFTER EACH FLIGHT

Disconnect the battery and remove it from the airplane. Then, 
turn off the transmitter. Allow the battery to cool before 
recharging, or allow the motor to cool before installing another 
battery for the next fl ight. Inspect the airplane to make sure 
nothing has become loose or damaged.

REPAIRING YOUR MODEL

If your model becomes damaged, it can be repaired using 
regular medium CA. Spare parts are available – please see 
the parts list earlier in this manual for more details of what is 
available and how to get new parts. CA debonder (GPMR6039) 
is available if you ever need to dissolve the CA adhesive you 
used to build or repair this model.

Have a ball! But always stay in control 

and fl y in a safe manner.

GOOD LUCK AND GREAT FLYING!
