f) The First Touch-Down
Reduce the motor speed and fly in wide and flat circles. Do not pull on the elevator too hard to reduce the flying
altitude slowly. Select the last curve before approaching for a landing so that you will touch down against the wind
and so that, in case of an emergency, you would have sufficient room for landing and so that you would not have to
make any considerable corrections to the course during the approach for a landing.
Always ensure sufficient flying speed and do not slow down the model by reducing the motor speed too much or by
pulling too hard at the elevator. It is only briefly before touch-down that the motor is stopped and the model lands
with the carefully applied elevator.
If you had to adjust the trim at the transmitter, correct the trim at the plane after touchdown (linkage wires for aileron,
rudder and elevator) so that the trim at the transmitter is in the middle position again and the model still flies straight;
see next section.
g) Trimming the Model after Touch-Down
The rods for the rudders should be set at the flight model so that the trims at the transmitter are in the middle positi
-
on. Thus, the entire trimming path for adjustment in flight is retained.
After the flight, remember the current trim position of every single rudder flap. Now set the trims at the transmitter
to the middle position with the model ready for operation. Then mechanically set the rudder linkages to match the
previous trim position.
For corrections of the rudders and elevators, open the service flap on the bottom of the fuselage. In figure 21, item
1, you can see the rudder servo, in item 2 the elevator servo. You can loosen the rods by loosening the respective
screw at the rod connection and then set them. Then the rods must be fastened in the desired position with the
screw.
