FMS Fox - First Touch-Down Procedure; Post-Flight Trimming Adjustments

53
e) The First Touch-Down
Fly large, at circles with the motor on. Do not pull on the elevator too hard to reduce the ying 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 sufcient 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 sufcient ying speed and do not slow down the model by reducing the ight speed too much (e.g.
by pulling too hard at the elevator). The model is only brought down with careful application of the elevator briey
before touchdown. If you have programmed a „Buttery“ computer radio remote control, you can land precisely with
careful control of this function.
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 ies straight;
see next section.
f) Trimming the Model after Touch-Down
The rods for the rudders should be set at the ight model so that the trims at the transmitter are in the middle positi-
on. Thus, the entire trimming path for adjustment in ight is retained.
After the ight, remember the current trim position of every single rudder ap. 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.
