ADJUSTMENTS AND FLIGHT TECHNIQUES
•BFS (BATTERY FAIL SAFE) AND BFS MEMORY
•BFS (Battery Fail Safe) is a warning function
which moves only the throttle servo to the same
position as set for FS when there is only a small
amount of power left in the receiver Nicd bat-
teries. (If no FS position is set, the throttle servo
is moved to medium slow.)
•When BFS occurs, the throttle servo can be re-
leased and throttle control regained for 36
seconds by lowering the throttle lever to IDLE.
• The throttle lever position at which throttle con-
trol is regained is programmable. This is known
as BFS Memory and is set as follows:
1 Set Function Select Switch 49 to BFS MEMO
SET and set Channel Select Switch 48 to Pos.
3 (Throttle).
2 Set the Throttle lever to the desired release
point (between Slow and Medium Slow recom-
mended) and press Buttons 46 and 47 simul-
taneously. BFS Memory is now set.
3 Set Switches 48 and 49 to OFF.
4 Whenever BFS occurs in flight, lower the throt-
tle lever to regain control and immediately land
the aircraft.
•SERVO TEST FUNCTIONS
•The operation of the servos can be checked by
setting the transmitter and receiver power
switches to ON.
•The servo test is started by pressing button 46
and is stopped by pressing button .47].
•When switch 49 is switched to TEST-A, the
servos move half-side first and then, come back
to neutral and repeat the other-half from chan-
nel 1 to channel 8. (Channel select switch (R)
48 to TEST-ALL position at this time.) The
servos set by the channel select switch do not
operate. (If set to 5, the landing gear servo does
not operate.)
•When switch 49 is switch to TEST-B, all the
servos operate linearly over their full travel.
(Channel select switch (R) 48 in TEST-ALL
position at this time.) Only the servos set at the
channel select switch are operated.
