JETI model SPIN 11, Manual, Page: 7 / 10

By means of the push-buttons L-P we set the speed of balancing rpm deviations. The
smaller the number, the faster are the interventions. We always proceed from the higher
number. If a certain limit becomes exceeded the controller starts to operate unstable
(analogy with an overgyrated Model helicopter)
Motor timing (pre-ignition) – setting by means of push-buttons L-P.
Recommended values: 2pole motor...0-5°, 4p motor...0-10°, 6p motor..0-20°, 8p and
more...20-30° - necessary in case of the so called reversed motor conception
Motor control modulation frequency within the regulation range. Always use 8kHz. The
only exception are the so called iron free motors (Tango, Samba). For these motors a
frequency of 32 kHz must be used.
Speed of motor acceleration. On principle – the larger the propeller, the longer the
acceleration time value must be. For big reversed motors apply an acceleration time of 2
and more seconds. For model helicopters we recommend acceleration times of 5 and
more seconds.
Enter by means of the push-buttons L-P the type of flight
battery.
For NiCd/NiMh cells the min. voltage per cell is entered by push-
buttons L-P . For LiIon/LiPol batteries we can either enter the
automatic cell number recognition (comfortable if flying battery
sets with different cell numbers) or set the exact cell number.
Continue with push-button D and by means of. L-P set the min.
voltage per cell.
Information about the preset cut off voltage. With NiCd/NiMh cells or when setting the
automatic detection for LiIon/LiPol cells this value results of the actual voltage of the
connected flight batteries.
Mode of motor cut-off when the voltage of the flight batteries decreases to the preset
value. Slow Down – gradual decreasing of the motor power. Hard – immediate stop of
the motor. This mode we recommend for safety reasons on models with electric motors
and flight batteries of the NiCd or NiMh type.
