Controllers SPIN
1

Dear friends,
herewith we present a new line of controllers for brushless motors named SPIN. Our intention was to implement into
the new design the best experiences and know-how collected o er the last ten years with brushless controller
de elopment.
All controllers contain a new type of oltage regulator for the recei er and ser os, the so called switched BEC. Owing to
this element a considerable increase of applicability of controllers with BEC towards higher numbers of flight battery
cells could be achie ed. Another ad antage is the independence of ser o numbers of the input oltage.
General connecting conditions of the controller:
●apply only new high quality connectors properly soldered to the cables
●for controllers SPIN 11 and SPIN 22 we recommend G2 connectors, for the higher types use G3,5 or G4. After
soldering of the connectors check if the springy front part remained rotary. It may happen that the flux rises
along the connector surface and in the worst case gal anically separates the springy part from the connector
body. A remedy is possible by washing the connector with a brush in nitro diluent. In operation see to it that the
connectors stay clean and the plug-in force remains high. If this force decreases replace the connectors
immediately. We recommend replacement of connectors after 1-2 flight seasons.
●the distance between motor and controller should not exceed 10-15 cm. Flight battery cables can be extended
to 20-25 cm
●connect the JR connector to the throttle channel of the recei er

Setting with the help of the R/C equipment
- connect the controller by means of the JR connector to the recei er throttle channel and connect the motor.
- shift the throttle stick to position „full throttle“, switch on the transmitter and connect the flight batteries.
- switch on the switch ( oid for SPIN 11), after fi e seconds four tones sound ♪♪♫♪. If the throttle stick is immediately
shifted back to low throttle position the alue of the full throttle position is stored in the memory (END POINT),
otherways follows:
♪ single tones - mode 1 Acro inrunner: - this mode is appointed to aerobatic models dri en by motors of
classic conception. (inrunner)
- brake not acti e
- timing 0°
- gradual switching off when 68% of the starting oltage is reached.
♪♪ two tones - mode 2 Acro outrunner: - this mode is appointed to aerobatic models dri en by motors of
the re ersed conception. (outrunner)
- brake not acti e
- timing 24°
- gradual switching off when 68% of the starting oltage is reached.
♪♪♪ groups of three tones - mode 3 Glider inrunner:- this mode is appointed to gliders dri en by motors of classic
conception. (inrunner)
- brake acti ated
- timung 0°
- gradual switching off when 68% of the starting oltage is reached.
♪♪ ♪♪ groups of four tones - mode 4 Glider outrunner: - this mode is appointed to gliders dri en by motors of the
re ersed conception. (outrunner)
- brake acti ated
- timing 24°
- gradual switching off when 68% of the starting oltage is
reached.
♪♪ ♪♪♪ groups of fi e tones - mode 5 Heli constant RPM:
- this mode is appointed to model helicopters with the claim
for constant speed regulation with changing load/unload of the
rotor. This mode does not support fast speed changes
- timing 0°
- gradual switching off when 68% of the starting oltage is reached.
♪♪ ♪♪ ♪♪ groups of six tones - mode 6 Heli constant RPM (3D):
- this mode is appointed to model helicopters with the claim for
constant speed regulation along with fast changes - timing 0°
- gradual switching off when 68% of the starting oltage is reached.
Confirmation of the setting is carried out by shifting back the throttle to low throttle position during the tone signals of
the factual mode.

Setting with the help of the JETI-Box
This setting is carried out by means of four push-buttons: left , right , up , down .
Plug in the JR connector of the controller into the plug designated Impuls + - , which is positioned on the right side of
the JETI-BOX
Before connecting the flight battery remo e for the sake of safety the propeller.
Do not connect anything to the connector designated with -+ .
Connect the flight batteries and switch on the switch ( oid for Spin11). On the display appears the name of the
connected controller. By means of the push-buttons L and P more detailed informations are acquired of your controller.
By means of the push-button D we get to the option line of basic régimes where we either can choose reading out of
measured alues or setting of controller parameters (Measure or Setting), with push-buttons L and P we choose

Remark concerning current measurements:
1.) In order to measure correctly, the controller must run at full throttle at least 4 s in the course of the whole flight.
In case of constant rpm setting (Heli const. RPM) this condition may not be fulfilled and the measurement will not
correspond to real alues.
2.) The real a erage current may tra el between the measured alue of maximum and minimum current. According
to flying style it may approach one or the other alue.

The controller registers the o erall motor run time. The time is measured from
the first motor re olution.
The controller measures the o erall time from the first switch-on of the
switch (acti ation of the controller) until switch-off of the controller.
Set the number of motor poles by means of the push-buttons L-P . This
parameter is important for correct readings of the max. rpm.
Set the gear ratio of the gearbox. Apply 1:1,0 for direct dri e
In the course of operation the controller registers the max. motor rpm and the
time at which these rpm ha e been achie ed.
The controller registers the max. rpm of the propeller in the course of operation
and the time at which these rpm ha e been achie ed.
If parameters ha e been exceeded – oltage (U), temperatures (T), com-
mutation (C) and current (I), protections will be acti ated and the motor will
be cut-off. The reading y means that parameters became exceeded (an
error occurred), the reading n indicates that parameters ha e not been
exceeded.
With the help of this error notification the cause of motor cut-off can be
determined.
Remark. Protection in case of incorrect commutation (C) – if operation
becomes unsafe due to many commutation errors as a result of incorrect
motor design. In some cases this problem can be sol ed by increasing the
motor timing.

By means of the push-buttons L-P we set the speed of balancing rpm de iations. The
smaller the number, the faster are the inter entions. We always proceed from the higher
number. If a certain limit becomes exceeded the controller starts to operate unstable
(analogy with an o ergyrated Model helicopter)
Motor timing (pre-ignition) – setting by means of push-buttons L-P.
Recommended alues: 2pole motor...0-5°, 4p motor...0-10°, 6p motor..0-20°, 8p and
more...20-30° - necessary in case of the so called re ersed 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 alue must be. For big re ersed 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. oltage 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.
oltage per cell.
Information about the preset cut off oltage. With NiCd/NiMh cells or when setting the
automatic detection for LiIon/LiPol cells this alue results of the actual oltage of the
connected flight batteries.
Mode of motor cut-off when the oltage of the flight batteries decreases to the preset
alue. 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.

The initial regulation point ser es as instantaneous alue of the motor throttle stick in the stop
position.
setting of the initial regulation point as fixed alue in ms. The setting
of the alues is carried out by means of the push-buttons L-P.
With the push-buttons L-P we adjust the required full throttle alues. This alue can
also be set with the help of the transmitter (see Setting with the help of the R/C
equipment).
Automatic extension of the regulation range when in the line END POINT the set pulse
width is exceeded
Fixation of the set alue in the line END POINT as “full throttle”
position, when this alue is exceeded no extension of the
regulation range occurs.
Regulation curve:
- Logarithmical – a logarithmic course of rpm with the throttle stick displacement (linear
power course with the throttle stick displacement). This course is applied if most of the
flight time is carried out within a region of 50% of full throttle.
- Linear – a linear course of rpm with the throttle stick displacement . This course is
applied if most of the flight time is carried out within a region of 30% of full throttle.
- Exponential – an exponential course of rpm with the throttle stick displacement.This
course is applied model airplanes.
Direction of motor rotation is set by means of push-buttons L-P

If acti ated, it announces 5s after controller acti ation without turning the motor by
means of beeps the actual timing condition as shown by the following table:

We apply this mode for putting the controller into operation in
a fast and simple way for instance after loosing track during
setting. The setting content is practically the same as setting
with the help of R/C equipment. Confirmation of the setting is
carried out by means of the push-button P.

Remark 1: Extending the battery cables
As a matter of principle only cables from the battery to the controller can be extended. If the extension is larger than
20 cm it is una oidable to connect between the cables a low impedance electrolytic capacitor of a capacity 100-300 µF.
These capacitors must be inserted between e ery cable section longer than 25-30 cm.
Remark 2: Multi motor models
We recommend to use the same controller type for each motor. In case of SPIN controllers switch on only one BEC.
The switches of the other controllers remain in the “SWITCHED OFF” position.
When using controllers with BEC it is generally necessary to use only one common flight battery. If we want to to utilize
2 and more batteries these must be connected in parallel.

TIP:
If you do not know the pole number of your motor please contact the manufacturer.
If you own a re olution counter and know the gear ratio of your gear box (direct 1:1) you will be able to find the pole
number as follows.
Switch on the motor and with the help of the re olution counter measure the maximum propeller (rotor) rpm. Connect
the JETI Box and go in the menu MEASUREMENT to the maximum propeller RPM display (Max. Prop RPM). If the
shown alue does not correspond with your measured alue check the gear ratio setting (Gear) and change the pole
number inputs until your measured RPM will be identical with the alue in the JETI Box display (Max. Prop RPM). As a
result you will obtain the pole number of your motor (Motor Pole No.)
