The SPIN controller family for brushless (AC) motor control are able to operate with all types of batteries like NiCd, NiMH, Li-Po, Li-Ion and LiFe (A123). Due to their numerous adjustment possibilities they are preferred for all airborne applications including helicopters and belong to the usual equipment of top pilots.In the course of development of new brushless motor controllers we were eager to fulfill most user require-ments and at the same time offer a product with simple handling properties and high comfort.

All controllers comprise a new type of voltage regulator for receivers and servos, the so called switch mode BEC with a voltage of 5,5 V. By application of this unit a way was opened for BEC systems even in models with higher cell numbers. It must also be taken into account that the number of servos became independent of the level of the supply voltage.Adjustment of the SPIN controller family is carried out via the JETIBOX. By connection of the SPIN controllers and the JETIBOX a new system is formed which allows optimum set-up of any type of drive.


These controllers comprise a receiver voltage supply with complete galvanic separation of the driving system and hence a minimum receiver interference. This, of course, induces the necessity of a separate battery supply for the receiver and servos. SPIN controllers can be easily programmed without a computer – all you need is a JETIBOX. SPIN controllers are also able to store operational data and by this means you are in a position to check and set adjustments of your model airplane or helicopter.

Measured data of controller tem-peratures, maximum and minimum currents, speeds, motor runtimes and many other parameters become stored and can be read out by the JETIBOX directly after flight termination. This enables you to change your adjustments and fly again – you will immediately see results. Fine tuning of your motor was never easier.


  • Use AUTO SETUP and choose - mode 2 - OUTRUNNER to reach optimal bacis setting with AXI.
  • In case you want to tune fine your power unit use MANUAL SETTING and set following bacis parameters for all AXI motors*: TIMMING 24°, FREQUENCY 8 kHz, NUMBER OF POLES 14* Other parameters can be set due to your needs but please always respect SPIN instruction manual.


* for AXI 2217/5H set NUMBER OF POLES 8, all other AXI motors has number of poles 14.
