Multi-Mos series

Smaller, more powerful and easily programmable, were the conditions for the new controller generation of aero-naut. The speed controllers of the Multi series are designed for driving models with reversing polarity for forward and reverse travel.

Due to the high clock frequency of 16 kHz, the otherwise annoying whistling sound of the engine is no longer audible. This new generation of these speed controllers features state-of-the-art digital technology microcontroller technology. Programming is permanently stored in the Eprom until it is reprogrammed. Only the neutral position, the full throttle position and the battery type NiCd or NiMH batteries or Pb batteries are specified. The selection of the EMF braking function is made by a jumper.

In free-running operation, the engine is braked in the neutral position. Only when the control stick is moved beyond the zero point in the other direction does the EMF brake brake the motor proportionally. With this setting LEDs can be controlled as brake lights. A change of direction is only possible when the engine has come to a standstill.

During engine braking, the engine will decelerate as normal as with an active EMF brake. The direction of travel can then be changed at any time.
