Speed ​​controller MASTER Senstrol 120A Opto

Product description and features
The controllers of the Hacker MASTER Senstrol series are real sinusoidal commutating speed controllers developed and manufactured in Germany. The motor current is regulated sinusoidally in order to achieve an optimal torque-per-ampere ratio in the motor. The sinus commutation offers a smoother motor run, less switching losses and thus less motor heating. The efficiency of the entire drive is increased.

The Hacker MASTER Senstrol speed controllers have been specially developed for the Senstrol versions of our Q80, C50 and C54 engines. The motor’s status is constantly monitored by the built-in motor identification chip and special sensors within the motor.

Motor / controller synchronization
In order to guarantee a 100% adaptation of the entire drive, we measure the motors precisely and save the data on the chip built into the motor. This can only be used if the Hacker MASTER Senstrol speed controller is connected to the motor identification chip.

The motor identification chip contains all the data relevant to the motor and provides the necessary motor parameters during operation. This completely eliminates the need to program the motor parameters separately.  Much of this data can be adjusted by the pilot himself according to individual requirements, but not beyond the preset limit values. It is therefore no longer possible to overload the motor.

Real sinus speed controller
The MASTER Senstrol is a real speed controller.  Due to the speed mode specially developed for our F3A and aerobatic pilots, the speed of the engine is determined by means of the throttle stick. The speed remains constant in both upward and downward passages. It is no longer necessary to adjust the “brake”. This finally fulfills the long requested wish, especially in F3A aerobatics, to be able to regulate the braking effect of the motor at any time and very precisely.

Of course, the Hacker MASTER Senstrol speed controller is not only the first choice for our F3A customers, but also for every pilot who wants to combine maximum performance with maximum efficiency and smoothness.

Different modes of operation
In addition to the usual gas channel, a second switching channel can also be used, e.g. with a 2 or 3 step switch. For this purpose, the MASTER Senstrol speed controller has a second JR / UNI connection cable to the receiver, so that the MASTER Senstrol can be switched to 3 different operating modes:

• Protection mode is engine off
• Speed ​​mode for F3A / aerobatics
• Torque mode
