Hobbywing Platinum Pro 120A Regler V4 3-6s, 10A BEC
Product information "Hobbywing Platinum Pro 120A controller V4 3-6s, 10A BEC"
The Platinum series from Hobbywing includes professional controllers for airplanes and helicopters with the best and most reliable performance that you expect as a professional pilot. They also have many advanced functions such as the Governor Mode for helicopters. The firmware can be updated by the user to always be up to date. This controller series is ideal for experienced pilots with a lot of experience as well as pilots who place great value on performance and quality.
With this extremely reliable and more than powerful controller, you will catapult your helicopter into new spheres. Precise flight figures and sensitive throttle response are now a matter of course. With the soft start-up function, there is no more tail drift and you have an optimal starting situation right from the start.

Excellent engine speed control "Governing"
A 32-bit high-performance processor with a frequency of 72MHz coupled with an advanced algorithm enables excellent control of the engine speed under a wide range of conditions. In combination with the possibility of setting the various parameters of the throttle response (Governor parameters), you can be sure of having sensitive and precise control over the speed that meets the needs of every pilot.

Driving Efficiency Optimization Technology / High Reliability & Efficiency
The "Driving Efficiency Technology (DEO)" reduces the operating temperature of the controller, increases the flight time and provides a consistently stable performance. Thanks to an active brake, the motor can reduce its speed extremely quickly when the throttle is released, meaning there is a much faster response to movements of the throttle lever. This enables the pilot to fly maneuvers such as extremely sharp turns, sudden changes in altitude or sudden braking even more easily.
With the DEO technology, the controller temperature is reduced by up to 10% and efficiency can be increased by up to 10%.

High-performance HV BEC
The integrated switching BEC has an adjustable voltage range from 5V to 8V and can be constantly loaded with 10A and briefly even up to 25A. There is therefore enough power available to achieve fast and precise control for your HV servos.

Super smooth start
The Paltinum v4 series allows the motors to start super smoothly and prevents "tail drifts". The start time can be set between 8 and 25 seconds so that the ideal starting situation for every flight is achieved.

Four brake modes
The Platinum series has the following brake modes - brake deactivation / normal brake / proportional brake and brake reversal. The braking force is adjustable with the normal brake, in the proportional brake mode the braking force is automatically adjusted depending on the stick movement and with the brake reversal the rotor rotation direction can be reversed using an additional channel.

Multiple protection mechanisms
It has numerous protection functions such as against controller overheating, capacitor overheating, controller overvoltage protection, signal loss and undervoltage protection. Thanks to all these protection mechanisms, you will be able to enjoy using the controller for a long time.

Additional features
A separate programming port on the controller allows you to

to program the controller
to check the flight data such as min. voltage, max. temperature, standard rpm and throttle curve (in Heli Governing Store Mode)
