Description

We are proud to offer our Hobbyking RotorStar ESC series. With helicopter specific programming options such as super smooth soft start, fixed RPM mode (governor mode) and ultra high resolution, you won't find a better helicopter ESC on the market today!

We have tested these units on our own helicopters and found them to be among the best we have ever seen. The super smooth soft start, along with its ultra high resolution throttle response puts this ESC in a class of its own!

RotorStar ESCs are built with the highest quality components to ensure true-to-rating current handling and high efficiency operation.

All RotorStar ESCs can be programmed via optional programing card or by transmitter stick inputs.

Features:
• Powerful 5.5V/4A Switching BEC
• Optional programming card for convenient setup
• Super fine throttle resolution provides first-rate and highly accurate linearity
• Super smooth adjustable start-up mode
• Constant RPM mode (governor mode)
• Adjustable F3A brake. 
• 3 steps adjustable normal EMF brake 
• High anti-interference capability
• Low voltage cut-off protection with automatic adjustment for NiCd/NiMH/Li-Ion/LiPo/LiFePO4 
• Soft cut-off option at low voltage, slows motor RPM gradual rather than hard cutoff (LVC)
• Low voltage cut-off can be disabled 
• Variable cut-off voltage / cell   
• Active free-wheeling circuit allows for unlimited "partial load" capability
• LED status display 
• Adjustable motor timing from 0° to 30° 
• Blocked rotation protection (senses a jammed motor and stops motor rotation) 
• Motor reversing from ESC (no need to change ESC/motor wires)
• Over-temperature protection and overload alarm 
• Throttle signal lose protection. If the signal is lost for 3 seconds, the power will automatically cut-off. 
• Safe power-on. (Motor will not start until throttle is returned to lowest position)

***This ESC is compatible with both helicopter and airplane models.***

A complete waste of money, it worked a few minutes with a really strange behaviour on my little foamy with a little motor on 2S, so no overload, then never started again, with the motor doing exactly like when you take off one of the 3 wires, and it beeps 6 times always now whatever i try to do, so i guess it just fried during the night lol ! The only thing i could tell people is: DON'T BUY THIS ONE AND CHOOSE ANOTHER, i'm gutted: garbage bin for it.

As the rotor Star 30A this controller is useless also. I have bought 2. Both have the same problem. Setting: PWM 8kHz and Auto Timing, Governor and Brake = OFF, Quick Start, battery = 3s. I have 5 different motors connected with different Kv and size. For all shows the same error: In a certain throttle position in the top third of the gas the speed breaks to lower, and then increases with increasing gas again (like a gear). At decrease of the gas, the speed jump to a higher value around about the sam gas value. It seems that the software is the same and has the same error
