Attention: automatic translation follows!

Features:
1. Adopt small high-speed MCU with powerful functions.
2. With low voltage protection; over temperature protection; throttle signal loss protection; motor start protection; power-on self-test and so on.
3, soft start, 4 seconds super soft start function for helicopter. When starting the helicopter, no impact and no tail slap can be seen.
4. It has good takeoff performance, good throttle linearity and fast throttle response.
5. Very good low speed performance.
6. The maximum supported speed is: 240,000 rpm (2 magnetic poles), 80,000 rpm (6 magnetic poles) and 40,000 rpm (12 magnetic poles).
7. MCU and BEC use different voltage regulators that are independent of each other, improving noise suppression capability.
8. Built-in linear BEC or switching mode BEC.
9. Several parameters of the controller can be set by the programming card or remote control.
10. The programming card adopts LCD display, which is convenient and intuitive.
11. The low voltage protection threshold and starting power can be quantified and set accurately through the programming card.
12. The gas stroke can be adjusted to be compatible with different receivers.
13. There are 3 throttle curves available. Motor reverse can be adjusted.
14. 7A, 12A ESC supports 1 lithium battery, the minimum working voltage is only 3V.
Parameters that can be set by programming board:
1. Undervoltage cutoff voltage: setting range: 00.0V-49.9V, default is 00.0V. Depending on the battery used, it can be set to any value within the range as low voltage protection voltage.
Note: When the setting value is 00.0V, the system automatically detects the number of lithium batteries currently used at power on and calculates the low voltage protection value. 2.85 V is the protection voltage of each battery
For example, for 3 lithium batteries, the low voltage protection value is: 2.85 V x 3 = 8.55 V.
2. Brake type: three options: no brake, soft brake, hard brake. The default setting is no braking. Soft brakes have longer braking time and fixed brakes have shorter braking time. After braking
The motor stops, but the brake remains until the motor is restarted. The soft and hard brake options are designed for gliders and are particularly suitable for folding propeller planes.
3. Electronic timing: three options: low timing, medium timing, high timing. The default value is the medium angle. Low timing is suitable for motors with large inductance and low speed. High timing is suitable for inductance
external rotor motor with small volume and high KV value. For some high KV motors, if the motor wobbles during high speed operation, it must be changed to high timing.
4. Start mode: three options: Quick start, soft start, super soft start. The default setting is quick start. Quick start and soft start are suitable for fixed-wing aircraft.
Both soft start and ultra soft start are 4 seconds extra soft start. During the 4-second start, the propeller speed increases slowly and during the soft start, the speed increases slightly faster.
Ultra-soft start is slower, which is especially suitable for helicopters. In soft mode or super soft mode, if the engine stops within 4 seconds
When the engine restarts, it is a quick start. If it is longer than 4 seconds, it is an extra soft start for 4 seconds.
5. Shutdown mode: Two options: Reduced power (soft shutdown), immediate shutdown (hard shutdown). The default setting is reduced power. Low battery voltage protection.
Select to shut down immediately. When low voltage occurs, shut down the motor immediately.
Select to reduce power consumption. When the voltage is too low, the output power is gradually reduced to 50% of the current power (i.e., the power when there is no low voltage).
6. Choke curve selection: three options: CURV1, CURV2, CURV3. Different throttle curves are used to meet different applications.
7. Set start power percentage: This is to set the starting power. Setting range: 00% -39%, default setting is + 00%. With a default setting of + 00%, the starting power is automatically determined by the system based on the throttle position. When it is
