Flycolor Raptor 15A BLS-Mini 3S

1)Ultra small size, more suitable for small multirotor.
2)BLHeli-S firmware is designed for superior performance in multirotors, and uses hardware generated motor
pwm for smooth throttle response and silent operation.
3)Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active
freewheeling.
4)Supports Dshot150, Dshot300 and Dshot600.Dshot is digital signal, anti-interference ability is stronger, and do not need throttle calibration.
5)The silicone twisted-pair of the throttle signal cable increase the service life,and effectively reduces the crosstalk caused by signal transmission,
and makes flight more stable


Quantity:
1x Raptor BLS-mini 15A ESC


Main features

1) EFM8BB21F16G MCU, pipelined 8-bit C8051 core with 50 MHz maximum operating frequency.
2)Dedicated 3in1 driver, faster response.ESC maximum speed is limited to500k eRPM.
3) Ultra small size, more suitable for small multirotor.
4) BLHeli-S firmware is designed for superior performance in multirotors, and uses hardware generated motor
pwm for smooth throttle response and silent operation.
5) Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active
freewheeling.
6) Supports features to prevent sync loss. There are tuneable parameters that can make the code run well even in
the most demanding situations, although default settings will work excellently in normal operating environments.
7) The code supports regular 1-2ms pulse width PWMinput, as well as Oneshot and Multshot . The input signal is
automatically detected by the ESC upon power up.
8)Supports Dshot150, Dshot300 and Dshot600.Dshot is digital signal, anti-interference ability is stronger, and do not need throttle calibration.
9)The silicone twisted-pair of the throttle signal cable increase the service life,and effectively reduces the crosstalk caused by signal transmission, and makes flight more  stable

Programming parameter

Programming parameters below can be accessed from the configuration software (BLHeliSuite):

1. Startup power:
Startup power can be set to relative values from 0.031 to 1.5. This is the maximum power that is allowed during startup. Actual applied power
depends on throttle input, and can be lower, but the minimum level is a quarter of the maximum level. Startup power also affects bidirectional
operation, as the parameter is used to limit the power applied during direction reversal. For low rpms, the maximum power to the motor is limited,
in order to facilitate detection of low BEMF voltages. The maximum power allowed can be set via the startup power parameter.
2. Commutation timing:
Commutation timing can be set to low/mediumlow/medium/mediumhigh/high, that correspond to 0°/7.5°/15°/22.5°/30° timing advance.
Typically a medium setting will work fine, but if the motor stutters it can be beneficial to change timing. Some motors with high inductance can have
a very long commutation demagnetization time. This can result in motor stop or stutter upon quick throttle increase, particularly when running at a
low rpm. Setting timing to high will allow more time for demagnetization, and often helps.
3. Demag compensation:
Demag compensation is a feature to protect from motor stalls caused by long winding demagnetization time after commutation. The typical
symptom is motor stop or stutter upon quick throttle increase, particularly when running at a low rpm. As mentioned above, setting high
commutation timing normally helps, but at the cost of efficiency.Generally, a higher value of the compensation parameter gives better protection.
If demag compensation is set too high, maximum power can be somewhat reduced.
4. Direction:
Rotation direction can be set to fwd/rev/bidirectional fwd/bidirectional rev. In bidirectional mode, center throttle is zero and above is fwd rotation
and below is reverse rotation. When bidirectional operation is selected, programming by TX is disabled.
5. Beep strength:
Sets the strength of beeps under normal operation.
6. Beacon strength:
Sets the strength of beeps when beeping beacon beeps. The ESC will start beeping beacon beeps if the throttle signal has been zero for a given
time. Note that setting a high beacon strength can cause hot motors or ESCs!
