18A Soaring Brushless Motor Speed Controller (ESC) Leopard Hobby

Features:

• Extreme low output resistance, super current endurance.
• Multiple protection features: Low voltage cut-off protection / over-heat protection / throttle signal loss protection.
• 3 start modest Normal / Soft / Super-Soft, compatible with fixed-wing aircraft and helicopter.
• Throttle range can be configured to be compatible with all transmitters currently available on market.
• Smooth, linear and precise throttle response.
• Separate voltage regulator IC for microprocessor (except Soaring-6A and Soaring-1 OA) with good anti-jamming capability.
• Supported motor speed (Maximum): 210000 RPM (2 poles), 70000 RPM (6 poles), 35000 RPM (12 poles).
• The pocket-sized Program Card can be purchased separately for easily programming the ESC at flying field.
• With a program card, user can activate the music playing function of the ESC, and totally there are 15 songs can be selected.

Programmable Items:

1. Brake Setting: Enabled / Disabled, default is Disabled
2. Battery Type: Li-xx(Li-ion or Lipo)/Ni-xx(NiMH or NiCd). default is Li-xx.
3. Low Voltage Protection Mode(Cut-Off Mode): Soft Cut-Off (Gradually reduce the output power) or Cut-Off (Immediately stop the output power). Default is Soft Cut-Off.
4. Low Voltage Protection Threshold(Cut-Off Threshold): Low / Medium / High, default is Medium.

• For lithium batteries, the number of battery cells is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.85V/3.15V/3.3V. For example: For a 3 cells lithium pack, when “Medium” cutoff threshold is set, the cut-off voltage will be:3.15*3=9.45V.
• For nickel batteries, low / medium / high cutoff voltages are 0%/50%/65% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: Fora 10 cells NiMH battery, fully charged voltage is 1.44*10=14.4V, when “Medium” cut-off threshold is set, the cut-off voltage will be:14.4*50%=7.2V„
