This kit contains 4x Brushless 1000kv motors, 4x 30A ESC and 4 pairs (8 pieces) of 1045 propellers.

Safety arming feature: regardless the throttle stick position, the motor will not spin after battery connected.
Throttle calibration: throttle range can be configured to provide best throttle linearity, fully compatible with all market available transmitters.

Programmable items:
Brake setting: brake enabled / brake disabled.
Battery type: Li-xx(Li-ion or LiPo) / Ni-xx(NiMh or NiCd).
Low voltage protection mode (cutoff mode): gradually reduce the output power / cutoff the output power.
Low voltage cutoff protection threshold (cutoff threshold): low / medium / high.
Start mode: normal / soft / very soft.
Timing: low / medium / high.
Reset: reset all the programmable items to their default settings.
Full protection features: low voltage cutoff protection / over-heat protection / throttle signal lost protection.
