40A Brushless Speed Controllers for air

1)Super fine and smooth touch of speed controlling, first-rate accurate linearity and quick-respond speed of throttle. 2)Separate voltage regulator IC for MCU(Micro Controller Unit),high capability of anti-interference to decrease the possibility out of control. 3)Low-voltage cut-off protection of battery,blocked rotation protection an throttle signal lose protection,etc.All these functions can prolong the service life of ESC effictively. 4)It can be compatible with a programming card(optional component),which has a simple and visual surface so as to change the parameters conviently at any time anywhere(reference to the manual for programming card). 5)Good and safe performance of power-on.The motor won’t be started no matter which position the stick is in when the battery is connected. 6)It is a Water proof, Speed Limit and special designed esc for Air. 7)It's also the first choice as Christmas Day gift for both children and adults. · Weight: 47 g · Size: 66 x26 x12mm · Constant Current:40A · Max Current: 50A (for ten seconds) · FET: 24 · SBEC: Yes, 6A · PWM: 8 KHz · Input: 2 to 6 Li-Po, or 6to16Ni-MH/Ni-Cd
