The model is powered by 2 x 550 motors, 1 x ESC and 1 x 7.2v 2000mA Nicad. All the lights work from a 9v block rechargeable battery, the switch being hidden in the left forward locker, the r/c switch in the other locker. Sentinel is a bit on the heavy side but does have a good turn of speed. Because of the high superstructure she is best sailed in no/very light winds.
