This invention is used to conveniently remotely tilt window blind slats using a wireless motorized/receiver unit and wireless transmitter hand held unit. The main unit described as the wireless motorized/receiver is comprised of a housing containing : 1-wireless receiver circuit board 2-d.c. motor with reduction gears 3-battery compartment 4-on/off switch 5-flexible spring drive 6-rubber pipe connector The transmitter unit is comprised of a housing containing : 1-transmitter circuit board 2-tilting direction operating buttons 3-battery compartment Mode of operation: The receiver/mechanical unit is positioned near the top of the window blind's tilting wand hook either on the window casement or the uppermost window blind housing by velcro or any form of attachment. The flexible spring drive can then be connected to this hook by it's pressure fit rubber pipe. Various positions for connection can be achieved lending through the flexibility of this drive. Pressing one of the two "tilt" buttons on the hand held transmitter unit activates the receiver in the mechanical unit thereby energising the motor/gear assembly via the on-board battery and rotating the connected flexible spring drive. As the flexible spring drive rotates it causes the horizontal window blind slats to tilt clockwise or anti-clockwise depending on the button pressed on the transmitter unit,
