Ultra lightweight & small 7-channel 2.4 GHz RASST receiver for indoor / outdoor use up to 300m. With serial output. Perfect for control of micro-helicopters. A serial output at the receiver requires special components in the model which can read the pulse chain & can process further accordingly, such as the HC 3 Xtreme or mini V Stabi. No traditional servos are directly connectable. No crystals, no frequency channel selection & maximum security from common channel interference by 2.4 GHz FASST technology. Optimum suppression of interference signals due to fast frequency hopping. High intermediate frequency of 800 MHz & thus insensitive against electro-smog. Simple integration through integrated EASY-Link button. Can be used with all FASST transmitters from 6 channels in the 7-channel mode.
