Radiolink R8FM R8EF R8FM Rc Receiver 2.4G Signal for RC Transmitter Specification: Product name:R8EF Size:41.5 x 21.5 x 11.5mm Weight:14g Antenna length:210mm Number of channels:8 channels Support model:car/boat/glider/fixed wing Operating voltage:3V-12V Operating current:38-45mA(input voltage 5V) Frequency:2.4GHz ISM band Spreading mode:FHSS 67-channel pseudo-random frequency hopping Control distance:2000m in the air,actual flight distance varies with environment Compatible remote control:T8FB(standard)/T8S/RC6GS V2/RC4GS V2/RC6GS/RC4GS Signal output type:Support SBUS,PPM and PWM three kinds of signal output at the same time. Signal working mode 1.PWM signal working mode Receiver indicator is red, output 8 channels of PWM signal. 2.S-BUS/PPM signal working mode The receiver indicator is blue(purple),1 channel outputs S-BUS signal,2 channels outputs PPM signal,3-8 channel output the corresponding PWM signal,a total of 8 channels of signal output. R8FM Number of channels:8 channels. Operating voltage:3V-6V Operating current:30mA(input voltage 5V) Size:16.0 x 21.5 x 1.0MM Weight:2.5g Resolution:2048,0.5us per level of high precision,so that all the servos are as still as water Remote control distance:about 2000 meters, the actual control distance and flight environment has Compatible remote control:T8FB/T8S/RC6GS V2/RC4GS V2/RC6GS/RC4GS Signal output type Can output 8 channels of S-BUS or PPM signal. Receiver indicator in blue,output 8 channels of S-BUS signal. Receiver indicator is red, output 8 channels of PPM signal. Signal switching Short press the (ID SET) switch on the side of the receiver twice (within one second) to complete the switching of SBUS and PPM signals of R8FM. Package includes: 1 x R8EF receiver Or 1 x R8FM receiver Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
