Description: T8FB 2.4GHz 8CH RC transmitter has been upgraded, based on the old version. Now, the transmission rate is three times faster than OpenTX, and the stick precision 15 times more accurate. It comes with R8EF receiver and supports SBUS, PPM, and PWM signal output. The Switching Mode Power Supply ( SMPS ) keeps the operating current less than 80mA, which means that if you connect it to a 3S 1800mAh LiPo battery, it can work for more than 20 hours.
Main Features: ● With TI CC25000 chip ( OpenTX, same as FrSky X9D ), upgraded FHSS protocol, and improved stick precision ● Supports SBUS, PPM, PWM output; online upgrade via computer; parameters setting via Android App ● Suitable for most kinds of RC airplanes, RC cars, and boats, up to 1000m control distance ( free of interference ) ● Extremely power-saving, 80mA low operating current; supports 2 - 4S battery and 4.8 - 18V input voltage
