RadioLink Be T8FB BT (Bluetooth) 8 channel M1 with R8EF receiver

(This text is machine translated) T8FB BT (Bluetooth) 8 Channel M1 with R8EF Receiver Protocol Update The T8FB, with TI CC2500 chip(Open TX, the same as Frsky X9D) and three times faster transmission rate than Open TX , uses the AT9S's Spread Spectrum protocol and 16 pseudo frequency hopping channels which makes the T8FB have better anti-interference capabilities both on the same frequency band and on different bands. The range on the ground is 500 m and in the air 1000 m, which is double the T4EU, T6EHP-R and T7F. Improved Stick Accuracy Redesigned circuit layout gives a max PWM signal vibration of 1.84us, and normal vibration is 0.5us (as on the AT9S), that's 4 times better than old versions of T8FB and 14 times higher than a famous racer drone transmitter which shows 7 us, it's much better than competition transmitters. The sleeves use the same components as the AT9S. S-BUS, PPM and PWM support Sold with an 8-channel R8EF receiver, S-BUS, PPM and PWM signal outputs are possible at the same time. No need...
