Hi there

I brought a flysky IT4 radio and have installed it and have no reverse

Have tried it on to cars

car 1 have throttle no brake, no reverse
TT01 With 540 Tamiya RZ, DE10 ESC, Nano tech 4600 mah 90c battery

Car 2 Have throttle , Brake, No reverse

TT01, Yeah Racing XTA 5.5T,Speed Passion Aventador S 80A Sensored Brushless Waterproof ESC , Nano tech 4600 mph 90c battery

these cars both had reverse before but no anymore

Any ideas ?
