yes but not work this link on your forum : Click here to view the RC John Deere 8360RT Code, my problem ist not work controler-cab-body , problem has my serial comunnication and that’s why replace only two motor. control – body

[sisikar]

yes but only control arduino on arduino not serial communication.I build crawler and i like your steering RC John Deere 8360RT.
I have a functional model but need variables code for two motor control. code for Arduino in the control – code for Arduino in the body

left-right joystick X, forward-backward joystick Y
