Well the one top left is your throttle and bottom one goes to your front wheel and rudder so the one top right is your elevator . . They are all missing screws thoand your picture has the elev and rudder crossed . Your nose steering wheel is always hooked to your rudder servo not the elev. So unplug the two and switch them on your reciever . Or if the top right is your rudder hook up the nose wheel push rod to it . Just call me if you still have my number .lol joe
