My hitec one didn't have a metal one it had a super beefy looking plastic one. After some looking in the vast jungle of s#¡t I have I found an aluminum servo horn.
I tested everything out for just a second in my living room and it won't steer and go forward at the same time. If I stop it will steer and if I have the steering wheel neutral it will move forward and backwards. Good thing I already ordered the bec I guess.
