If one engine quits, cut the power on the other one. Especially if you are slow. There is a speed known as Vmc in full scale. It is the speed at which you loose directional control if one engine is full and the other is off, basically. If the plane is slow, you won't have enough rudder arm to compensate for full power only on one side. Keep the speed up and you will have less problem. If you are slow, pull the power, get the nose down and commit to land if you are low. It will save the plane. I was behind a guy one day that lost one and went full on the other. Went into a spin. I kept yelling "shut it off, shut it off". he finally did and pulled out just in time. should be a good plane. Let me know if that is enough power. I was thinking of using those engines but am going with .46 FXs.
