with the 15's on this plane it will not fly on one engine .25 is about the minimum for single engine flight.what will happen if you lose an engine is the good engine will raiise the wing and start to roll all you can do is cut the other engine to idle or kill it,if you are abl.e to stop the roll as the plane slows down and the wing with the dead engine stalls it will do the samething but you will be flying to slow to stop it without gaining airspeed,only way is to dive but hard to do while rolling.just be prepared as the plane is some distance from you due to the lag from the sppeed sound travels by the tome you hear the engine dying it has allready quit,just watch for a wing to start rising without any control input as this is a sign that an engine is going sour or quit and use rudder to correct not airlerons..for instance the right wing rises unexpectely use right rudder to correct if it keeps rising throttle back,this will all happen in a blink of an eye.the larger engines will keep the airspeed at a safer speed on one engine so that it is controllable.
