Never flown one but if this happened when I was theoretically flying I would shut power down keeping as fast a forward speed as possible controlling yaw(if any with throttle) and aim to run on at about 50 to 60ish knts,
Could be total boll**ks what I have just said but the speed would decay as you slowly closed the throttle and the forward speed ( would need to be checked whilst panicing) should be slowly reduced to try and stop any big yaw...
And hope I could walk after everything went quiet!!
