bjl, where do you fly?

The use of rudder is among the last skills that most pilots learn...some never do. The key is to fly the airplane and keep it under control. Usually the only way you will know an engine has quit (especially with other models in the air) it that it will slow down significantly, and may, or may not start to turn, depending on the model. Most people will never figure out which engine has died, especially if they have to analyse the situation and decide whether left of right rudder is needed.......by that time the model is out of control and headed down in a spin. Fly the airplane! If it slows down, stuff the nose down to keep the airspeed up...come back on the trottle (as mentioned above) when the plane is under control slowly feed throttle back in (don't slam it to full throttle!!) Even if you only get to half or two thirds throttle before it starts getting squirrelly, it will reduce your rate of decent and give you time to plan a landing.
Altitude is your friend in a twin. You can exchange it for airspeed to keep the plane flying under control; it gives you time to think, and it gives you gliding range to make it back to the runway..


But, to get back to your original question. The easiest way to save it is to throttle back and land, same as you would if a single engine plane had a dead stick
