I love the B-25. It's a great looking plane and my ten minutes of stick time showed it to be a great flying plane with balanced controls. I"ll never forget that flight !

Now to the model... Increasing power in a twin is not always the answer to perceived problems. Just what makes you think you will need more power? This was a light bomber and not a fighter, so loops were not in it's flight envelope. I'm sure it would probably roll, but again, it's not something a pilot flying one woulld do very often, if at all. If you are concerned with single engine performance, more power just means a faster spiral into the ground. Huh?

If you are familiar with twin engine planes (as in full scale multi-engine rated) or models, then you already know that if you lose an engine, you must be at or above a minumum speed in order to have enough rudder available to compensate for the drag and loss of power on one side. If you are below that speed, more power won't save you as it just increases the need for more rudder. Trying to stop the roll that develops with aileron just increases the problem (it increases adverse yaw on the dead engine side). Airspeed is the answer and lowering the nose and MAYBE reducing power to bring the plane back into balance is often the answer.

Adding a more powerful engine will increase your speed slightly, but does require an awareness of the problems mentioned above. Adding more power in an engine out situation WILL require a higher airspeed to be able to control the increase in yaw (notice I did not say roll- that is the result of uncontrolled yaw).

Good luck and keep us informed...
