Ok. I am currently building a Top Flite DC-3 hopfully ready for spring 2006. Top Flite designed the DC-3 differnt from the Twinstar and other twins. Both engine mounts have opposing thrust built in. Basically the left engine points a few degrees left and the right points a few degrees right. What this does is when running both engines there thrust is balanced so the opposition in thrust angles cancels out, but if an engine dies the good engine is pulling the A/C in the opposite direction. It's like stepping on the rudder to compensate for the dead engine. If you do use rudder and slam it 100% toward the good engine then you can have too much correction. Of course I haven't flown my DC-3 yet so I can't speak from experiance but the design of this model helps with engine out situations.
