J:

Do a quick search for the posts of "Ed Moorman," He is a great proponent of out thrust, and has settled (I think) on eight degrees out for each engine.

This is great if you want engine out to fly exactly as the plane does with both running, only less speed.

I just don't like the sight of the engines pointing out sideways, mine are all dead away except my very first twin, and the ARFs that come with side thrust built in. When I lose an engine it's throttle down time, crank some rudder in, and land.

Your choice.

Bill.
