This will be my first twin engine plane and I want to do it right. I bought a perfectly good Enforcer delta and am modifying it for two Norvel AX-40's. I built a horizontally mounted plate to mount the engines above the wing spaced to use 3 blade Master Airscrew 9 x 7 pusher props. The engines are raised 3" higher than the stock OS .91 four cycle was. I plugged the original prop hole in the wing and the new props clear the wing by 1/4" and the fins and each other by 3/16". I retained the original down thrust.

My questions are (to help the stability if one engine quits);

Should I build engine side thrust, that is, aiming toward the center of the wing (because they're pushers)?

Should I install a rudder behind each prop for control if needed? (The original Enforcer has no rudders). How about each rudder turned out when in neutral so the engine that did not quit is trying to correct the engine-out turn?

I was going to try both methods above unless more experienced flyers have better ideas.

Anyone done this before?
