It is 100% for rudder authority on single engine. When you go single engine on non centerline thrust you are basically throwing full rudder to counter the yaw. 

I will be the cynic here, in their specs they are listing a fuel burn of 12 gph at Eco cruise. I don't think I have ever been able to get an IO 320 to burn 6 gph - but that was single eng. 

Also curious about performance with single engine when close to gross weight and or high density altitudes. Claiming 320fpm but there is an asterisk that is not explained.

There are definite times to having more than one engine. Over water being the most important but I am not sold on the comments about night flying or IMC single engine.

It will definitely be a cool project to watch grow though. And two nicely tuned 180hp Mazdas would make this a great aircraft for sure.

Maybe for a bit more rudder authority in case of one engine out?

How weird to see a velocity with a vert stab.  Wonder why they changed the configuration.
