My Twinstar required very little set up. I put two new Magnum .36s in it, started them up rich and ran them for a while. I then leaned them out and tached them, they were both within 200 rpm. So, I took off and flew the thing. It is amazingly simple to fly. I always though a twin would be a pain but this one has been very easy to fly, set up, and maintain. If fact, I have another one sitting in a box, I might take the extra wing nacelles and make my Twinstar a quad. Engine out situations are no biggy. Just add rudder into the live engine. I've even done loops and rolls with only one engine. 5 degree offset in the engine help a lot.
