RE: twin engines angles
Bill & I are friends-we are in the same club. He is sort a "do it the manual way" person and I love gadgets and new technology and have this compulsion to fix things. Certainly, you can fly a twin with the engines at any angle you want and I have twins with the engines straight ahead.
What I have been doing for the past few years, and writing about in my R/C Report columns, is to experiment and test many things that might be of interest and help to the average flier. Out thrust on twins is one of those items. I read here occasionally about someone who has lost a plane after havng an engine failure and then couldn't handle the plane on one engine. This is a guy who may not buy another twin. I think I'd like to see more people flying twins, so why not let's make it easier for them. For a newcomer to twins who isn't really too sure of his skills, I think using out thrust may save him in a bad situation.
