banktoturn - I agree that for all practical purposes that building a straight aircraft that is symmetrical in all respects (with thrust adjustments) is the way to go. In other words, when it comes time to actually build a model, I agree 100% with what you said.

However, I was asking from a strictly theoretical standpoint. I don't think any model manufacturer has the means or the research staff to do what I'm asking about so it's really a moot point. It's just something I'm curious about.

probligo - I'll check out that link. Thanks.
