OP I think you're comparing apples to oranges here anyway.

As a instructor on DC 9's, when was the last time you you put that thing into a hover, or used a "bank and yank" to turn around, or (gasp) fly it inverted? Or for that matter, put a Cessna 172 into sustained inverted flight? I may be wrong, but most full size aircraft are designed to fly upright and at a designed constant cruising speed. Once up to altitude, trim it out, and put the thing on auto pilot, go get a cup of coffee, sit back and relax. All fine and dandy to have a lifting tail to help git this bucket of bolts into the sky under these conditions.

I don't see any kind of lifting tail being beneficial on a model aircraft though. We're not going up, reaching designed cruising speed and drinking coffee going to Minneapolis. (pick the city of your choice or 150 mi beyond if you're busy...LOL)

Give me a neutral tail for ballistic guidance and nothing else.

Everyone say Ahmen!
