Kent, you've made unbelievable claims about Twin Comanches that you haven't even flown. Andrew actually owned the plane in question and has the picture to show, plus admitted that it was in December at 76% power. I'd trust what he has to say about it.
WRT Twinkie claims, the only one I've made with certainty is the one I've flown - I think I've always qualified the others with "should be" or whatever.
Obviously, a picture is worth a thousand pilots' opinions, so I'm inclined to believe Andrew - But that doesn't mean it's easy.
I don't think there are any restrictions on what the manufacturers' marketing departments can claim their top speed is, so presumably they'd come up with those numbers under the most favorable conditions possible. Beating them, then, should be almost impossible.
However, I've also flown an old Seneca with 12,000 hours on it that got exactly book performance numbers (which surprised the hell out of me). So, that does show that the "new airplane, test pilot" fudge factor does not always apply.
Maybe Andrew got his extra knot from waxing it up real good.
It really amazes me how many people on here will state that his or her plane of choice is the best - absolutely, positively, you're a heretic if you disagree - and every other plane is complete garbage.
I never said the 'downer is complete garbage - And I would have no basis to, never flown one. I have heard that they have a nice, big, comfy cabin though. Like any airplane, there are tradeoffs that have to be made in the design. That's why we pick airplanes based on the mission - Your Aztec being much better for your mission (hauling a ton of dogs all over the place) than my coveted Twin Comanche would be, and the Twink being better for my mission (getting me places with two fans on as little fuel as possible) than the Aztruck.
IMHO, there are really VERY few aircraft types that are truly bad - It's just that each one is designed for a particular mission with particular goals in mind. OTOH, even the best-designed aircraft type has examples that are crap. It seems that in this thread we've gone right from the start into blaming the type for the shortcomings of one example.
You're right though, there's a lot of my-way-or-the-highway discussions here. I think people need to realize that their own mission is not going to be everyone else's mission, and keep in mind that each aircraft type has its strengths and weaknesses.
