Default Cherokee 235 vs Trinidad vs Comanche

As others have pointed out, between a Cherokee 235/Dakota and a Comanche
260
you are really talking about two different classes of performance. The
primary difference is that the RG of the Comanche gives a big boost in
cruise speed and a smaller boost in climb rate from engines of comparable
power.


Understood--see my response to an earlier post, I understand the Pathfinder
is odd-man-out in the group I list. I include it as the only fixed-gear
that appears to fit my mission description.

As to the differences you cite, I definitely like the speed boost, and even
a modest boost in climb rate is important at my higher operating altitudes.
I'm investigating the Pathfinder primarily for cost reasons--on my first
time out, I'd hate to ignore any viable candidate, so if the 235 can do what
I need for less money, it will be a real contender that I would have to
consider.

[snipped good discussion & comparison of various a/c]


If I were based at Colorado Springs I'd certainly consider a turbocharged
airplane, particularly if much of my flying took me west over the Front
Range.


Considered, definitely. Turbo scares me--too many horror stories, both of
overtaxed engines and monster (even by GA standards) maintenance costs. I
don't expect "much" flying over the mountains, but who knows? In theory, I
agree with you; in practice, I think I'll shy away from turbo my first time
out. Trying to "beat" this issue w/ normal aspiration is a large part of
why the Comanche and Trinidad are on the list, btw: their 20K' ceilings.
I've been told the real-world ceiling of the Comanche is more like 17K'
(which still beats the "book" numbers of the others you cite), and the
Trinidad apparently really is capable of FL200.

Thanks, Elliott--great discussion. Dunno if you recall, but you helped me a
great deal when I was first starting here, in particular with understanding
the tradeoffs between fixed gear and retracts. Then and now, I appreciate
it!
