441CR looks pretty nice. 2 new windscreens, electric torque, and fresh hots. That right there is like $125K worth of work.
Jeff R, didn't you call about this one?

True, but the same applies to almost all piston twins. When I am at GW I use long runways with few obstacles in the direction of the departure. Once I get past 1,000 feet AGL I can turn around and return in most cases. 90% of the time I am under GW with 2 to 4 people and baggage. There is nothing better than two well maintained engines and in 1,243 take off’s and landings I have not had and engine failure but I always plan for it.
Very few twin accidents are caused from losing and engine on take off. Most twin accidents ( including turbines) are in other phases of flight.

It's disappointing that we've turned this thread into a 421 v 425 thread, so let me state this first: there is no doubt that the 425 is a superior airplane! More HP always makes for a better plane, and that's one reason why the 425 is better than the 421 and the 421 is better than the 414 (and the T28 vs the T6 . However, sorry Rick, but I can't stand by idly while the 421 is bashed. Mine also has just under 1200 lbs available when the mains are filled. The VGs only ad 129lbs of payload, so not a huge increase. From experience, the plane handles quite well at max gross and climbs easily to the low 20s. It also handles very well on one engine with no drama, even when heavy. Would I rather have turbines with auto feather on takeoff? Sure. Who wouldn't?! However, if you're going to burn AvGas, the 421 is damn hard to beat. Robert

I agree Robert, and have a sincere appreciation for 414A/421 design having owned one a few years. I loved flying my 414A, and was amazed how comfortable life was flying that plane. I would never knock either plane if it works for your mission. Kudos to Cessna for making it happen - they really did an impressive job engineering these birds.

Quote: At sea level and gross weight the SE ROC is about the same for the 425 and 421. 350 and 357 FPM According to my book anyway, the 425 OEI ROC is 390 fpm @ max gross @ SL @ ISA+0 and 220 fpm @ 6000' @ max gross @ ISA+26 (30 deg C)

Can a potential buyer expect to have a long wait or are off-market deals more common compared to its piston brethren? Anyone know if this plane is one of the phony ones? Or a sub-standard example? https://www.controller.com/listings/air ... conquest-i
Definitely check for your self but I believe I remember there were 2 of them from that broker that when we called, they said they didn't have any Conquests available. Not 100% that was one of them though. Pisses me off when they try to do the bait and hook.

Quote: A stock C90 has less climb performance. Doesn't a C90 GT have the same HP rating as earlier models with the -21 engines? If so, then why would it have better performance at sea level? A -21 airplane and a -135 airplane should have the same performance until the -21 temps out and the -135 is still able to make full torque.
