I was well over my addiction to C421's and had stopped gawking at them on Controller for nearly a year and now this darned thread has me lusting for them again. Man they are awesome birds. I wish I could buy 25-50 hrs time / yr on a nice one. Yep, Sell your 3 planes & buy a C-421. At least now you know you don't need to spend 5 figures on maintenance ad nauseum

340 has lots of storage, but not as much as 414 or 421. In the nose, I usually load a full-size rolling garment bag, 2 roller-board style bags, a duffle (gym-bag) bag, and a beach-style bag. smaller bags help it go in easier.
in the wing locker, I carry a military style helmet-bag that has my wife's espresso machine, grinder, and milk frother (don't even ask). there's also a full set of tools (I guess you need them in a 37 year old twin), window covers (or a Bruce's cover- depends on the mission), spare oil, and a refueling mat. room to spare.
there's also space behind the pilot's seat for at least 2 duffle bags, and an aft-cabin baggage shelf.
space is never an issue.

You don't mind quality cheap but you don't get on time when you get involved in your own maintenance. You spending time sourcing parts, making decisions, etc. It always delays the final product. When my living depended on flying 3 days a week on tight schedule, all I cared about was quality and on time: annual starts on Monday, get finished by next Monday. I didn't care about overnight charges for shipping. Shops like the one above can deliver that. You cannot do that on the cheap.
Sorry, thread resurrection, because I started one myself not finding this one in a search (although arguably, if I run a couple searches and can't find what I need in the first couple pages of each search, I'll just start a new thread). I am involved in my own maintenance. I most certainly understand quality and on time. For the rest, that's absolutely right, but many of us don't depend on our planes for a living don't care if it takes a little longer. It doesn't mean we don't understand it. I've been flying for a living for 25 years, licensed for 30, worked Corporate, Charter, now airlines; pistons, turboprops, jets, been there done that. I understand it just fine. I don't NEED it on my personal plane. I'd rather save the AMU's. My Baron will be in the shop going on 30 days - I presently don't care because I'm nursing a shoulder post-op. But even when I'm flying, I don't mind waiting a week to save $1,000 on a part when it's coming out of my pocket and the plane doesn't generate revenue as it is. Both my 530w and Trig had to come out for software update to talk to each other for ADS-B. I pulled them myself, drove down to Avionics, had lunch with a buddy. Came back a week later, picked said radios up, put them back in myself, shop charged 0.5 to diagnose issue and check installation of radios and make logbook entry. Saved 2 hours of labor and shipping charges. We just found a big hole in the left front induction tube because that's where I told the shop to go look when they wanted to start pulling jugs (thanks to BT!). Now I'm getting a serviceable used induction tube off an identical engine cheap and saving buying a $1,500 part from Beechcraft plus about a couple days of labor. When it comes time to annual I'll spend a day of my time pulling all the panels and putting them back on when done and helping set up jacks, etc, because it's my day off and I like doing it. I'll also save $1,000 on the annual doing it. Owner involved maintenance can save thousands of dollars for people who aren't needing an asset to generate revenue. I get where you're coming from, but don't knock the people who are in a different boat.

The 340, 414, and 421 have the same systems and MX. The overall cost is slightly more for the 421.
My Ram VII “direct operating cost” was 500 and hour based on 100 hours per year. My 421C direct operating cost is 600 per hour based on 100 hours per year.
My 421 annuals including parts average 12,000 per year. A VERY EXPERIENCED owner can perform a lot MX on a 340, 414 and 421.
I just replaced everything FF with factory new engines, turbo system, engine mounts, Exhaust, props , hoses etc. 17,000 at 75% TAS 220kts.

I’d be interested too - I’m getting closer also.
What’s your thinking for factory new? Guaranteed new cases or more than that?
Cheers, brad.

That’s 155k Aus - plus freight. Thanks for letting me know. Does that include installation costs?
