Here are my requirements (which are actually less that what I currently have): Twin engine, with a single engine absolute ceiling at gross not less than 5000 ft (not negotiable - not interested in singles) 150 kts cruise at low altitudes (less than 8000 ft) at less than 65% power (don't like running the engines hard) and less than 18 gph (don't like spending money either). Must be able to burn either Avgas or Jet-A (no special fueling issues). Note that this is a bare minimum - my spam can does better in every respect. Does it burn coal and natural gas too 5 hours endurance at 150 kts (including climb fuel and VFR reserves). Enough useful load to carry the fuel required for that endurance and an additional 600 lbs of pax/cargo as well as a full redundant IFR panel (dual nav-coms, dual AI's, GPS and LORAN, stormscope, autopilot, ADF, DME, etc). Again, these are bare minima. Cabin room for full size adults (think Bonanza and up - not Mooney). Not interested in building - will only buy one that is already built and flying. No one-offs - only want a design with enough track record to be insurable for hull (I will take whatever training and meet whatever experience requirements they want). I'm looking forward to your suggestions. Michael I guess I was Wrong I can't think of a single homebuilt that is worthy of you. What kind of magic carpet are you flying? |

Enough useful load to carry the fuel required for that endurance and an additional 600 lbs of pax/cargo as well as a full redundant IFR panel You said 4 full size adults. Today that is 4 X 170 = 680# (if you are lucky to find 4 trim adults) plus at least 20# each for baggage makes 760# after fuel. At 9 GPH at 65% you are pretty much talking 4 cylinder engines. Even an IO-470N will run about 12 GPH at 65%. But figuring your optimistic 18 GPH @ 5 hours plus a half hour reserve = 99 gallons useable so figure at least 110 to 120 gallons @ 6#/gal = 660 to 720# plus 760# for pax and baggage means about 1500# useful load. The hard part is going to be getting it all together. The hardest part is the speed at 65% at low altitude loaded and that fuel burn. (dual nav-coms, dual AI's, GPS and LORAN, stormscope, autopilot, ADF, DME, etc). Again, these are bare minima. Cabin room for full size adults (think Bonanza and up - not Mooney). Now you are talking bigger engines and more fuel burn which means long range tanks in something like a Baron. According to the specs the Aztec will do it all except for the fuel burn. At 65% you are still looking at least at 22 to 24 GPH, but they are docile and the panel can always be upgraded. Anything smaller has miserable single engine performance. I can't think of any recent/new small twin that can match the Aztec for useful load and it comes the closest to your specs. Anything newer that I can remember will burn a lot of fuel to meet your specs. Get the Geronimo conversion, put 70 grand into a new panel...well maybe 80 grand and you'll have your machine...except for the fuel burn and easy to find parts.

Then we'll agree to disagree. I think 65% or less and LOP is the way to go. 1500+ hours, and only replaced 1 of 8 jugs. You said 4 full size adults. Today that is 4 X 170 = 680# (if you are lucky to find 4 trim adults) plus at least 20# each for baggage makes 760# after fuel. A plane that can put full size adults in every seat and still fill the tanks has tanks that are too small. My normal mission is 2 full sized adults, bags, and full fuel for long range flight. My alternate mission is 3-4 adults, light baggage, short range. I adjust fuel load accordingly. My normal launch states are full tanks (allowing me 600+ lbs of payload and a 5 hour endurance) and mains only (allowing me 800 lbs of payload and 3 hour endurance). At 9 GPH at 65% you are pretty much talking 4 cylinder engines. Even an IO-470N will run about 12 GPH at 65%. No argument. Both my certified choices feature small fours. But figuring your optimistic 18 GPH @ 5 hours plus a half hour reserve = 99 gallons useable so figure at least 110 to 120 gallons @ 6#/gal = 660 to 720# plus 760# for pax and baggage means about 1500# useful load. Remember I said my plane does better in all respects. For me, 150 kts happens at 15 gph at 8000, so my 90 gallon load is plenty. Also given that with full fuel I only need to carry 2 adults and bags, we're down to about 1200 lbs useful load. But of course with less efficient airframe/bigger engines it might need to be more. The hard part is going to be getting it all together. The hardest part is the speed at 65% at low altitude loaded and that fuel burn. Not hard at all. There are two certified twins that meet my requiremens, and either can be had in very good condition for less than $100K. Those twins are the Beech Travel-Air and the Piper Twin Comanche. The Twin Comanche is somewhat more efficient and has cheaper parts, but is more demanding to fly. Anything smaller has miserable single engine performance. I only need a 5000 ft absolute ceiling on one engine at gross - my flying is almost all in the lowlands. Therefore, I am not concerned about the miserable single engine performance. Actually, when you compare light twins at full gross, they all do just about the same until you get into the cabin class. Get the Geronimo conversion, put 70 grand into a new panel...well maybe 80 grand and you'll have your machine...except for the fuel burn and easy to find parts. I already have my machine - and it meets all my specs and then some. Unfortunately, it is certified. If I could have an experimental I could buy (not build) to meet those specs, I would pay up to 50% more up front to buy it than I paid for the certified airplane. Unfortunately, it's not there at any price. Michael |

I guess I was Wrong I can't think of a single homebuilt that is worthy
of you. You know, I find it amazing that proponents of homebuilts seem to get defensive when you point out that the homebuilt is not the be-all and end-all. It's not a matter of being worthy, it's a matter of meeting mission requirements. In this case I can't find a homenuilt to meet my mission requirements. I'm not against homebuilts. In fact, I own and fly a homebuilt glider (HP-11T). I love it. It gives me performance that no certified glider can match at anything less than twice the price. It meets my mission requirements and saves me money and hassle. If I could find a homebuilt to meet the mission requirements of my twin (long range, overwater, night&IFR) I would own it. I hate dealing with the FAA any time I want to upgrade, and I hate being locked into obsolete and expensive parts. But there's nothing out there. I've looked before. I would have been genuinely happy if you found something I had missed the first time around. I would have bought it. If someone comes up with something that meets those requirements (I might even bend on the insurable-for-hull bit) I'll write him a check for $100K tomorrow. That is substantially more than I have in my existing twin. What kind of magic carpet are you flying? I'm flying a Twin Comanche, but a Beech Travel-Air would also work for me. Michael |

I can put 4 full sized adults and full fuel, and still have over 500 pounds left for baggage! All this and I can fly 6 hours without stopping! The 235 is a wonderful plane....and a 182 can do it too, among many others. z |

Think about it. ^^^^^^^^^ Sounds like you need to go back to grammar school and learn how to write. Just as outlawing abortion will hapen when Republican legislators no longer have teenage daughters, effective tort reform will happen when Republican administrations and legislators can do without highly motivated attorneys-the kind who play for blood more than money. You poor brainwashed fool. It's the bloody trial lawyers giving all that money to Democrats (www.opensecrets.org/orgs/list.asp?order=A) that's holding up tort reform as much as anything. The tripe emanating from your fingers in every post you've made in this thread is a modern-day version of the big lie. Like nobody has ever done in any of the rec.aviation.* newsgroups, you really do make me want to puke. Sorry to say, but people like you epitomize so much of what is bad about this country.

I can put 4 full sized adults and full fuel, and still have over 500 pounds left for baggage! All this and I can fly 6 hours without stopping! VFR. Now try flying when the weather is widespread IFR with an iffy forecast. Your nearest solid gold alternate might be 2+ hours away - and all of a sudden, when it's just you and maybe one other guy in the plane, you start wishing you could carry more fuel. Or maybe you wouldn't but I know I would. More than once I've had to make an extra fuel stop I really didn't want to make not because I couldn't make my destination but because I didn't have enough reserve fuel to miss at my destination and then make an alternate I was sure of. Of course I suppose this is the sort of attitude that might lead others to believe I should never fly anything but a kerosene-burner with a crew, but to me it just seems like a reasonable plan for staying alive while flying in crappy weather. The 235 is a wonderful plane....and a 182 can do it too, among many others. Actually, I like both of those planes - but there are at least a few people who agree with me that the tanks are sometimes too small, since extended range tanks are available for both. Remember - just because the tanks are there does NOT mean you have to fill them for every flight. On my airplane you can fill every seat with a full sized adult and carry bags and still make 500 mile legs with reserves - but not by filling all the tanks. Michael |

![]() "Denny" wrote in message ups.com... Of course, a big ticket manufacturer is in a different ball game... Non the less, if more businesse in the Untied States were structured so that there are no deep pockets to go after, there would be a marked diminishment in frivolous suits, including against the big guys... It could be solved just as easily by changing the law as it is in the U.K. Loser Pays. There are attorneys who make a career out of looking for deep pockets to sue - for a huge chunk of the judgement of course - knowing that they will lose 9 suits out of every 10... But, that tenth suit is like winning the lottery, Christmas, and having your rich uncle leave you everything, all rolled into one... If the first nine deep pockets aren't there the tenth suit is going to be fewer and farther between... Grin right back at ya... Denny California just had a ballot initiative to get rid of a law that the hippies in Sacramento wouldn't repeal. It allowed lawyers to on behalf of the public, while all they really did was line their own pockets. One firm, The Trevor Law Group was put out of business and it's lawyers disbarred because of the way they used this law to go after small businesses and threaten them with a law suit for some minor infraction or other. Is it any wonder so many politicians are lawyers and that the Trial Lawyers are such big contributors to the Democrats? |
