    Why specifically do you want a twin boom pusher?

    becuase i need a non-canard pusher design that leaves me either twin boom pusher or mid engine pusher. issues with mid engine configuration has scared me away (difficulty with engine installation and cooling, pitch sensitivity). single boom pusher can also do but they are very rare as i can see it.

    Re: twin boom pusher plans

    What do you mean by "mid engine"? Engine over the wing, like the Kolbs? They're single boom pushers...

    But what are your other requirements? Fast, slow, number of seats, range, etc.?

    I think he's talking about something similar to Gray's project, you know engine in the middle of the plane.

    What's wrong with canard pushers, Berkut with 200 HP engine, has a top speed above 200 kts, range 2000nm with aux tanks.

    Difficulties with engine instalation?
    It's for sure harder task than a "conventional" design, but it isn't impossible. Who said that designing, buliding planes is easy.

    Cooling?
    It's easier to use water cooled engine, than air-cooled. Everything what you need is a proper radiator under belly, similar to Mick Long Ez. (attachment 1, 2)

    Of course you need to do some calculations and tests/experiments.

    Er, Cheetah650;

    have you looked at the American PatriotII aircraft? I don't know if they offer plans, however, their aircraft is definitely a twin-boom. See: American Patriot Aircraft :: Home

    Fly safe,

    Thanks Malcolm - I hadn't seen that one before. I'll add that to my collection.

    As far as I know, the T-100D is the only twin boom pusher that's currently available as plans-built. I'd love to be wrong since I really like the look - and it makes it soooo much easier to pretend I'm flying a P-38 My favorite design is the ION (Ion Aircraft), but their plan is to only sell it as a kit and, based on the "completeness" of the planned kit, I'm currently assuming that it's way out of my budget league Still drooling, though.

    To cheetah650: I would wonder, though... What is the "flying mission" for which you want a twin-boom pusher?

    Don't forget the option of a boomless, tailless pusher! 'course, there don't seem to be many of those out there yet. :-D

    While I absolutely agree that the ION is a neat, pretty airplane, that project seems to be grinding to a halt over the last year or so. Web updates are less frequent and less positive - and more vague - and I read about them doing some rather major redesign work. New wing?

    From the point of view of an outside spectator, they have the appearance of a group that "can't let go of the design", and will keep tweaking it endlessly until their money runs out. I may be 100% wrong in that, but they had first flight going on two years ago, and still haven't started setting up the manufacturing, customer support, and marketing areas of their business. In other words, they've got about twenty percent of the work in setting up their business actually done, in the form of a flying airplane.

    I wish them well. The market could use some new blood.

    More vague? Less frequent? That's possible?

    I hadn't heard about any redesign work or a new wing...they are switching engines, though (for the third? time) I'd be curious to hear more about them (here or pm or new thread or whatever). The only "news" I ever see is from the Yahoo! group... and it's always from one guy... and he's never very talkative. As far as I know, the wing structure hasn't changed. It's still an aluminum wing, but bonded instead of riveted.

    My fear with them has always been that they'd get a prototype (or two) flying, sell some kits (somewhere between 5 and 50), and then fold for any one of a hundred different reasons (new "51% rule", too many LSA designs, ran out of money, couldn't build kits quickly enough, etc.). They've done a lot of work and it seems like the design is solid, so it would be a shame to see the design die... but I'm not confident that they'll still have a viable business by the time I have enough cash saved up to do anything.

    Re: twin boom pusher plans

    Check their website. The new wing is (passingly) mentioned in the September 2008 update.

    And yes, I share your concerns. They've got a neat product, to all appearances, but are being rather typical engineers in that they seem to be tweaking it over and over again, and not settling down to the process of actually starting the company. That's a huge project in and of itself. Probably as massive, overall, as designing the aircraft and building the prototype.

    Ahhh $#!+ Now I see it. I remember that, at the time, Steve was going on and on about wing-tips. So I probably skimmed over it and saw "new wing tips" instead of "new wings."

    Now I'm really bummed : Maybe someday I'll get to see the prototype fly...
