Status: online 		Cp,

I have an alternate suggestion for the postal-ization of your twin. First paint the fuselage glossy white and include a permanent Sharpie (tm) marker in the box. Then everyone who flies it performs one of my favorite (and most practiced) maneuvers, The split, reverse, immelman, lomchavec (yeah, yeah you look it up), inverted, figure nine. The pilot then carefully, before removing the craft from the ground, the line of maximum penetration. Only one attempt per pilot. Then as the model slowly works its way around the planet, science would have a valuable record of the relative hardness of our flying sites AND the pilot who has accomplished the deepest penetration (oh I blush when I write that word) would not only have the admiration of the rest of us mere model airplane players-with, but a suitable trophy could be displayed in the Smithsonian Garber Facility (or whatever they call it now).

But think of it, dear CP, you would have been the inspiration of a scientific accomplishment that would resound in the academic world for its daring and innovation. One small plane for a man, one giant step for penetration (oh there I go again). Applause, applause.

maybe CP should go with carbon over glass,
over kevlar mat, around Tungsten Rod,
and sell it to the military for Anti-Tank work.

.... but the military would probably have to slow it down from CPs standards for 1/2A planes

Status: offline 		KE, I've been calling this fuselage "ornamental drag and ballast" everytime I look at it. It might work OK in outer space, but down here this plane will top out at 80 mph with a belly full of lead and thrown off the Empire State Bldg, no matter how much power I try to throw at it. The decision whether to power it for climbing ability with the .074s or try for speed with the AMEs is still up in the air.....
It seems to be a cruel fact that futuristic & small "prop-jet" models have to be slower than plain jane conventional types.

The real challenge is to come up with a facsimile of the real deal that flies OK as a model. Hopefully this one flys long enough to gather enough info to try a scaled up version. I've got a bunch of 31 cc Ryobis laying around doing nothing.

Raymond, I like your penetration idea, we should see if there is any grant money out there for this kind of research.

Perhaps someone else could design a plane that this one could dock with? Have a scoring system for successful dockings and extra style points for torque rolls after insertion and stuff like that? Of course attempting to dock before the judges blow the horn would be known as premature dockulation. Maybe even form a SIG for this event and petition AMA to sponsor a new category at the Nats?

or getting someone to fly a Flattop Derrigible for carrier landings while at altitude?

Status: offline 		Are those holes at the rear of the nacelles for mounting a pair of F rocket motors?
Or am I thinking too far outside the box again

Maybe a 30mm computer chip fan, just enough blow to act as a DragBuster at the back of the nacelle

The engines look to be the .074's so my guess is the openings at the back of the nacelles are for the two .061 AME's I sent him. Piggy probably needed the weight to get the thing to balance. If you have to add weight it might as well earn its keep

Status: offline 		I like all those ideas. You know, if you spend X amount of $$ on the lightest and best materials to build a model plane, then have to use lead to make it flyable, then the design is a failure. All ballast on this sucker will be functional, even if it has to be in the form of electric motors in back.

Status: offline 		Too Cool CP. Now to make it really interesting with that long nose sticking out there, you should slap on a servo powered canard. Talk about some interesting aerobatic possibilities! Hehe. Sorry...couldn't resist....I think it will likely be interesting enough as is. Keep up the good work!

No problem, of course the most important feature is an open cockpit . You could use plush combing, or smooth leather if you prefer it that way (I do). The owner should make sure the upholstery is always clean. Of course you'll be buying fresh fuel regularly (the best stuff) despite the fact it has hardly used the last can at all, new props every time you get the tiniest mark on the old one, and keeping an assortment of glow plugs on hand even though the old one looks fine to you and works well enough. Oh and don't forget the latest in over-priced perfumed after-run oils. One down side is that you only get to fly three weeks out of the month, and just before the week off you need to smile a lot, stay quiet and agree with everything it does.

Or if you sing in a different choir, just get it up to top speed and ram it stright into the tail section of the first cute trainer you see. Docking guaranteed, ready or not.

Status: offline 		I really like the idea of two Estes F motors in the back of the nacelles wired and ready to light off after take off and throttling back. Out of sight vertical, for sure! Oh... and come on, ditch that nose and build a flying wing -- make the ghosts of the Horten brothers smile!

Status: offline 		Well, there are nothing but compromises to make all the time, that's why I don't bother drawing anything up [except a rough layout] until after it's built, saves on erasers. To keep the rudder linkage concealed, it will be hogging the room in the back of the nacelles that the rocket motors should have. The "exhaust nozzles" are actually access to the elevon and rudder linkage. The rudders will be the hardest part to get right, especially with matching tilts. I can't wait to get done enough to start shaping some wood.

Status: offline 		More hackin' and hewin'. The wiring is done, tedious little stuff. Now the next step is getting the nacelles shaped and get the rudders mounted and hooked up. I hope those .074s will put out enough thrust for strong launches, this plane would be hard to throw. It might take a high start if the thrust isn't there. I figure the plane will weigh about 2 pounds RTF.

I wouldn't want to get too involved with the rudders though until
it gets some speed built up
