Hi guys,
When you mount the engine on the wing using a nacelle does this effect the lifting properties of the wing? Does it effect the MAC math? What are the drawbacks of the regarding a tractor type setup for engine on a wing is what I am asking?
I would prefer this type of setup over the pusher type of setup, I normally see used on a canard.

You might describe the plane better... is it a wing-tail airplane, or a flying wing?
I see lots of canards with pusher motors at the rear of the wing..
A tractor motor on a canard is rare.
".. a nacelle..".. ?
Nacelles are generally used with twins.
And have no effect on the geometry

Paul you are right nacelles are used with twins.

what I have in mind is basicly you standard canard, but using twin motors on the wing. I did not want to use the tractor set up up front because that would direct air over the canard and would keep the canard from stalling before the main wing. Also the weight in the tail construction of most pushers does not seem to me to be all that good of an idea. I was thinking that if I located the engines/motors on the wing I could bring more of the mass toward the MAC which I think should improve the over all performance of the aircraft, or am I wrong about that. the other thought was to install the vertical stabs and rudders at the back of each nacell to provide more rudder control which seems to be an issue with any canard I have seen. And yes I am aware of the issues involved with a twin or multi engine hence the vectored thrust idea with the rudders....

Iron, something like this?
It would probably work OK.
Do a 18" or so chuck glider to get a feel for where the c.g. should be.

Paul,
You have read my mind....
Nice drawing, I was thinking of blending the body a bit more but you have it real close...

Paul, yer a Gen-u-wine Arteest! As it sits it's pretty slick.

I can almost see it as a Crimson Skies aircravt if the fins were downward facing and a cockpit and gun barrels added to the nose along with a racy looking paint scheme.

It's just a sketch..
I'd never build one... too many fragile parts at the front on a canard.
The Starship doesn't have a lot of vertical area.. I suppose some of it comes from the props.

Thanks Tall Paul,
Keep you eye on the scratch build forum this fall and winter I am going to post about the design and build. I have decided that this will be my winter project, I know this is going to be a handfull. At the same time I think that it is posible to make a canard aircraft that can fly very well. And a bit of carbon fiber can go a long way to take some of the fragile out of those nose components.
Oh well of to finish another plane for my wife....
She wants it for the weekend.

Iron Eagle,

You mean like this one?

This is my original StarLiner Mk III. I removed the .45 glow pusher and stuck on 2 AXi 2814-12 motors running 3s Lipoly on 9x6 APC e props. 6 lbs ready to fly and it goes like mad!

Chuck, a top view with the c.g. please.. please...

Ask and you shall receive...

Attached is a top view with the basic dimensions and the CG, a section of the plans showing the twin mounts, and a couple of pics of the plane. I have not finished the plans for the twin yet, getting all my StarLiner plans ready for sale.

As to differences in flight between the single pusher and the twin, both versions fly virtually identical. The only "difference" I have found, is the noise the props make during high "G" manuvers, they rumble a bit from the turbulence off of the canard when the elevator is at full deflection in a high "G turn. The turbulence doesn't hurt anything, just makes a bit of noise.

Now about that twin EDF version..........

Thank you!
I put two motors on one of my vee-tail planes which had used a single motor pushing between the vees. The vees would shake a lot when turning due to the prop blast.

Chuck,
I am still going to build the StarLiner stock, (my foul weather project this summer).

I had started on some sketches of a twin engine canard using a 80 inch swept main wing, thinking about using vectored thrust to get some good rudder at low speed. It funny you mentioned a twin edf version I have been tossing that idea about for a few days now, seems like something that has to be done. Hmm, vectored thrust for rudder, and ailerons, may be an interesting variant to your design.
I had started on a totaly new design for a canard but why reinvent the wheel you have already tried the twin version so I will start with you basic design. I will be sure to send you some drawings and pics as it comes to life.
My winter building schedule became side tracked when my wife decided to take up RC this fall, (building and fixing trainers for her, no big deal I love to build airplanes) but it slowed my work on my planes.
