The FT model is pretty good, but they get away with just a straight profile by keeping it very small and slow. For a more traditional parkjet size you'd end up with something pretty close to SGTalon's with more CF, etc.

This is the problem ... Enterprise has those weak pylons to take the nacelles .... plus that big dish.

The FT model at least has a reasonable amount of body to it in the rear to try and leave some strength .... I think laminated sheet will give strength ... a horizontal spar across that rear part ... maybe a cf spar from nacelle down at angle to centre each side to brace them.

Just downloaded 3 views of D version similar to FT's .......

Starting to knock up a few sketches ....

Trying to keep concept but also to simplify build. After checking out various 3d views of the D version - it became possible to think about a 'body' to the main part under the dish ... hopefully enough to be able to carry Rx and ESC ... I think battery is going to be up front though unless it is a tractor prop.

FT altered theirs to have elevators on the nacelles .... I think I will go for the rear of the dish to have elevons ...

Working on ratios .... note the numbers showing dimensions are not cm or inches ... they are units to show the ratio against each other. For the size you want - just multiply each number by same factor ... for me I'm aiming for 1.5x .....

That makes dish 570 x 450mm - a reasonable size I think.

Yeah, adding some width and depth to the flat pieces will probably help the strength a lot. If you look at pictures of the Enterprise D the junction between the saucer and the main body is pretty sizable actually.

think the big issue you will have is CoG...same as the SGTalon designs. I'd add a bit of diehedral to the saucer section to promote a bit of stability. Basically build a nut ball and add the nacelles. Keeping the rudder servo(s) off the nacelles will be tough. Good luck!
