Default twin boom help

Im looking into building a twin boom pusher. Id like to put some numbers forth in an effort to save a few crashes and disappointment.

wing span.....32"
root chord.....8"
tip chord......6"
sweep.........2"


stab root chord 4"
stab tip chord...4"
stab sweep.....0"
stab span.......12"

distance between l/e's 20"

im looking at about 16-24 oz all up

I plan to use a fullflying tail with a pivot 1" from the l/e to the center line of the pivot.

I plan to use a pull pull setup on the tail and rudders......maybe even the ailerons if I can figure it out.

Im putting a speed 400 from Jeff and a 3s lipo on this.

So.....hows these numbers look?

Other than appearing a bit smallish wing area wise... OK.
I'd go for 36" span.
Done a few twin-booms... but using 2M wings for larger airplanes overall.
The booms have to be stiff to resist bending.
There's a lot of download on the horizontal which can bend the booms down with increasing airspeed, which will force the plane into a dive.
Lost the third in the photos that way.

I like the wierd V-tail.....whats that called Sparky?

I got a good start on things. I had a hard day today, and barely had a chance to fly.

I went with a 36" wing.
