My first idea was for a 70" wing with a 13" Chord and a T-tail, but has slowly been changed to it's current design of a 75" Wing with a 12" chord and a normal tail.

Here is a video of the designs

Thanks for reading this post and be looking out for more information on this plane!

I probably will not do any bomb drops or fpv until I get the plane flying good and I'm confident it can carry the extra weight. I may just mount a camera to record video but not fpv.

Mock-Up built

So I have built a mockup of the plane to its full size. This one will not fly, but it is good to see how it all fits together and what I should change before continuing with the actual plane. After building this I have decided to double the foam on the vertical and horizontal stabilizers and change the way the motor pods are mounted.
