Hey guy's,

When designing a twin boom aircraft, what can be expected in performance in horizontal (perpendicular to the fuse ) area
vs lateral (in line with the fuse and between the booms ) area?

I understand that an area close to 25% of the wing area is required on conventional aircraft, but if the area between the booms stays with this theory, will the aircraft retain stability?

Lets say the distance between the booms is fairly narrow,
12 3/4". The wing span is approximately 68". Will extending the area between the booms in a lateral direction give any additional stability if you extend it to the 25% mark in relation to the wing area? This would also include the area of the elevator.

I am in the process of building a turbine powered model of a flying car. I have built and successfully flown several pusher prop versions and a ducted fan version of this aircraft .

I have flown one with no over hang on the stab, but it needed a gyro for pitch stability.....I will try to attach some pictures.

Thanks
