Hello to one and all.
I suppose I'm the new guy in the hangar but an old guy at the airport. I have been doodling around for about a year now and happened to run into this site when I figured there was enough merit in my design to take it to a serious group for some advice and guidance.
I am interested in designing a personal light sport aircraft that will be profiled as a fighter plane and so far everything I have done looks pretty good. In finalizing weight and CG studies, I came across a problem that threw the whole design into a tail spin.
The design began as a single seat fighter and I figured, ahhh, let me get a tandem pilot in there so he can watch my six while I'm on the enemies six.:grin:
Then it happened. I could not for the life of me figure out any way to get the static margin to stay within limits with the extra pilot and instruments in place. That percent went from a balanced and relaxed 16.5% to a "hair raising aerobatic, keep your **** hand on the stick" 6.4% percent.
I will share all my work with the community as soon as I learn how to do so, but until that time, and hopefully I will be here for a while, has anyone been able to work out that little proble with the static margin in tandem? The design is in tractor configuration.
Thanks
John
