The Blue Tail Jet, for lack of a better name, has been in my "In progress" file for some time due to "lack of progress" . Finally got this design to fly and could be a good park flier design. Could have changed the fins and wings to make it a bit more stable but decided to stick with the 50's jet age look. The rear transition moves the wieght of the engine aft and really degrades the static margin on such a short rocket.

Enjoy and Thanks Again, JP

That's part of the problem I have had. I want something other than 4FNC and it isn't very stable. Go figure...

It's a problem we all suffer with age. Our margins degrade as our weight shifts to the rear...
