Jeff,
I began designing a large (>100") turbine powered Jaguar about 5 years ago. The drawings were about 1/2 done when life got in the way and everything has been sitting in the closet ever since. I will be getting re-started on this project in the next month or two and it sounds like you might be able to answer some questions I still have about my design.
Q#1.
The full scale Jaguar has a significant amount of down thrust in exhaust nozzles (around 4-5 degrees). Did your model have down thrust in the exhaust? and if so, how much?
Q#2.
Roll control. Did you use spoilers and tailerons (like the full scale), or did you install ailerons.
I am hoping to use tailerons and spoilers for mine, but the complexity (and limited space in the tail cone) may preclude this.
I absolutely love the look of the Jag, and think it will make a great model. If you have any suggestions or warnings I would really like to learn from your experience.
Thanks,
