RE: THE NEW CERMARK F-16 BUILD IT BETTER, STRONGER, AND FASTER!!!
My CG was by the book at 8.75-9. I think this is tail hevey. I think 8 - 8.25 should be about right. I added weight to to tail. I took about 10 Oz out of the tail and balanced at about 8. I will try another flight as soon as I can get some free time. What CG are you useing?
