I have completed the GP AT6. Now I am waiting for it to stop raining so I can fly it....
The AT-6 was fairly easy to assemble, but it is very heavy. I had to put 4 - 5 oz lead in the tail to get it to balance with a MDS .48 in the nose with a Bison Pitts muffler. I moved the battery as far back as it would go and used the lightest pitts muffler I could find and a light aluminum spinner nut and still had to put 4 oz of lead in the tail. I am not sure how some people have these come out tail heavy. Maybe the quality of the ARF? I have become increasingly unimpressed with Great Planes ARFs. The quality is just not there. I went with the retract setup instead of the fixed gear and that took a great deal of time to get right. I can explain how I did it if you are interested. I will let you know how it flys if I can ever get back to the field.
