This is a great thread. I agree with the longer tail moment. I have found for my flying that I like a ratio of 1 inch ahead of the CG for every 3 inches behind the CG. I set the CG at 33% of the wing cord behind the leading edge of the wing. I prefer a constant wing thickness but tapered trailing edge and square leading edge.

One thing that I have found to be a great help in my balancing is to build the fuse thick enough to house the battery pack and receiver. This also greatly simplifies another feature that I really like which is removable wings. I put an access hatch in one side of the fuse and thereby can move the battery for and aft to adjust the CG very easily. I use padding to hold everything in place. Then when I go to the field, if I want to move the cg, it is as easy as removing the hatch and sliding things around.

I have even built a stand off scale profile Decathlon with 2 piece removable wing. The wing is nearly 6 feet long and runs an Evo 1.00. Plane weight 5lbs 7 oz all up and wet. 71!QUOT! wing span and 14!QUOT! chord. 12 ounces per sq ft wing loading. You would be surprised how well this high wing design flat spins and how well it harriers. I have been able to fly a stable harrier for 4 laps around the field and drag the tail for about 200 feet down the runway. .

Keep the information and ideas coming guys, I live to design and build profiles.
