OK, guys, let me clarify this thread a bit. I am not attempting to set up an airplane. We have another member running a thread concurrently to this one in which he is attempting to determine what size engine to run on an airplane. He has an old Stick that weighs over eight pounds and he has to put 12 ounces of weight in the nose to get the CG in the correct place. Well, eight pounds seems way too heavy for a .40 size Stick with a 58 inch wingspan. With his having to add 3/4 lb. of weight to the nose, I was assuming it was tail heavy so I was attempting to find out just how much weight was actually on the tail wheel. I'm GUESSING that it should not be over 20% of the total weight of the plane which in this case would be about 1.6 lbs IF 20% is a valid number. Then I find out it is a tricycle gear. Blew my thought process all to hell. It still seems to me that there should be a range of total weight that should be on a tail wheel.
