Pike Perfect Fuselage and elevator. The tail boom is approximately 30 inches long from the back of the wing saddle to the front of the elevator. Behind the wing saddle it is oval - about 50X35mm and at the front of the elevator it is close to round with a diameter of 25-27mm.

Sorry it took a couple of days to get the photos, my daughter has my digital camera so I had to resort to my iphone...(took me a day or so to think of that since I was waiting for my camera back.)
