I am using an 8–ounce tank. The fuselage is 3-inches wide so there is plenty of room for your tank and controls. To balance mine I had to place the battery at the rear of the fuse. With the receiver midway it will reach both the battery and servos in the rear and also the throttle in the front. The rudder is effective and I plan to leave mine the same size as my first plane when I build more of them.

Since I placed the disk plane on RC Universe I have had several more flights with it and have learn something about it each time I fly. Here is the latest; it will do a perfect flat spin. When I say flat I mean flat as a pancake, not with its nose up, and at times it will hold its altitude without descending. It also has a move of its own that we call it a pirouette. It is a spin with its nose up high but not vertical, and of course with its nose high attitude it will maintain its altitude or ascend with more throttle. It is easy to get it to descend while doing this pirouette, and it is like a giant tail slide all the way down to the ground if you like. I have done several descending landings from about 50 feet high with engine still running. I haven’t tried the disk with a steerable tail wheel yet, but I know it will perform better being able to turn tight on the ground. It may even do a doughnut takeoff. I have had some planes that would almost leave the ground in a doughnut spin, but not quite. This could be the first. James Goss
