The plane is balanced with the tank empty , so putting the tank on the CG is fine, the plane won't be adversely affected when fuel weight is added ...It's on the CG line, Iv'e filled the tank on mine full up ,took off, turned and landed still full up... now adding the 14oz's foreword of the CG when the tank is full , and the plane still handled great ,Correct me if i'm wrong, but if the plane is hovering the tail act's as a pendulum , Now if all gear is centered in the middle of that pendulum, wouldn't the plane fly better?... I don't see any problem's mounting the tank on the line, I only see Positive's in doing that.....A very good contribution to the Ministry Of Aviation.....

. As far as the tank and CG. On 40 sized craft the center of the tank and the CG are within 6 inches of each other. On this long fuse the center of the tank is now 10+ inches of seperation. As the fuel draws down, I've experienced a good deal of chenge in the CG in flight. On the last three my 5 cell battery was always in the aft. of the compartment. So if it has to go forward its no big deal. Now the only change is the weight of the plane as it burns up fuel. With the tank on the CG you still have the option of makeing the CG as mild or wild as you want. Joe
