no. not at least from my experiance. here's what i recomend.this will put a bit of stress on your plane, but screw in an eyehook in the ceiling. run a piece of strong string through it. tie one end to the front of the plane, just tie it around the fuselage because your engine is ofset. now tie the other end of it to itself, but with a big enough loop that you can put your rudder through.it is very sensitice, but if you are flying a trainer, it is not necessary. while you are at it, you may as well crosshair your cg and hang a plumbob from the eyehook. obviously, if the plane falls to the right, put some weight on to see how much is needed. if the plane is level, (nose to tail) the plumbob will point right to the cg. i have a happy face sticker right on that spot
