This may have a simple answer but my brain doesn't work quite as well as it once did so I thought I'd ask.
I have a new 2m sailplane (powered). To balance properly a considerable amount of weight will have to be added to the nose. Of course that weight will be right up against the motor and probably upwards of 6 oz. The plane has a good size aluminum spinner (50mm) with alot of empty space in the spinner. I'm thinking about melting a certain amount of lead and weighting the spinner. Of course it has to be done in such a manner as to be perfectly even and then a hole drilled back thru the center for the attaching screw. But I'm thinking the further you can place weight---the less you need. Is this worth pursuing or am I way off base?
