RE: Battery & balance
i'm a believer of doing everything needed to keep other problems arising, but i am with 1932 on this one.
however, i realize that the bigger planes are not nearly as affected by added weight as the samller models.
so i have a question to add into this, what if the area that the battery is moved to which is up by the ignition module, is shielded with some sheet lead?
helps of course with the balance, but also preserves the lightness of the model.
