RE: CG location question
Every plan I have built, the "suggested" CG already gave a slightly-to-very nose-heavy condition. Even full-sized craft have a "range" within which the CG must fall. Otherwise, they could never allow for the fat guy to sit in the back seat, or the skinny guy to sit up front.
Setting it there should be fine, but you should probably expect to need to move it aft slightly (as your skills and experience with that model progress), by removing weight from the nose or positioning the battery farther aft.
