The Trim Sabre has plenty of structure on the TE, but is balsa. So given that, should I use CA hinges, or continue using Robart. This is a very large kit, and the TE has a large block of balsa for the hinges to go into. Also, if I go the Robart hinge point route, do I need to use the hardwood block method to notch the control surfaces (these do not have plenty of structure, just foam with balsa skins and fibreglass covering).
