Larry, Oh, my bad! I didn't understand that you "got this ARF for a give away prize", I thought that YOU had won this plane at an event and wanted to assemble it for yourself. You said it right, I read it wrong! It all makes more sense now. Yes, slot the holes in the aluminum. Look to verify that the wooden beams are predrilled and match that dimension for spacing. The winner at your club's event will recieve a nice flying plane. Regards, 52Larry52
