I am very sorry for your loss. I knew your grandfather while I lived in Victoria during the early 1980's (in my 20's then). I met Leon through the Victoria RC club. I was new to RC modeling and Leon taught me how to fly. Several times, I would visit his home to see his workshop or just a visit. He shared his love of flying, full size or RC models. I recently reconnected with the RC club and learned of Leon passing. Leon will be missed. Please accept my condolences.
