I would like to chime in a well here. I built the original Eagle in 1984. I was 14. I was so excited to get it for X-mas, and was so nervous about sucessfully building it. Even after getting it finished, I was just excited to watch it fly and exhilirated that the build was sucessful.
That was the thing back then, Goldberg kits were about the best thing going. They had new joinery techniques that made the planes build very straight and quick. Also step by step instructions that got you flying by completing each step. Very revolutionary for the time. Super glue was fairly new along with Monokote. All very new things for me (and my dad) at the time. we were used to dope and silkspan and typical wood glue and ambroid.
I am a sentimental sap about my RC experiences and maybe one day I will build another. This airplane taught me how to fly that summer, and I will always have a soft spot for it.
