The kit is a kit of the Aero-Flyte INVADER, going back some 60-70 years, 50" span for 1.5 - 3.5cc motors and shown on the plan for single channel.  There are two pictures of a full house conversion, and it can be seen flying on YOUTUBE. It would appear to be straightforward to build, and quite sturdy, with virtually all parts precut.  There were no accessories in the kit, not unusual for that era, but it should build into a model that is unlikely to be seen on flying fields here, or as a kit to add to a vintage collection.
