RE: What size StiK?
I absolutely agree that the Midwest Sweet Stik was the best of the Stiks I have flown. Too bad it is no longer in production. Like you, I acquired a set plans, so one of these days...
I'm just finishing up a GP Big Stik 60 with a ST 75 for power. Maybe not the best job of kit engineering, but not the worst either. Wood was somewhere between balsa and oak (honestly, some of the balsa wood was 18 lbs/cu. ft.). Yet it is going to come in at about 7 1/2 lbs when finished, giving a wing loading of about 19 oz/sq. ft. This will be my 4th or 5th stik since 1970, and I built it because I wanted a no bother, easy to maintain, cowl-less model for a change.
