Seems kind of dead here.........so..............a question:

        Did anyone here ever build a Riley Wooten PIRATE (June, 1955 Flying Models) and not have trouble with the inside wing bucking where the main spar (1/8 x 7/8 x 36) was relieved of some wood to allow movement of the belcrank?  I did in 1955 and so did a flying buddy.  We both used K&B .35 greenheads for power and both planes had the inside wing fold at the belcrank, after a few flights where tight maneuvers were performed. I know Riley used the Fox .35 stunt (less powerful) in his versions, but It seems that there was a design flaw that was overlooked and was included in the published article/plans.  I am betting that someone out there has had the same experience..........TDurrill          

Did Al invent it for Riley in 1955?

You have to get to know Howard.   By the way don't pull his finger.
