Tom Dixon has a set of plans for the Tutor (44" wingspan) with notes on suggested improvements. They are $10.00 plus $3.00 shipping. http:tomdixon.tripod.com. (There's no "@" in his website address). I just ordered a set of Baby Barnstormer plans from Tom and the turn around time was impressive.
So, if James can't find his plans, you could order a set from Tom.
