RE: ARF's of the old Classics
The Kirkland A-6 Intruder was originally designed in 1969 with retracts. The same is true for Jim Martin's Banshee. I kit both and have the original plans. As several of the other folks have already said, you put them in and then if you want to fly SPA, just cover over the retract wells and don't hit the switch. It is certainly an area which should be explored a bit more. It seems the VRCS folks don't have a problem with retracts if they are shown on the plans. (Such as the A6 and the Banshee) Perhaps this season can bring about further discussion on modifying some of these positions.
