RE: FAI Manuvers list RC1/F3A from 1960->
Interesting that the drawing of the Manuvers from 1960 WC does not show 45 deg. straight lines between the two loops of the Cuban Eight. If flown as shown, the rolls would have to be integrated into the curvature of the loops. That would have been very difficult with the models, radio equipment and skills of the pilots from that period including this author.
Drawings for the later WC's do show the 45 deg. lines.
