I've got a 1963 NIB RISE ST double ringed .71 engine (stamped control line stunt by factory on box lid). Speed vent & NVA rear. What kit would this anchor be suited for as the manual shows a 13" to 14" 5-6 pitch prop choice? Any info greatly listened to. William

Unless you are going to use it in FAI competition it isn't legal. Max displacement is .67 for a 2 stroke through the end of the current rules cycle.

As far as the plane for it how about Windy's SWEEPER would be period correct as it was designed in the 60s. Real big 88" wingspan.

Actually the limit for FAI at the moment is .61. Both should change with the new rules cycle in 2005. But you could certainly build a plane and fly it for fun even now. However, this isn't going to be a barn burner compared to current engines of lower displacement, so any plane desiged for the current .61 to .65 engines should be just fine. Try a Brodak Strega, for instance. There is a lot of plane for the money.
