RE: Pattern plane for an OS 61 FX
Two come to mind for pattern. I have had good luck with a Cermarc Javalin II with a OS 46AX so the 61 should be within the range, It is a very inexpensive ARF. The second is a Koyosho Oxalys. Both of these a are for medium to advanced flyers. For a better comfort level you can't beat the Hangar 9 Ultra Stick for a Sportsman starter.
