Finished up my PDK Ringmaster 593. I purchased just the wing kit from Pat and did the fuse/tail from "on hand" stock.
Fuse is a build up profile at 3/4" wide.  Lengthened the nose 1 1/4".
Cobra 3515/14 950kv
4S 2700 Zippy Compact lipo
Generic 40A ESC from eBay
Hubin timer
13x5.5 EP cut down to 12" APC prop
Monokote on wing and tail
Rustoleum on fuse , fin, and wing trim
.015 by 63' eye to eye lines
46 1/2 oz ready to fly with 3/4 oz tip weight.

I should have only lengthened the nose by 3/4" as I had to add 1 1/2oz tail weight to get to 16% CG.
It took 4 1 minute flights and 2 5 minute flights to get the Hubin timer values set so I could use the throttle compensation mode to give me 5.2 second lap times through out the flight.  Was very easy to do.  The 40A eBay ESC at $13 delivered was a gamble but looks like it will work out fine with this setup.  I think a very good setup for sport flying!

John,
Pat King has a kit that is 125% size. Thus the 593 wing area.
Flaps on a Ringmaster?  Sacrilege I say!

Very nice!  However I thought the big ringmaster was a 576 that could be built with or without flaps..  Is there a bigger one at 593?  My 576 has flaps.

I have, and have flown at stunt contests, a ringmaster 1000

Ringmaster envy?

Ha!

The 1000 was built from Pat Johnston plans by Larry Marx.
Pat King kits an 850 and the 2X, which is a whopping 1536 squares! Pics are of John Stiles

Dave, sorry to wander on your thread. Beautiful model. A lot of us are passionate about big ringmasters!!

The Lafayette Esquadrille has an OS-90 four stroke powered 2X sized Ringmaster (we call it the RingMonster). With that much wing area it floats on landing and it flies at 1/3 power with that .90 sized four stroke. We have 2.4 Ghz throttle control on the beast which makes it very managable. I do have to use my trailer to get it to the flying field however....84" one piece airplane, what were they thinking?

Thank you Bob!  Very kind of you.
