Baby Ringmaster build

Thanks.

Were it I, I think I'd just take an X-Acto knife and cut away the hinges and just work around them. No need to cut another elev/stab set. Those look perfectly usable with cloth or thread hinges.

Any thoughts on this?

Canso, Ringmasters are seriously over-controlled.  It's true that the original design has a larger elevator than stab, but it really should be the other way around.  With the elevator smaller than the stab you're still going to have WAY more elevator than you need.  With the elevator larger than the stab as you've built it I'd recommend that you put the pushrod on the inner hole of your bellcrank.  You'll still have have more than enough elevator throw.  It's very easy to stall out the plane with the larger elevator.  On my Beginner Ringmaster I have the elevator larger than the stab and it stalls out if I give it up elevator too aggressively, and the elevator is smaller than the one you have.

I'm looking at the .pdf of the plans you're building from (I downloaded them, too), and the elevator has a very different shape than the Sterling Baby Ringmaster.  The wing has also been redesigned.  The ribs are much thinner that the original Baby Ringmaster.  If you look at the bottom of this page, you'll see several plans in .pdf format to download.  The "half a ring built up" is about as close to the original Sterling Baby Ringmaster as you'll find.

I recently built a full size Ringmaster S-1 kit, and had to make up a new elevator horn.  The original horn had the hole about 1/2" from the hinge line.  I've seen a couple of guys flying the plane with this position and they bounce all over the sky.  The horn I made has the pushrod hole 7/8" down from the elevator hinge line, and I should have gone out to 1".  Ringmasters as designed are over-elevatored.  And I LIKE lots of elevator area on my designs.
