The field I'm flying on has some pretty stout weed stubs even though its cut fairly low. A new set of .015's was kinked into uselessness a couple of days ago in just two flights on my Ringmaster. The .018's seem to handle the weed stub issue much better than the thinner lines.

The CG isn't too bad now. Its snappy, but not unstable and there's no tendency to "bounce" out of a sharp turn - it'll stop pretty quick. I think some of this is due to the scale aerodynamic balancers on the elevators. Years ago I build a VooDoo with the pivots on the stabilator inset maybe 1/2" rather than on its LE and the aerodynamic balancing that provided made it fly like it had power steering.

Something with a closer line spacing than my old HotRock would make using a light touch not so necessary. I really need to buy/make a real adjustable spacing stunt handle once I get beyond the rudimentary trimming.

The wing shape is definitely a tough one for the leadouts with any airfoil with a 20-25%ish high point. It does however have some swept back wing stabilization effects from the high point (and section CP) sweeping back towards the tips. It seems real solid in a gusty breeze that bats a Ringmaster around rather badly.

I might try a bent I-beam on another one to free up some space at the tip. The front leadout probably wants to be about 1/2" forward, but there just wasn't any way to put it there without compromising the straight I-beam's strength.
