IMHO
The secret to making the Espada RL fly sweetly is the CG. I've found the recommended of 102mm a long way out for me. 95mm from the LE is it.

Before it was draggy and twitchy. Now with more lead in the nose, it's got that "have a power-nap-wake-up-and-scratch-your-tackle" hands-off stability.

Warming to this glider. I was cinsidering selling it on, but will keep it for a while longer. Distance mode (clean wing) is very impressive with very low height-loss for distance travelled.

Yet to try it with ballast. Also need to increase roll-rate agility.
