How about a top/plan view. You went to a negative angle on the tips? Thermal use? Slope?

You can use small diameter tubing and small wire wound guitar strings as the "wire". The wire wound guitar strings will flex around the tightest bends you can make in the tubing. As guitar strings come in many sizes you can find one that is a dead on fit for the inside of the tubing. Solder the ends to stiffen.

I've used this is a very small scale like sloper that a friend wanted built where the wings were just not thick enough for even the thinest servos. Put the servo in the fuse between the plug in wings. Left the whole thing assembled as the linkage was a PITA to connect. Could do the same but put the servo closer to the root of the wing where it will fit.
