I am building Bambina from the 2019 RCME Special Issue plan. Like many people, I'm building it without u/c and am concerned about the vulnerability of the aileron servos. So I'm using the small, thin, metal-geared wing servos from 4-Max and installing them so that just the servo arms protrude. I'm using a short piece of carbon rod to (hopefully) protect the servo arms. As in the attached photo.
I'm also going to use the Hobby Eagle A3 Pro flight stabiliser - it's small and light (9 gms plus cables) and there's plenty of room for it above the wing.
