I have flown quite a few electric aerobatic airplanes. But 3d hobby seems to have the best design out there. You cant go wrong with any of there airframes. For me the Extra-SR is my favorite. Great cross between precision and 3d. Which is the style of flying I enjoy. Here is a link to videos from the Zephyr electric flying. I'm doing a noontime demo with my SR.
