Does anyone have any recommendations for a good second plane? My younger brother is now a very competent pilot, flies his trainer very well, and also flies my aerobatic planes with ease. He's looking for a good aerobatic plane of wood construction that is agile enough for good sport aerobatics, hopefully durable enough to absorb the occasional rough touchdown, and in the 25 to 40 size range. Oh, and of course, it must be electric. Would the new Sig XA-41 SBach 300 fit this role well? Any suggestions?
