You could get a 4 star 40 made by sig. It is GREAT with a 46. I have one and I love it. You can get it in kit or arf form. I wouldn't go an extra or a giles as a second plane because they snap very easy and are highly aerobatic. Not a good choice if it is your second airplane. You could also get a great planes cessna or a super sportster. Also the u can do 3d arf 46 would be great.
Hope this helps
