RE: First 3D Plane
Small planes aren't going to do both well. Sorry. If you have a .46-sized 2-stroke, there are a lot of cheap planes that will do a GREAT job flying pattern. There are a couple of choices I can think of off the top of my head: [link=http://ecsvr.com/abm/shopexd.asp?id=1335]Example1[/link], [link=http://www.kyoshoamerica.com/airplanes/index.php?part_num=11852]Example2[/link].
Learning with one of those and a profile plane, like a Mojo or OMP Edge, would be the best way to do it. If you want a plane that can do both, here's one option: [link=http://www.nitroplanes.com/yak523d5056n.html]Example3[/link]. That plane is a cheap little plane, but I've seen a lot of videos of it flying beautifully and have heard nothing but good reviews of it. It's got shoddy hardware, but for a 40-sized plane it's not that big of a deal. I can't find the video, but it was on RCU a minute ago. I have a plane with about the same wingloading as the Nitroplanes Yak54 I just linked to and I like it better than the plane I just spent $900 on (hopefully that'll change, but I won't get into that). I absolutely love the way the cheaper plane flies.
If you don't mind learning up high and spending a lot of time on the sim, that Yak might be a good option. Set up triple-rates on it (2 for different pattern rates and 1 for 3D) and have at it. If you learn to work on one maneuver at a time, that might be the way to go. Nitroplanes also has an Edge and an Extra in that size if you like those more (my favorite aerobatic plane is the Edge 540T) but I think they're out of stock.
