RE: Choice for 1st plane
If that parkzone cub flies anything like their decathalon I wouldn't recommend it. The BEST first plane would be a bigger one, I'd recommend at least a .40 size trainer or up, mainly because they are so much easier to fly when they are big. But if you really need something compact, durable, and easy to fly, I'd say go with a Zagi!
Keep the throws low, and the thing will fly great. Plus you can run it straight into the ground and all it will do is bounce.
