So I've been trolling these forums for the past week or so reading up on different posts, but I was looking for some suggestions on which copter to go with. Currently I have some basic flight experience using a friends copter who doesn't live in the area anymore, so I was looking for something that I could re-learn with and expand with after practicing. Since my budget isn't too large, mabye $600 tops, I decided to look into electric copters over gas/nitro ones.

From past posts that I've read, a copter thats 450-550 would probably suit what I'm looking for, since I want to have a copter I won't outgrow too soon. My current research shows mostly RTF copters. I'm not saying RTF is a bad thing, I'd just like to find a copter that is not assembled or only partially assembled since I'd want know how the copter is actually put together. I would be looking for some complete package to mostly assemble with already upgraded parts since I hope to have the budget for that.

I'm welcome to suggestions and any help I can find regarding this, let me know if there's anything else I should know when trying to narrow down my search for a copter.
