I vote for blade 450x (even if you asked 450) .... If you got the money, thats the best investment you can make. It's an awesome heli! Inherently stable with the Beast system, and flies amazing! As nimble as you want, and as agile as you want, all you need is to change some tx settings and off you go!!

flies almost straight out of the box. This is my opinion from experience. Helped 3 new 450X owners till date.
There are somethings to note/ tighten/ oil and make sure to do before flying... But thats just Maintanence... Some known minor issues, but again, nothing in this hobby is perfect.
If you want to build and do custom setup, then chaos or tarot is what I would go for. Never flown chaos but heard good stuff about it. Tarot.. I fly it, it's awesome. This will Br cheaper to start with and flybarred..
450x will be flybarless, and just the gyro which you can reuse in a future bird is 250 by itself.
