Well guys, my 600 pictured above met an untimely death two weeks ago.[

] It survived my poor flying skills for right at one year.

It went down so hard that the only things that survived were the electronics (luckily) and a few of the metal head parts. It ended up being cheaper to just buy and build an entire new kit. So I ordered one of the new "improved" 600ESP kits along with some replacement servo gears and a couple of servo cases. It arrived last Wednesday and I was able to get it built and fly it for the first time on Saturday. I am still running the same 8S setup with the Scorpion HK-4025 890kv and CC HV85. It flew great, and hopefully it will live for quite a while.
I also just added the 600N. I picked it up used and it is fully loaded with an OS 50 Hyper, 8717s, Solid G, ect. While the N is by no means underpowered, the ESP on 8S definitely has quite a bit more power. With the N I have to watch my collective and cyclic to make sure I don't give to much of both at the same time. With the 8S ESP, collective management is purely optional!
Here is a pic of it with my other helis (T-Rex 700N, T-Rex 600N, T-Rex 600ESP, and T-Rex 450 SE V2).
