I'm flying the TP Pro Lite V2 910 maH. And I'm using JST connectors. Congrats, you're gonna love it!

As far as upgrades go... well it's already blinged out. You probably won't need any. I did upgrade to CF mains not for any other reason other than I like CF and how they cut the wind.

I'm running the rounded ones. They do fine. I had a little tail wag but when I moved the control guide closer to the servo bending the tail servo rod slightly... all wag problems went away with the ds420 and I was able to set the gain in my Dx7 to something like 67%.

There is a lot of talk about how bad the tail is, but I haven't had any. I just tuned it and tried different things like above. I also set my Travel Adjust on the tail to like 140%. My piros are as fast as they are on my 450.

Make sure you go to Ready Heli and get the Trueblood swash plate leveler. It's invaluable and you'll get your swash perfectly leveled.

The CF blades improve collective control giving it a crisper feel & yep JST connectors same as on the ESC. Tail blades iv'e cut down to 34mm but now i have it totally sorted im sure the stock length will be fine.
