Default New Servos

Hey friends, so I'm setting up my Agile 7.2 and I can't decide what servos to get. So far I have my Scorpion 4525-520, my CC Phoenix Edge 160HV, and my Western Robotics Hercules Super BEC Pro. I will be flying with my DX9 and using the AR7200BX.
Any suggestions? I don't mind spending some $, but I don't want to get stupid about it. I was looking at the BK servos.
Thanks friends!

The BK's are catching on and becoming pretty popular.
I know a lot of guy's around here running them with good results.

As mentioned before if you want to run a BEC Futaba BLS' are a good choice.
What is your budget for full set?

Heli Direct has the BK BLS 8002HV cyclic and BLS 8005 tail servos in a set for $555. I was thinking about those. What's your opinion???

I have no first hand experience with them but I don't think you'll find a similarly spec'd BLS servo combo for that price.
Come's out under $140 per servo

Which Futaba servo do you use or recommend. I don't mean to be a pest, but there are so many servos out there, with so many good numbers, I'd like to go with some personal experience and recommendations. This is my first 700 size heli and I don't want to dump a bunch of money and make a mistake. Thanks for the information. I really appreciate it!
P.S. What do you think about the rest of my set up? I am also going to be using an Opti Guard.

I use the BLS451 on cyclic and BLS256 on tail all at 7V.

Both have been discontinued or remodeled.
For a big 700 the 451's are about as low toque as you want to go, hitting ~185oz-in @7V
For the tail the 256 will do a 700 no problem.

The 451 lives on as the BLS471Sv and the 256 as BLS276Sv.
For a stronger Cyclic I'd look at BLS175Sv or the BLS275Sv.
For an FBL 700 Cyclic servo I'd look for something ~200oz-in minimum at the voltage you plan to run and not more than a .15 transit speed.

I use the savox 2283/2284 hv bls in mine.
Very strong and fast.
Great holding power.

For any servo
Aluminum servo horn are recommended if you are doing hard stops and manouvres.

I have heard good things about there servos...
I was doing the BK thing.... but have had two tail servo's go bad during flight...
Seem if ya get 20 flights in without problems there good to go... BUT BK has always replaced anything that was bad... So they do have good customer support ...

But my next build will most likely be with the R2 and R2T experts I think...
