If you wanted an improved servo for a .40 sized profile what would you use?

I have been using Futaba 3010 servos with pretty good results, although they seem to drain batteries in a hurry (I typically get only three flights from a 600 mAh NiCd). I have recently upgraded to a 750 mAH 5 cell NiMH because I thought the NiCd was going bad, but it cycles at/above rated capacity. Futaba recommends against NiMH batteries for this servo, and I have heard complaints about centering (although I have not had that problem).

What are the other alternatives? It needs to handle 6 volts, stand up to the abuse of a profile plane, cost less than $40, and be superior to Futaba 148 servos. Hitec and Futaba have new "standard digitals" that may fit the bill.

Comments anyone?

I have played with the futaba cheapy digitals but was not impressed. In the under $40 range I like the 9001 Futabas. They are fairly fast and plenty strong. They have a coreless motor which accelerates faster (supposedly) than a conventional motored servo. I have digital 9252s in my Burrito and 9001s in my EF Edge. I can't really tell any difference in the in-flight performance. I haven't found and Hitec servos that I really like. Their specs might say one thing but I have compared them side by side and the faster rated Hitec is slower than the Futaba. I think I was comparing the HS-645 to the 9202 Futaba. The Futaba was faster and felt much stronger even though it wasn't rated as high.
I'm sure someone may claim the opposite though, it 's kind of like the Ford-Chevy debate.

How about some Jr 811 digitals servos? Got 2 on ailerons of my sledge and they seem to work real good.
Specifications:

Torque: 54.0 @ 4.8v or 66.0 oz/in @ 6.0v

Speed: .18 sec @ 4.8v or .15 sec @ 6.0v

Size: .0.75" x 1.49" x 1.52"

Weight: 1.44 oz

I will second the JR 811 digitals. I have 4 on my EF profile Edge 540T and am really happy with the performance. Good centering and plenty of muscle. I am getting ready to buy a few more for another EF Edge I bought as a spare.

I have several dozen cirrus CS65bb servos in my planes. 48.00 for a coreless servo with speed of .13 and torque of 121 oz. Too bad they just quit making them. The centering on these is superb

I have used the lowly hitec 425, double BB standard on many profiles and they work great, especially at 6 volts. They center very well and for about 15 bucks a piece you just cant find a better "standard" servo IMO

I'm using Hitec 85 metal gears. It cuts the weigh dramatically and seems to do the job. Until I have a failure I will keep using them. I know the guys at OMP have had them on a 540 for a long time with no trouble.

I'm with smallfly here. I've been using the hitec 425's. Cheap, and work well. I have no complaints. I also have a set of Futaba S3004's. When I'm flying I can't tell the diff.

I've been using the Tower Hobbies TS-69 servos with a 700nimh 5-cell pack. They are 1 for $14.99 or three for $41.97.

All I can say is when Gary Seeloff flew one of my planes he said, "I like the servos."

DOH! I just KNEW that was gonna come back and bite me....[] In my defense, I said that after checking the controls BEFORE I'd flown it.

In all seriousness, a plane with "standard" servos usually feels sluggish to me right off the bat. Running 6v and making sure the hinges and linkages are free, as Tim does, helps a bunch as well.
