I am getting an older unflown heli ready for flight, I've been around the hobby for awhile, but still an extreme novice. What servos should I use? High torque, or High speed. I am aware of the need for ball bearing and metal gears, so I am trying to get the total package in one. Any suggestions??

s9452 servos are the best bang for the buck IMO.

The new align servos are said to be pretty nice also.

speed and tq are not very important if youre a noob. With high speed servos you'll have to run a lot of expo and since your not a crazy 3d pro you'll prob never load the heli up enough to need a high torque servo.

i would go with a decent digital servo thats cheap.

Those seem pricy for a novice, unless they are flying something LARGE. That there is a ton of torque. If you are talking a .50 or .30 size, I don't think you need that much servo, especially if you plan on crashing (I would plan on crashing). Hitec makes several that would fit the bill, and there are a couple of Futabas that would be more than adequate for a novice for far less money. Unless you are at "that" level of expertise, you don't need the fastest/toughest/highest-torque servos to move your swash. My rule of thumb for sport is find one that has a speed of about .20 sec. or so. Lots in that range with 60oz/in or more torque. The 120 + change of the 9452 is great, but you pay for it and it is a bit of overkill for sport flying on anything but the largest helis.

My R30 flies great on standard, cheapy futaba S148 servos from an older system. They are equiv. of the S3003 servos. Never a problem with them.

Still, nylon gears. The S3010 is a higher torque servo of otherwise similar specs.

Getting good servos the first time is usually a smarter choice than cheapo servos imo. I run 9452 servos and they're awesome servos, just like my 9451's were. Good servos center way better are smoother and make heli flying just more enjoyable. A heli with say 148's on it will fly yes, but the experience will just be getting by. Flying 148's make the heli feel like trying to balance a ball bearing being on a ball, versus a ball bearing being balanced on flat glass(good centering servos).

It's a pain to make a adjustment and then center the cyclic only to have the servo not come back to the same center and then you have to make a extra adjustment to compensate for that lack of precision.

At $75 a piece for 9452s, that is pretty darn cheap for what you get imo because those servos are simply excellent performing and have only been dead nuts reliable for me. Also, they simply hold up great to crashing, can't think of a better servo to crash, lol. Between my 9451's and 9452's I have a combined 6 crashes, some hard some not and the servos still worked and are working perfectly.

From my experience, I know some of the crashes which were hard would've blown cheapo servos.

When I was a newb, I got Futaba $80 a piece 9404's(now discontinued) and my other newb buddies with cheap servos thought I went overkill. Well, 3 sets of their cheap servos to my one set of good servos changed their mind, good servos give a lot more than just performance, they give much much better reliability and durability.

I was told for a 50 size, S9252 for cyclic and S3151 for throttle.

Throttle servo??
Can you use a standard servo for the throttle or should I get a better one for that as well.
Thanks

i dont seem to notice a difference but if you ever want to run a gov. then you might want a faster then stock servo. the servo i reccommened earlier seems to be fast enough for any use though.

If you're not doing anything fancy with the machine futaba 9001's are rock solid standard servos. They're not the latest but they are a good sevro. Don't need anything special for the throttle servo if your not running a gov. Don't need a high torque servo for the throttle either.

Damn that ground is hard! When's the right time to get out of this money sucking hobby?

buy the best servo you can affort !
for sure you will be able to use them time after time.

FUTABA 9252 are great, nylon gears are available at any major e-store such as MTA or Ron's for 7-9 dollars.

Later on you will make up your mind on FAI or 3D and then, torque or speed will matter !

Best bang for your buck is the Align servos IMO. Check it out, before you decide. 3-pack for $179

The Aligns look good, but i went to my LHS and they said to stick with JR or Futaba.

Not sure on those servos. They are probably ok, but I dunno man. Aligns track record with electronics is spotty and with Futaba, JR, Airtronics, even Hitec, there is lots of years of support, info and experience behind them.

Do a search and some reading on the Align servos of people who has already tried them and come up with your own conclusion. The people at the LHS are entitled to their opinion and often based on what they want to sell you. Allot of us currently own these servos and happy with them. Just a thought.

What Im finding lately, is when I have a bad flying day and things dont seem to be happening the way I want, I blame it on my cheap and nasty .20 ms Hitec servos, but when everything goes sweet and I nail some really good manouvers, I start telling myself my cheap and slow servos work just fine.
I guess the only way to know for sure is to fork out on some better servos.
