Getting ready to pick some servos. No crack pack for me, cant use em cant pay for em, so I was looking at the Ole stand by Fut9252s, not wanting to follow blindly I checked out several others including the 9452s.
The 9452s are faster, more torque, rated for 6V, Metal geared,and with a bit of shopping can be had new from a good vendor for $69.90 each. Basicly the same price as the 9252s.
So why isnt this the ole standby servo and what am I missing. I did notice that, at one site, it was listed as a ground servo.
All comments welcome, 200+ bucks is alot of $$ to me and I dont want to make a poor choice.....
Ah..Ive made those B4!!

go with the 9452. it will save you $$ in crash because the gears don't strip as easily. Plus they are faster and stronger.

The 9451/9452 servos were designed for RC cars. Some have said they lac centering ability but many people run these and are very happy. I had set that I put 250 flights on and they were excellent!

Get an extension for your farthest servo, the wires are short.

Good luck.

PS. expect to get a few this topic has been covered posts

IT's what I do.

I have a new Vibe 50 and a new Align 600n both equipped with Futaba 9452. Awesome servo for the money IMHO. Great choice. To go better you have to practically double your money.

You won't be disappointed. The heavy duty servo arms they come with are excellent as well. It's about time Futaba got on track in that department.

Of course, if you are building a T-Rex, go with the Align servo wheels - they are the chitz!

Fboss:

We used Futaba 9252s as recent as Las Vegas competition 2008. It was used in Justin's 9s Trex600. The only reason I took them out was because I did not want to carry two different brands of servo arms and two differnt brands of servo gears while doing the rebuild after a crash.

If we can spank a heli with those 400+ flights with them, I'm sure they will not miss a beat for you. My recommandation is go with non metal(brass + aluminum) gears as metal gears will develop slop quickly unless they are specially coated on a more expensive variety. We used them with 5.8v Align regulators and other 6v regulators.

If you crash, the plastic gears will either be good or bad and nothing in between. Aluminum output gears will typically never go but the smaller brass gears can either go or be stressed enough for future failure in a non crash situation.

We use either Karbonite geared servos or Titanium geared servos but no metal (typical) servos.

What airframe and what hard maneuvers do you intend to do that will require a servo stronger than 9252s?

You can get servos with as low as 70-80oz torque and 0.15-0.2s travel time will be sufficient to do most 3d flying except rapid aileron tictocs. Think about the maneuvers you do and see how fast you would move your stick. You will be surprised how slow they are.

This hobby is expensive enough and spending more than necessary will not make it fly better. Unless you are Alan Szabo.

Actually, I do know someone who can spank a 90 heli with a DS821s.

I will be installing in a Raven 50 E conversion (ccpm). My flight evelope is small, non 3d, loops rolls, sport. I dont expect the conversion to be a monster eventhough the components are all very good. (tango45-08 & CC85HV) A123 power. In the end she'll be a heavy weight at over 8.5lbs. Intended as a learning platform and because I thought the Heli wa a good deal. Id guess a good 600 would be in the future for these components and HOPE my skills will advance to take advantage of the potentional of equipment. I like your point about the metal geared servos and would not have thought that prior. I do want to run 6V and the 9252s are not rated for that. Speed and torque requirments are future needs, I hope.

Benny, the upside to the 9452 over the 9252 is that the 9252 is not rated to operate at 6V.

See futaba's website:
http://www.gpdealera.com/cgi-bin/wg....pgm?I=FUTM0222

The S9452 is rated with faster speed and more torque and built to run at 6V. The gear trains on mine are rock solid still after many flights.

The 9252 is getting a bit old - it's a great servo I have flown them time and time again but the world turns and advances are made. The 9452 is a great step up and it's almost the same price as it's 9252 predecessor.

My new helis fly with NOTICEABLE improvement with these servos. You should give them a shot.

Mark:

I started to write and realized that he wasn't asking if 9252s were enough.
If two servos are same priced but one has better spec simply because it was introduced later, choose the latter of course.

We currently use Hitec servos like 6975 and 5996 mostly, and I wasn't about to recommand them as that will get me pinked.

I'm not knocking Fboss or or any other novice/intermediate pilots but I just don't see putting in 8717 servos or equivalent servos in their helis to do loops and rolls. It is their money and if getting more expensive servos for a bragging rights, they should do it for that reason. But, I hope they don't pick it thinking they need them to fly better.

For this reason, I was thinking of installing what I believe to be the minimal servos to do 3d and post the results so beginners don't go out spend top shelf servos for their learning heli.

Man I'm with ya! I think we pretty much agree.

Yikes, I hope I'm not there when they are trying it


Get the 9452s, they are my first choice as the first step down from 8717s or BLS451's

People don't ever do this!! I was just using it as an example of going extreme in the other direction. But, I did see a R90 on ebay with those servos.

Yes me TOO, as posted, the crack pack is not for me! I was thinking the 9252 or the 9452 were ARE the mid priced servo that could take me a bit farther than a basic $30 digital. Are you guys saying that this is too much servo? Id say yes to that at my present skill level but Id rather get a servo I can "learn" into rather than have to buy new when its time to get a better ship. I thought or I am looking for a real good servo that is not top of the line but is very able. Looking for the best bang for the buck all things considered. No doubt Im a budget flyer, on the other hand, junk need not apply. I am open to options, Bling, ego, and flight line bragging rights are not factors to me. Good solid equipment Ill save for and pay for.

Actually, they were first designed for helicopter application!
However, Futaba released them as a "car" servo due to the popularity of the the 9252.

Go with the 9452, you won't regret it (I have the 9451's).

On the other side, I've also been using the 6965's from Hitec, and these are nice servo's as well.

NO SOUP FOR YOU!!

To add to the fire:
For my Trex 600e, I bought some brand new-in-box Hitec HS-5975's , karbonite digital servos. They were early digital introduction from Hitec, and were supplanted in their line by the HS-6975 (excellent servo as well).

I got the set on ebay for $45 each from a reputable seller, they work very well in my Trex 600, but maybe a bit low on resolution. I have not done back-to-back evaluation. I fly the heck out of that heli, they've been great. Quicker than my radio is, so no limits there. I think you can find more of them still available. They use the same gear set as the current HS-6975.

The other Fut. options listed above are great too.

Never, ever, ever, ever give up.
