Steering Servo Upgrades?

[Digital Liquid]

I am thinking about upgrading the stock steering servo and wanted to get some feedback about a couple I am checking out:


Hitec HS-5645MG
-----Torque: 143/164
-----Speed: .23/.18
-----Price: $55

Tower Hobbies TS-70MG
-----Torque: 106/133
-----Speed: .24/.20
-----Price: $38

Hobbico CS-70MG (specs look just like tower's brand)
-----Torque: 106/133
-----Speed: .23/.18
-----Price: $40

Futaba S3305
-----Torque: 99/124
-----Speed: .25/.20
-----Price: $35

Hitec HS-645MG
-----Torque: 106/133
-----Speed: .24/.20
-----Price: $40


I am a little cautious about the HS-645 because I have seen some mixed reviews on it. Some people have had alignment problems. They say that they have to adjust the steering trim on their remote every time they run the truck.

Anyway, let me hear some feedback on your experiences on any of these or if you have a better one to recommend. $55 for the HS-5645 will definitely be pushing my wallet. It looks good but too pricy for me right now.

I run the HS-5645MG servo for steering duty in all of my RCs (T-Maxx, Savage, and Mugen Buggy). Great servo. Money well spent in my opinion.

Sky, have you ever had any alignment problems with them? For example, you might align them one day. Put the truck away, pull it back out and turn it on, & find that the alignment is way off. That is what some people have been saying about that servo. Reliability is important too.

i run hs 5925 and hs 5945 digital servos oh my god 5925 with 130ozin 5945 with 180 ozin crazy servos but they are kinda expensive like 85 dollars a piece but i think they are worht it!!:idea:

Great for my T. This thing will turn on a dime and give you 9 cents change. Did have to set the steering adjust a little, but no alignment problems.

i also have the hi-tech 645, and it works great. i would definately get it.

also u can check out the Cirro(soemthin like that), the Cirro M80, it has a clear case. i have heard good things about that too, and its only $28 and u get about the same amount of torque and speed as the Hi-tech 645.

Where is a good place to find the M80 servo? Links?

Thanks....:w00t:

review on servo
thats all i got, i dotn know of a web site link, maby www.cirrus.com

later

well here is what the review said(link doesn't work)

Cirrus CS-80 2BB MG Super Torque Servo
I was looking for a stronger servo, but didn't want to spend a whole lot of money. A few people suggested I try the Cirrus CS-80 metal hear servo. I picked it up at my local hobby store for $23 and checked it out, figuring for that price, it can't hurt to try before you go spending $40-$100.

Don't get me wrong, the Traxxas high torque servo works pretty good, but with the bigger heavier tires I've been trying, it's under a lot of stress, and I wanted to get something with a bit more power to help move the bigger wheels.

Installation was super easy, these servos are all the same size. You just pull the other one out and put the new one in. I used my stock Traxxas high Torque 2055 servo for the steering and brake.

The servo comes with a variety of horn, but I just used the stuff that was already on the truck, and it all fit perfectly.

The torque rating on this servo is substantially higher at 129.86oz, (measured in ounces per inch) but it is slightly slower at .25s (measured in seconds, how long it takes to turn 60 degrees) but your only talking about a few 100ths of a second and the 44% more power is worth the tiny speed difference. The stock serve is somewhere around 80oz, and .19s. The speed difference is almost undetectable when running the truck and the increased torque is a real plus.

Installing the servo is easy, as it uses the same Futaba J connector as the stock servo. I opted to use the stronger Traxxas servo to replace the servo used for the brake and throttle, for more brake power.



....

IMPRESSIONS:
The servo is definitely stronger, and works better, and hopefully the metal gears will hold up to some pounding.

LIKES AND DISLIKES:

Love the $23 price tag. The servo runs a bit rough, but not really noticeable unless you pay close attention, and definitely something I'm willing to live with for the excellent price advantage.

the cirus servo link doesn't work but the Servo city link does work.

Thanks for the info. I will definitely consider it. You really can't beat that price and amount of torque you get with it.

I also have the hitec 645mg works awesome. Never had a proublem with the allignment either. For $40 you can't beat it.

 

[StrechM]

I've had one 645mg come apart on impact and the other I've had no problem with.

 

[Willthethrill]

I'm thinking of replacing my throttle with a high speed .08 speed servo. it is sooo fast!!

I have not had any problems with alignment on any of the three servos in my rides. I have two replacements servos for those just in case moments when I tank the ride and need to do a field repair, but so far I have not had to use them. In fact, I gave one to El Pirata to replace one of his servos with.

I like the digital servos and practically swear by them.
