Wanna talk about saving some money---These servos are made by Hitec but are not programmable...Which is not an issue with me...After discounts I paid about $35 each for the CS 150 metal gear digital servos with 162 inch ounces of torque at 4.8 volts and just under 200 inch ounces at 6.0 volts..The are installed in my 50cc Chip Hyde Vision...They center and perform perfectly!!!

Have over 40 flights on my Boomerang Intro with HS-5985MG on elev and HS-5925MG on aeilrons with no issures. The HS-59**MG/TG series servos are a very good value.

Note to all, put your servos where your mouth is, I'll trade anyone a hitec 5645 for a JR 8411 straight up and I'll pay shipping both ways. I'll even give you an extra 20 bucks per servo for an 8611 on up.

I have two 5645's I'll trade.

i use hitec hs-645mg for most of my jets never had a problem.

I'll trade you my 8611A's for two Hitec 5955TG's.

Marty

Whoa, wait a minute, a 5645 isn't as good as an 8411 or 8611?

Come on you hitec guys that use 5645's.

I won't buy a hitec digital servo because of the 5645. And they were the only ones I ever bought.

It's the 59xx series that is the equivalent of an 8411--Not the 56xx series..

Kevin

Actually a 5645 is twice as good as an 8411 cause I can buy two of them for less than an 8411 and have enough change to get some Chinese takout as well as getting two aluminum servo arms in the box that Horizon charges like $9.00 a piece for and they don't even fit on the splines[>:].

Marty

Looking at the specs the HS-5985MG would be closest equivalent of an 8411. Here is good link with lots of specs.

Sean, if I had Some JR servos I would trade you in a second!!!!!!!! (for even cash value of course)

I don't have any JR servos to trade... never bought any except some standards that came with my 783. But hey, they are like new as I never used them.
I think JR servos are good but I think the Hitecs are a better value.

I have 9 new 8411's that I'd trade for 9 new 5945's or whatever the replacement for the 5945's are!!!!!

ok now common
i have heard many comments from prior threads.
Hitec HS5955 is better than jr 8611a. Hitec uses titanium gears.
I am also convinced JR8711 is same servo as Hitec 5955 as both same specs and dimensions.

The whole titanium gear thing is curious. What I would like to know (if someone could take one apart and tell us) is if there are any nylon gears within the case? If they all are titanium it would be pretty strong, but if only some of them are titanium it might be just as weak as the weakest link.

For what it's worth, I own and still am a fan of Hitec servos, can't beat their price and I've not had any issues. I also use some high end JR's and am happy with them as well.

All Titanium. I know, bad pic, but my poor camera is old. This is a 5995, basically the robotic version of the 5955.

Any experience of using Hitec Servos on a Kingcat?

Here are the sepcs. http://www.hitecrcd.com/product_file...2/HS5985MG.pdf And is clear that these servo have one metal-karbonite and 3 metal gears. The one metal-karbonite is the one where you install the arm and is the one that fail acording to others users. I can not get the thread with the photo of the broken gear. I think someone post a remedy for this problem. But honestly I can not find it.

The first gear is nylon--The rest are either metal alloy or titanium depending on the servo. The nylon gear is the first gear that is driven by the motor--This gear is so far down the gear train that if the servo did take a hit it will never strip...By the time the force gets to the nylon gear it is reduced by the gear reduction in the gear train...take a look at the gear train in this pic---Same as the Hitec titanium gear train as these servos are both made by the same company...

Kevin

Funny how some manufacturer's won't spend 2 cents in effort to hide the fact that a product is just OEM'd from another and has a different sticker...

Anyway,
I should clarify my post earlier, as I didn't mean to make anyone 2nd guess a recent purchase... I'm still a Hitec user and I do think the 5625 or 5645 are OK servos, but just not what I'd use for any high end model. I'd still use them in a Diamond Dust or something that required a little above average performance. I had them on the elevons in my Stingray, and the centering effect on elevator trim was much less obvious. The effect on roll trim was however very obvious and that's why I changed them out. Otherwise they worked fine. You could probably get away with one of these on an elevator or flap quite easily and not notice any problem centering, even if your servo performed as mine did. That being said, the 59XX series are only marginally more expensive and far superior products in my opinion.

Kelly

yeah, but that was a very twitchy airframe to begin with

I have used hitec servos for the last five years in all my planes, jets and helis. the only servo that is not hitec is my futaba 9254 on the tail rotors of both my raptors, nothing that I have found can beat the speed of a 9254. After losing a plane to an overprice JR servo I switched to hitecs and have not looked back. The gear train does not develop slop as fast as a JR servo, the programmability of the servo is an added bonus (no matchboxes needed), and the cost is very attractive. I have used the 56XX and 59XX series in all my jets, and have not had a problem. The one thing I do, is break in. I put all my servos, not just hitecs, through a break in period where I have them cycle back and forth for 30 minutes to see if it is going to break or develop bad centering habits. Highest priced does not all ways mean best quality.


Patrick

I also cycle/burn in/break in my servos.

Pat,
I exercised all my servos for my F-15 for a total of an hour and then while setting up the elevators had an 8611A start to get creepy around center. I guess if I didn't do that it might get creepy while flying[X(]. I've had two Hitec servos fail. One was a micro HS-55 for a foamy and the other was a HS 225MG. I think the 225's have an issue with unregulated 5 cell packs. Unfortunately we'll never know the failure rates of servo manufacturers but I would think that Hitec sells a heck of a lot more than JR or Futaba, so hearing about a failure here or there from any of the manufacturers really is meaningless unless you know how many didn't fail. I just don't understand why everything JR makes costs about 20% or more than a comparable item from Futaba or Hitec. I guess it's to pay for all those red shirts at the events. Like you said, I don't think the increased price reflects increased quality or reliability.

i myself use the JR plastic arms and have never had a problem with them, they'll hold up and have less wear then the metal arms (they actually wear the clevis not the other way around). the BVM guys/gals use them too and have well proven they are up to snuff for the application.

kc

I agree with KC, I have been using the heavy duty plastic arm that is supplied with the 8711 servo for years on 8411's and 8611's (even though those two servos do not come with it).

The fit of that particular control arm and strength is superior to any other arm I have used. And I believe it is the same used by BV and his team, but not for sure.

I buy them from Horizon in a package of two for about 3 bucks, and I buy 10 packs at a time. Then again I've built 5 jets already this year using only JR servos and every one of them has been an incredible success.
