Savox servos

[Hugh Mason]

Is anyone running Savox SH-0263MG super torque servos in their 300x? How do they perform? Fit the frame? Amain hobbies got them. Pricey but look like they could be good??

[Familyman67]

I have been running those on my 300X. They worked pretty well on the cyclic. Very precise and robust. They do fit into the frame, however for the front-servo you need to make a few adjustments by cutting out some plastik from the frame - but this basically applies for most of the third party servos on the 300X.

The problem with the Savöx servos is the frequency - in conjunction with the BeastX they should only be used with a maximum of 100Hz. so for the 300X this means 65Hz on the cyclic and 50Hz on the tail (Savöx 0264MG) unless you use your computer to set up your BeastX, which I haven't.

For the cyclic this frequency is sufficient, however for the tail it is crap, and even 100Hz would not work on the tail imho.

My recommenation is to not use the Savöx servos on a Heli that runs the BeastX.

check out Chris Reibert's thread about the 300CFX - he has been using a set of hitech servos with metal gear and was very satisfied with those.

[raisinjack]

the ar7200bx manual states to use the highest freq (if known for a particular servo) and to use only the lower if is not known or it is is an analog servo.

why would savox servos be any different?

I am running mine at the stated savox settings and it works

[Familyman67]

there were reported cases over here, where Savöx servos got fried on a BeastX using higher frequencies.
I also tried the higher frequencies and it did work (the flying, not the frying).
However when I heard about those "toasted" servos, I approached Savöx directly and asked them. Their answer was to not exceed 100Hz on a BeastX system. The didn't tell why though.

Thats strange because i asked for 642 (tail) and got a different response

Good afternoon,

Could you provide me with some additional information regarding your Savox SH-0264-MG servo? In particular im after the pulse length so I can select it in my AR7200BX (beast X) FBL unit. I have it set at 1520? (I have the choice 1520 μs, 760 μs and 960 μs)

Im also after the tail servo frequency? I have it set at 270Hz (I have the choices 50, 165, 270, 333 and 560Hz)

Many Thanks

Daniel

RESPONSE FROM SAVOX

1520 μs is the correct setting 270 is also the correct setting for this servo as well.

I have mine running at 270 with no issues for the past year or so...

I can only tell you, what we have been told by Savöx in Germany about the use of these servos with a BeastX

Quote: "Wir bitten Sie die Servos nur mit max. 100hz zu betrieben, andernfalls werden diese extrem schnell verschleißen! Wir geben 250hz nicht frei!"

in english: "we ask you to operate these servos with a max frequency of 100Hz, else they will wear out extremely fast! We do not approve 250Hz,"

But again, I also operated them at higher frequencies without an issue for a while. It's just that I don't like taking that risk with the manufacturer's recommendation in the back of my mind.
They are great for cyclic, and I still fly them in my HK450 today - I just wouldn't buy them again, and I would not use the tail servo at all.

[raisinjack]

something somewhere doesn't make sense. why would the BX cause issues? Did they explain that?

[Familyman67]

they didn't state more than what I've quoted above. Quite frankly this is quite a while ago and I was so damn pi..ed at that time that I didn't dig deeper.

[sn00p]

Yeah definately interesting.... Ive run mine for a full season and more on those settings.

Anyone care to explain the difference in running the servos at the different settings? im no electronics guru so it would be nice to understand how the frequencies alter the performance?

[Hugh Mason]

i appreciate all the great info. I'm not sure exactly what to do? I'm pretty new to heli and didn't foresee frequency problems. i haven't bought cyclic servos yet. i did buy a savox SH-0262MG for the tail. Im wondering if i should try using it? I just wanted good quality metal gear servos to upgrade from stock. is there good mg servos that will work with stock 7200bx settings for the 300x? i ask because i thought savox would be a good choice and sounds like it could be really sketchy

[Familyman67]

again: I didn't mean to spoil your day - I just echoed what we learned about those servos over here on this side of the "pond". As a matter of fact many people have used them with the BeastX and the high frequencies without an issue (I also did that for a while and had no issues).

Nevertheless, for my new 300CFX (which hopefully will be available in Germany soon) I have ordered the Hitec HS5055 MG which were tested on the CFX by Chris Reibert intensely (see his review here: https://www.helifreak.com/showpost.p...9&postcount=77) - they seem to be a good replacement for the stock servos and they are equipped with metal gears.
Just from looking at them I also get the impression that they fit into the 300X plastic frame without the need for adjustments - for the Savöx, you need to cut out some of the plastic in the front servo-bay. (but this could be a misjudgement of course - I will test them on the standard 300X frame as well once I have them here)

[Hugh Mason]

No worries, you didn't spoil my day. I found out everything I wanted to know. I'm gonna go with them. Savox said keep it under 200 hertz so I'll go with the 300x default of 50 or maybe put it up to 165 hertz. I learned a lot. That's what this is all about

[65L88]

Why not use the 0257mg? They run at 200 hz and they work great on my 300X. For the record, I've used them on a 300X with the ar7200bx, an SK720 and an Ikon, with equally good results.

[andycrazy]

I also use the SH0257MG servos, I have them on my 300X and 450X (I also have a SH0264 on the tail of my 450X) I run these at 200hz (6v on the 450X) without any issues.

[horsefeetky]

revisiting an old thread for an update..

i am running 0255mg cyc and 0261mg tail on a 450x build at 6v i have it setup and no issues but not yet flown..

just checking in for any updates on issues. i set at 200hrz any advice welcome but i wonder if the issues were from those using lower voltage causing amps to be higher. at 6v they should be fine in my opinion. i have a talon 35 on it so bec should be no issue. i did find the beastx does not like a glitch buster installed it refused to boot with it plugged in so i didnt use it on this build even though several people states a glitch buster is helpful with the savox servos.

i know the jets and giant scale guys use savox and love them but always at 6v or higher

[DCflyer]

With the powerful BEC in a Talon, you shouldn't need to run the glitch buster thing.

I run SH0263's/SH0264 on mine with the internal Talon BEC at 6v - no issues and I run 3750rpm governed with 14 degrees pitch. Handles it no problem.

The 63's are 200hz servos and the 64 is a 270hz servo, but some people run them at 333hz without troubles.

I don't know what all the talk above is about having to run them at 50-60hz? That is for analogue servos. All modern digital servos are capable of 200hz or more. If there was issues in that setup it was likely due to user error or a faulty FBL unit, shorted wire somewhere, etc.

I run 0257s on a YEP using the internal BEC, I originally used these on a Beastx . At the time there were not any recommended setting for the 0257's - but the re-branded DS410 (the 0257 re-branded by Align) were recommended to be run at 60hz.

If you look at the recommendations on the Beastx SIte they still suggest low figures for some of the range

[DCflyer]

That is very strange. I'm going to say that is either very outdated or a blatant error on the person who created that.

If you look on the Savox website, the 0263/0264 are listed at 200-250hz operating frequencies.

So this is very odd indeed.

[Mikej]

Agreed - perhaps they just don't update it ..
