you can enter on google the kg's of torque and type convert to ounces and press enter and it should do the math for you.
example: 30 kg convert to ounces

I had a hs 81 servo in my sig mess 109 on rudder and stripped it out. I replaced with a turnigy 1160 I bought five for the price of a hitec. working great. I have a hxt900 for throttle on my 96inch davis d1w gas powered. I have hxt12's on my control surfaces they are not fast but for the Davis it will be fine it is a parasol and does not fly fast anyway. Just big! I use lots of those "Off Brand" servoes with a great degree of success. I will continue do do so when I can buy 5 for 1 why not? I can do more airplanes for the same amount of money. I have hxt 900's on all surfaces in a chipmunk and they work just fine.

The one person that stated they get rebranded is correct. I won't hesitate to use them.

Yes you can do that, but it DOES NOT convert Kg/CM to Oz/In correctly so be careful.

e.g. here are accurate conversions.

1 kg/cm= 13.8oz/in
2 kg/cm=27.7 oz/in
5 kg/cm= 69.4 oz/in
10 kg/cm = 138.8 oz/in
15 kg/cm = 208.3 oz/in
17 kg/cm = 236.1 oz/in
20 kg/cm = 277.7 oz/in

the manual for my great planes .25 spitfire say to use a minimun servo with 35oz/in torque my hextronik mg14 servos im ordering for this plane will run that at 6 volt but wont quite run that at 4.8 volt. just out of curosity when manuals state a minimum reequirement do they stat highball figures to insure u wont have probs or do they state more or less the absolute bare minimum as in if u dont use this much torque ur plane is toast kind of thing? i would prefere to run my mg14's at 4.8 volt casue i dot really wanna have to go buy a nmew pack when i have spares kicking aorund in 4.8 volt.

Plane manuals normally state a number with a decent margin for error.

The manufacturer does not know how you are going to set up your plane, so they err on the side of caution.

If you set things up for maximum mechanical advantage, the chances are you would have NO problems with lesser torque servos which are less than the recommended specs...

However it is best to be right in the middle or greater so to speak, to avoid potential problems...

The servo you are looking at is a bit above a micro size servo, but not quite at the mini-size range.

Micro servos go from about 6g to 13g or so in weight while the Mini's are above this.

Why not look at the 16g servos instead?

Your plane should be able to take servos up to 22g weight.

well i would liek to stay with the hextronic servos and i would like to stay with the micro size that the manual for the plane recommends. i just want to know casue its speced at a 35 oz/in servo and im a newbie when it comes to electronics i want to know if my mg14's running 4.8volt at 30.3oz/in torque will be okay if i happen to run at full bpore throttle and snap a tight turn. or tight loop o whatnot. the lasst thing i want is to strip out a gear opr something.

Yes you could use those w/o problems.

But again there is no reason you could not use slightly higher torque Hextronic servos, e.g. the 15g+ servos they sell.

The price difference is minimal anyway, and sizewise they are identical.

well yes u are right in that regard only thing is when they stat getting into 20 some dollars for a servo by the time i convert my canadian to american money plus pay shipping i might as well just put futaba high torques into it. and im kind of going for a money savings this time around thats why i was wanting to know if i would be safe with the mg14s. but believe me friend i totally understand what u are saying and i usuallly buy the best stuff. but with money the way it is and the economy effecting me i gotta start thinking other options right now,lol!

Go for it, but to play it safe work for maximum mechanical advantage.

To get this:

Set your Transmitter servo endpoints as high as it will go on the TX ( I use 150% on my JR radios ).

Move the linkage connection on the servo horn in at least one hole over what is recommended or if possible all the way in ( towards the center screw hole ).

Move the linkage connection the the control surface horn out at least one hole more than is recommended, or if possible all the way out.

Adjust the linkages and hole positions until you obtain the indicated surface deflection amounts.

This will give you increased holding power, better servo resolution and control, while demanding less from the servos themselves.

Turn up your TX's expo for even better fine control around stick center.

hey thnaks for that info i was wondeing what was meant buy mechanical advantage.. so if my thinking is right making those adjustments should prolly give me maximum throws on everything shouldnt it. i could be wrong casue i know if u adjust one way ona servo hole and control horn youl get more or less throw on control serface

and i have a spektrum dx6i. when u say turn up the expo do u mean to go into the negative side on the spektrum to make it more twitchy near center?

Nope the opposite.

You want the Expo to be about 50% for your high rates and maybe 35% for your low.

Increasing "mechanical advantage" is much like using a longer lever to move a boulder.

You can lift a larger load, because you are moving the lever over a bigger arc, to move the load a smaller distance.

Increasing mechanical advantage normally DECREASES the total amount of control surface movement you have available. You are sacrificing movement for holding power.

However by increasing the distance the servos move via the TX settings you offset that.

So you are trying to end up with the recommended control surface movements, but you are doing so while letting the servos exert the most power and leverage on the control surface.

You will not get "maximum" throws ( in other words everything that would be possible if you went the other way... ), but you should have no problems obtaining the RECOMMENDED throws or control surface movement amounts....

hey thanks for explaining that to me in easy terms,lol. iunderstand what u are saying now and it makes perfect sense. i will have to remember to try and do that on all my planes now. hey i dont suppose u can tell me what a good motor for s sundowner 50 is could ya. its range is a 2 stroke 46-52..my father wants me to put in a super tiger 51 but it dosnt turn as large a prop as i want it to. the recommended top engine from hangar 9 is the evolution 52nx. i am liking this motor but i dont know anything about the evolution motors except that there .46 wasx a piece of junk. and i cant seem to find much info on the 52nx or the 60nx. theother option i was thinking was to put in an os .55ax casue they are known to be great motors. but upon readng up i have been reading a lot of people have been having a lot of finicky tuning issues wioth that .55ax especially running pitts mufflers which i really want to run on the sundowner. but any ideas for motors u or anyone may have would be great. lol keep in mind im not wanting to go crazy liek with ys engines and what not just sopejthing that will hold a setting and still give me great performance should i ever decide to really open it up when i get better at flying.

oh and yeah all my planes are set up with +35 expo on low and +50 on high already. make thigns a little easier to fly!
