hey all im looking at ordering some servos out of china to put in a house of balsa 1 1/2 a mustang but thought i would ask your opinion i am looking at ordering some hextronic 9gram micro servos rated at 1.6 kg of torque..will these servos be good for a plane this size and for that matter would this size servo be okay to use in any .25 size plane application?

i am also looking at ordering some hextronix 55 gram servos rated at 10kg of torque.these are standard size metal geared servos and i am wondering if these would be good to put into a hangar 9 sundowner 50 and perhaps my top flight 60 size p-47 thunderbolt.. these servos are very cheap top buy but i am reading nothing but good things about them. im only have kg torque ratings and not ounce ratings since its a metric website...any help with these servos would be great or if anyone is using them can give me some info on the micros and standard servos and what pplications i am okay to use them in would be very helpful!

I don't know the availability of products from the US, say Tower Hobbies, in Canada, but for the price of the Airtronics and Futaba standard servos being right about $10.00 (US), I, personally, would opt for those. They are great servos and, for the price, well, it's tough to beat.

CGr.

the ratio is about 13.88... 10kg gives you over 130oz which is plenty for even up to 25% scale planes... I use to use those hextronics 9g servos in all my foamy applications as well as E-flight mini Showtime 4D balsa plane... I would say it can be used in all planes weighing less than 1.2kg in total... or 42oz...

hey thanks for the info. i see theres a couple power hd brand servos out ofseling on this site out of china.and if i remember correctly they even say made in tiawan on them. a regular metal gear is opnly 11 bucks with if i remember right 118 oz of torque and then the even have digital metal gear ones for 24 bucks. i have read nothing but good reviews bout them on the site. andthe way i see it if u were to factor in the insane markup to the domestic market that 10 dollar setvo probably would end up being a 30 or 35 dollar servo in north america anyway. lol. hell half the stuff we buy now is just made in china and rebadged for domestic anyway. figure might as well give some of this stuff a try since i hate paying 25 bucks for a futaba mini hgh torque servo. as good as they are.

there is nothing wrong with powerHD servos... I have used the 9001MG (metal geared) ones for over a year now... no problems... they have a real nice big one 17kg (246oz) of torque for real cheap also... 15001MG I think... but I like the brand, I have stopped buying Hitec which is crazy expensive... their micro servos should be just as good...

what is the website i need some new servos

Some U.S. Vendors are now picking up the PowerHD's... e.g. Troybuiltmodels, etc.

I picked some digital metal gear 17kg torque servos up for a 50cc plane... fantastic servos for the price.

Yes, buy them, save your money. I have used the HXT5010, which are the same as the TowerPro 5010. They have great speed, and torque and are about half the price of the standard name brand servos(Hitec 311) and have ball-bearings too. The Hextronic 9g servos are a really good buy too, use them up to as Switch said, about 1.2 kg and you are set.
Have fun,
Curtis

Yup, I too have had GREAT luck with the HXT's and the 5010's are practically overkill for most Sport .40-.90 sized planes.

ahh u guys have no idea how great it is to hear what u are telling me. aside from the hxts how do u guys feel about the power hd brand servos?

I have also used a bunch of those 9g Hextronics servos and they have worked great. I don't know that I would use them on control surfaces for a glow plane, but for small electrics and for throttle servos I have had good luck with them.

oh and to the fellow who wanted toknow what the website is it is www.hobbyking.com its out of china but ma there are sweet sweet prices on there

I only have three of the smaller PowerHD servos and they are very new. They seem to work fine and I have confidence in them. Hopefully someone else will chime in too. Also, grab a couple of those HXT5010's for your sundowner and thunderbolt. I don't think you will go wrong.
Curtis

Yup, I'm using the Power HD's on my gassers. Excellent servos.

those hxt5010's....is it a big deal that they are not metal geared i know my plane requires a 72 ounce torque servo and those hxts are like 118 ounce or more but im guessing the resin gears in them should strip unless u get above the specified torque rating???

No it's not a big deal at all.

As a matter of fact metal gears tend to wear more quickly than nylon gears.

The 5010's produce about 130oz/in of torque @ 6v or so. It takes a good amount of force over this to cause the gear to strip.

So far I haven't stripped a single servo with well over a hundred purchased.

excellent! great to know considering there only like 5 bucks a piece versus 30 bucks a piece,lol....would u be able to tell me whaqt a good servo would be of the hxts or the power hd's that would replace a higher torque mini servo for a great planes .25 spitfire? thats the only servo im having trouble nailing down because im not good with the measurments and id hate to order ones that were to big or way to small. i know that the hxt900's would be to small and way to little torque plus there a micro size so i if anyone can help me pick a good dependable mini size that would be perfect.

If you are going to use submicro servo's on a nitro model I would get some with metal gears. I strip the nylon ones all the time.-BW

oops my mistake i dint mean to say one that would replace a high torque micro i just meant if ayone could tell me what hxt or power hd servo would be the equivilant to a futaba s3115 mini high torque casue i hate paying 20 bucks for those things

<span class="headingb"><font color="#336699" face="Tahoma">would the Hextronik MG-14 14g/2.2kg/0.11sec aircraft servo be a good strong reliable one to use for a .25 spitfire instead of the futaba s3115s</font></span>

Those MG14's are great servos. They are a lot like the Hitec HS-81's. They are super quick and very powerful. I would never hessitate to put them on a .25 spit. I have two working the ailerons on my .46 giles.

Curtis
P.S. I was looking for the link before I saw you actually asked about them.

ahh this has beena great day for me im just sitting here smiling like crazy as to how much money i am now going to save. and now i found all the 3 sizes of hxt servos i need for any application i will ever need. got the hxt900's for ahything amaller then .25 so im hoping i can use the 900;s in my little house of balsa .10 mustang 1 1/2 . il use the hxt5010's in my sundowner and my winter build thunderbolt and il use the mg14's in anything .25 size..god im literally laughing..lol..heres hoping they dont crap out and take my plane into the dirt,lol. oh um i would assume those hxt5010's would also work great in a sundowner formula 1, 80inch, 25% though i might have to use 2 per wing half i believe.

You know, you could use the 900's in the mustang, but you might find that they just don't have the power to hold the surfaces under stress (like a hard turn at speed). So even if they work well at slow speed, they might not be a good fit. I know you are into saving money, and believe me, I am too, but you might want to pick up a few more MG14's for the mustang. Either that, or look at the ratings and feedback of the servos in the Mini Servo 11-20 gram category on HK. There are several in the 17 -19 gram weight range that have over 2 kg torque and are fast.
Good luck,
Curtis

oh ok well thaqnks for letting me know i just thought id use the 900's becasue i really didnt think that little 1 1/2a mustang would creat that much strain on the controls. but ur advise seems sound and i have no probs getting 4 more of the mg14's there still dirt cheap to buy as far as im concerned..lol..12 bucks still isnt 25 or 30

oh and if ud happen to know. a buddy of mine gave me a chinese extra 330l arf .15 size kit. my os .25 is to big to cram into the cowl of it but im wondering if maybe a asp or magnum 21 would fit. i dont really know what the size difference between an os .25 and magnum .21 are
