Hey ALL, I need some help i broke a servo horn from this MG 930 servo. Which Futaba servo horn fits and is long enough for my HK500GT Helicopter. Please Help *)

Shockflyer (50%)

Stupid, I know, but where do you get the screws &/or nuts & bolts to secure these servos? In this particular instance onto my HK-T500 Helicopter Many thanks for your constructive input.

DerClown (54%)
The screws and nuts is usually included in the helly kit.

I brought the hk500cmt and it comes with machined screws and cool aluiminuim backing plates so check your parts bags.THE t-rex 500 uses these so slightly different servos (in size regard) will fit. So ditch the stock screws to the workshop if you find the machined set

I used these servo's in my HK500GT Heli and they twitch in the neutral position just enough that they make a noise like a cricket???

stretch81 (12%)
welcome to digital servos,try the ALIGN DS650 coreless digital DAMN what a noisy bugger.

Is it suitable for a 4-meter 3-kg glider?

Straight Up (80%)
It depends on what control surface you will be using them on and how fast the glider will fly. However, my general rule is that the torque of the servos (in kg.cm) must be at least the same as the mass of the glider, so in this case a 3.0kg.cm servo is adequate for your 3.0kg glider. Ensure your control surface movements are nice and free. Don't use it for retractable undercarriage.

Sergey (73%)
Thanks. The controls are flaps, ailerons, v-tail. Thermal sailplane, electric. Cruise speed 40 km/h, maximum about 100 km/h estimated. No undercarriage. So, can it be ok?

Will these work in the HK450? And if so 3 right? What one do I need for the tail servo?

brett1984 (69%)
these are way to big for the 450, you need smaller servos, i use the HXT900 9g / 1.6kg / .12sec Micro Servo

jombo (39%)
i am using these in the 500 heli

stretch81 (12%)
NO to big for a 450 they are for 500 size

miniconverter (100%)
No they won't fit in a 450. Get some HXT900's great servo with a small price

Ken Jones (72%)
is this servo suitable for a 3mtr glider,i need to operate elevator, air brakes,and ailerons and rudder,from very small spaces. ken

kartman69 (60%)
Yes, 3.6 kg is OK for all surfaces of a 3M glider ( one servo for each aileron)

i I want to buy this servo for my 46 Katana to rudder and elevator. But everyone have used to this servo for heli. Couldn't I use to this servo for plane? Or what is the difference this servo to other servos

Wiretap (34%)
You can use this servo anywhere you like, it just happens to be the perfect size for a 500 heli.

Tunahan&Cem (77%)
Sorumu arkadas yanitlamis Mustafa Bey tesekkr ederim.Servoyu herkez heli kuyrukta kullanmis.Simdiye kadar uakta kullananla ilgili bir yorum grmedim.Bende bunu 46'lik katana modelimin elevatr ve rudder'inda kullanmak istiyorum hem hafif hemde torklu servo olabilirmi diye sormustum.

I'm thinking using this servo for the cyclic of my T-Rex 500. To use it with flybarless module i need to know its frequency.

Anyone know this frequency ?

I would like someone to help me with Turnigy MG930 Digital Metal Gear
problem.
Last month i ordeed hk 500gt full inlcuding 4 mg930.
Yesterday i finished assempling
The problem is that if i plug everything in the receiver (ar6110e)everything works exept this servo (aileron).
If during the receiver is on i unplug and plug again this servo it works ok.
But if i turn off the receiver and on again everything else works exept this servo.
I bougth a new one Futaba for the tail and i used Turnigy tail servo to replace the servo with problem.
In few words with a new servo no problem.I tryied with another receiver (ar6100e) the same problem.I changed all positions.
With new servo verything works fine.
Can you tell me what is the problem?

How do these servos compare to a HS-5245MG. With respect to Centering and accuracy. Has anybody done some testing on these servos to see what their transit time really is and the amount of torque. I ask because i punish my helis, And I am not sure as to how well these servos will last under severe pitch pumping and green bashing.

vaughan (53%)
Mine are great!!

These look like they would make a decent sailplane flap servo too, or an aileron servo if the wing was thick enough. Great price, torque and speed, metal gears.

jcaleia (47%)
Gents, latest new from HK is that they expect this servo within one to two weeks...

Just a quick note, I ordered five of these servos, four for the HK-T500. Three had 180mm leads and two 260mm leads. The 180mm leads are only just long enough to use as AIL and PIT to reach the reciever tray. So keep that in mind if you get the short leads, you will need think over your wiring path carefully. Plus the servo arms only make 15mm length on the last hole so I used some spare Futaba arms that I luckily had spare to get to 16.5mm

t3beatz (88%)
you don't really want to use these for the tail on your helicopter, they are good for the cyclic, but get a faster servo for the tail.

Anyone with comments on their HC recommended servos for the HK500. I jumped the gun by getting the Park HPX which don't fit perfectly like these.

TinuZ (34%)
I almost did as well, ordered these instead. Will let you know when they are mounted in the HK-T500... I will use a hyperion Atlas Digital on the tail

Burnaby (71%)
Decided to use the Park HPX since I already have them. Will use these on 2nd build if quality pans out.

BPGoa (97%)
the hk 500 comes with spacer mounts to allow the hpx servo to fit... i bought the hpx also:*)

Ghostfit (75%)
So the questions is on which one is better ?
The GWS HPX or the Towerpro MG930, any with both and planning to do the test ?

Ghostfit (75%)
edit: ...anyone with both and planning to do the test ?

Ghostfit (75%)
Okay, might as well reply to myself ! :)

Fitted and flew with the TP930MG, servos feels good and I don't think I'll bother swapping out to the GWS HPX.

Interesting ** the picture shows that it uses 4 mounting screws but the accompanying drawing shows two ** and hardware package appears to contain only two gromets and mounting screws. So can we trust the other specifications given?

Futter73 (64%)
I hope it has 4!!!
T-Rex 500 needs 4...

Jason5001 (4%)
It has 4.

Ghostfit (75%)
I am sorry Jason, but all of mine arrived with only 2 !
The parts in the packet are exactly as shown in the picture !

po_au (78%)
I ordered 4, all all them only come with 2 mounting gromets.

BoltFace (90%)
same here, only came with 2! ugghh

t3beatz (88%)
In a heli you don't want to use gromets anyway! you want a good fixed servo on the cyclic, the gromets make the servos flex, gromets are not needed on the clyclic...

daybyter (36%)
Are there different versions of this servo? I tried 4 different versions of futaba servo arms on 2 of my TP 930MG servos and none of them fitted. All of them had several dgs slop, as if the teeth on the servo are too thin.

Eric1180 (-53%)
Hey are these to small for a .50 heli?

tommo85 (39%)
Eric1180, yes definetly. for a 50 size eCCPM you want 3 at about 5kg torque in standard size, not a mini.
Also for a 50 size heli with mCCPM or a standard pitch lever like ThunderTiger, you want 2 * 5kg or so and one at about 10kg for pitch. all in fullsize.
