Turnigy 1800A Servo 8g/1.5kg/.10sec (3-PACK)

 Slowflyer3 14 points

The wire on this servo is 6 inches. You can use it on ailerons but remember it is for ultra light park flyers, it has a rated torque of 1500 g at 6 volts. Torque values will be less if you run 4.8 volts, which is what most small ESCs put out.

OK! I think I've discovered by myself ... I used the wrong screws! Chrome screws are to hold the housing to a support, he had to take the little black screws to screw the rotor arm to the servo ... is that I'm wrong or what is my mistake?

 Jeffrey 22 points

I used this exact same servo for the same purpose and everything works fine but the range of movement is not the greatest nor is this the smoothest servo for use with a camera gimbal.

 David 48 points

no 9 volts will burn it

 Arxangel 909 points

This one will also work on 4.8v, 5v, anything up to 6v. Speed a torque would be just slightly lower at the lower voltage though.

 jzzto 156 points

on 450 heli i would advise you to use corona MG or something like that. Corona 929 for example

 jzzto 156 points

yes, it is excellent :o)

 OldFartFlyer 1319 points

I believe so when one wants to keep costs down on an airframe. Not the best servo but not bad at the price. Compromise.

 mabaa 120 points

Yes, they come with plugs, universal for Graupner, Futaba, etc.

 dean420 68 points

yes universal

 OldFartFlyer 1319 points

Yes, already fitted using the standard wiring protocols. Will work with all systems.

 Jimbolina1 224 points

yes they do and a very good value to boot!

 jzzto 156 points

yes, they came with plugs, JR plugs and also all the servo arms you might need.

There is a little variation in the casings. Maybe some might sag or distort slightly when cooling during manufacture. I prefer to cut my housings tailored for each item. If you are purchasing, then go slightly oversize.

 MarceloMMY 93 points

its very good to 250 heli class. I use this servo in my HK 450, and to me is very good.

 OldFartFlyer 1319 points

These will fit as well as others in the same class. They are a good servo for their price. Watch out for the weak flange when fixing. It is easy to break the plastic. To make the servo lighter, the moulding is finer. I find it is easy to allow for this if you are careful.

I would suggest a set of digital servos in your helicopter.

 Dan 16 points

I had one that moved up and down without input. After some tests I found out it was affected by harmonic distortion from the motor at certain RPM's. I now fully apply power while watching the servo's to make sure the harmonics are compatible.

 msain33 19 points

They run great at 5v , 6v its the max voltage. I totally reccomend it, they re fast and powerful. I had used them with a 5v bec. I hope this was useful to you.

Work great at 5 volts.

5v is OK

 Hella-Kopterz 129 points

used them on a 450 heli for a while. strength and speed are fine at 5v(sport, scale and very mild 3d)however the servo arms provided are a bit loose and may cause recentering issues on swash applications if not checked closely. I used a bit of tin foil to tighten the servo arm fit.

Excellent work with 5-volt voltage

 MESURAT 3 points

5V is OK. I use them for my cyclic on a EXI-250. Excellent response. Wires are quite fragile, so be careful when mouintung them. (i cuted two times the wires and did shortings with big tops radio...)

 Amadeusz 8 points

I have four of them in my MPX FunCub on ailerons and flaps. They`re doing their job very well:)

 OldFartFlyer 1319 points

They will run fine at 5v. You will find that the operating arc is a little larger than say the HXT900. Response is also more than adequate in aeroplanes. Watch out for delicate flange moulding.

Spare gears are not supplied in the purchase pack. You can obtain spares in the usual way when you bust something - remove the part, measure and then check your suppliers etc if your **** box is empty. Or you could choose to replace the servo.

it depends on the size of your model, i have an easy glider pro and have used these servos with no problems

 mrfourtysevenman 128 points

well i dont see why not. do whatever you want but you should get the blue metal gear servo. i forget the name but it is 5 dollars.

in a 450 size heli it works well, but the solder joint of the servo cable has to be resoldered and fixed with glue.

Is a very good servo who does not want to spend too much, I bought 4 of these, use 3 in a cyclic and 1 in the tail, is helping me very well...

 punisher 25 points

For the tail servo is not the best ,for the swasplat is the best for 450 heli .

 Maksim 129 points

I"m not recommend it for tail not for heli at all

 Winston 12 points

Bom produto!

 Brutus315 26 points

This servo should not be used in a 450 heli. It's to weak for cyclic and to slow for the tail. It's a fine servo. I have 6 but I use them for lite duty like ailerons in a foamy. They could work in a 250 or smaller heli.

 Uberfest 31 points

recomendo apenas aeros eletricos pequenos

 OldFartFlyer 1319 points

Yes. I've done that many times. No problems. Good arc. I'm reinstalling one that has already given over 90 hours of flying service. Very reliable. The key is to install and set up CORRECTLY.

 Wilhelm 255 points

No. These are standard 8g analog servos with a bit higher quality than hxt900 or similar. But they aren't digital. Wilhelm

 Juiced 5 points

Thanks, so I should not use my radio om 11ms with htese servo's but the normal 20 ms??

 Wilhelm 255 points

I never changed anything. I use digital and analog Servos with the standard settings of my receiver. Never had issues. Wilhelm

 ANLUCAS 147 points

No they are analog.

 Bjarne K 99 points

nope analog.

 mario 318 points

No, this servos are not digital, this are analog servos. i use them on my 2 m sailplane with a hitec eclipse 7 radio on 72 mhz, andt hey work very nice, centers good and don't have any jitters.

No, these are not. They are regular analogue micro servos and don't have the accuracy of the digital ones, although they are quite accurate.

 __buzz 308 points

hi there hobby king is right it is 1.7kg.

 Wilhelm 255 points

But I would never use these small servos on 1,7kg/cm...small planes with about 800g and 1m wingspan, you can use it, but for your safety no bigger planes. I use it on a singlewing of about 140cm wingspan as aileron servos it works but the plane isn't really fast so the forces are low.

 Mangirdas 5 points

Actually, none of these are really correct, the real torque is about 1.3 kg/cm, but it is more than enough for a 1.5 meter plane or even bigger, but if you are going with something bigger than 2 meters you should consider buying more powerful servos.

 OldFartFlyer 1319 points

Torque varies in accordance with both current and voltage. It all depends on how much power you put into the thing and how constant your supply remains through your flight. Let's be fair to the little beggars. They're a good servo and I run mine at 5.5v constant. They are slightly lighter than the legendary HXT900, they are a little quieter. They are definitely a little stronger. They will last as long as others in the same price range, too. I have apair of these operating the flaps of a

 FelixRC 40 points

Because of packaging......ect

 ____3D 21 points

don't know but they're so cheap that this shouldn't be a problem!

 bothal3 2053 points

It is for 3 x 8 g = 24 g packaging.

 TheNightstalker 21 points

because of the packaging weight *) For shipping the TOTAL WEIGHT has to be calculated so there's a packaging weight AND the items weight on every product page. Hope I could help

Can anybody tell me where to buy longer and stronger servoarms?.

 Mangirdas 5 points

It's the packaging and wires that add weight.

 Aircraft 4 points

because the package servos weight 75g

 OldFartFlyer 1319 points

There are three of the little fellas in there. Plus packing. And yes, it is still a little lighter than 75g. Fair question.

 kwack chil sick 50 points

hi power speed

 cl ment 81 points

I think you can use HXT900's ones, but I'm not sure... this servo seems to be the same as Esky 9g, so I would say that you can use esky gears.

 __buzz 308 points

why not just buy a new servo they are really cheap

 FelixRC 40 points

Been looking for replacement gears myself, but rather opted for new servos...... they were cheap enough

Hi, the servo works perfectly with 4.8 V. As I know, speed and torque will be a little decreased.

And do they work with 1S (3.7V) ?

they are doing great work on 4V in my plane as well

Just put mine in a 250 GT and they are smooth and fast, center well and weigh in under 7grams. They are better than the hxt 900 which I have had in my flasher 450 for about 80 flights. They appear to have better resolution. Fantastic servo will be buying these from know on. And they are dirt cheap. You have to love HC........The hxt900 are good but these are better!

 mariube 36 points

They have better resolution than the hxt900. However they have a smaller output spline and the mounting tabs are much thinner and quite brittle, so it's maybe not so robust.

 Elli 37 points

Those servos are comparable to the HXT500. 0.2 gram heavier than the HXT500, and 4 gram lighter than the HXT900. They have much more power and streps than the HXT500. However, they are not nearly as strong as the HXT900, which is expected since they are in lower weight class. You cannot use those in applications that require the HXT900, they do not have the same power.

 OldFartFlyer 1319 points

No, not better, just different. I use both and place them according to the respective strengths. These are lighter, a bit quieter, they have a slightly greater operational arc (effective push pull), and they might have a slightly stronger push. The HXT is cheaper, it has a smash-proof and rugged casing that can be glued, crushed, thumped and abused yet still perform. It can be ripped out of one such installation, cleaned up and then banged somewhere else. You can set it and forget it. In co
