Hi Patrick, it depends on.. well nobody knows. I life in Switzerland and the Shippings with International Airmail (Always 500g) takes between 6 Days and 32 Days. So no one can say an exact amount of time.. it depends on your luck! :)

I am also looking for the servo horns that will fit the "DS919MG" servo.
Is this a align, futaba, hitec type?
Product Specialist 5:
Let me check
Product Specialist 5:
It seems that corona is using their own servo spline and popular brand horns doesn't fit.
do you have corona servo horns in stock?
Product Specialist 5:
No, we do not have them...
Hi christian, As long as it meets the size and torque requirement for the car it will work fine. If you're replacing a bad servo in your car, measure the old one to ensure that this is the right size. It will definitely have as much torque as one the same size that came with the car. Cheers, EA!
Drifting requires high torque servos so I would recommend to go for something stronger which can handle above 2.5kg of torque.and I agree ensure you check specifications sheet and match the size of servo or it won't fit in your Car.
I purchased this motor but its not starting
i used red( ) brown(-) and orange (pulse) color convention of the servo wire
Am i right with this color code??
and yes then why even I applying the 500Hz 50% duty cycle signal and my motor is not running ??
Corona 919MG Metal Gear Servo 1.7kg/ 12.5g/ 0.06sec
I want to know the max and min pulse width for this motor for safe operation.
and different pulse width for different angle.
hypothetical example 1.5ms for center position
what pulse width should i apply to motor to keep it in center position and what pulse width should i apply to rotate motor in anticlockwise direction.
You guys think this will work on the turnigy 3 axis camera mount/gimball? I think all the specs are great but the only think that would concern me is the metal gears. I've heard members say use plastic gear for smoothness and yet hobby king says use metal gear for smoothness (regarding camera mounts) what u guys inputs please. The camera is only a out 1lb = -.5kg. Thank you for your feedback
I agree with HellyFlyer, Metal geared servos are much more reliable than plastic geared servos.
Since you will use just to move a camera gimbal I dont think that a good plastic servo (Usually cheaper) will rip off the teeths of the gears.
You can buy HXT900 9g / 1.6kg / .12sec Micro Servo that is cheapear than corona and the load is almost the same. I use this one on retract landing gear and they hold up flawless my plane weight when landing
Thank you for the information, I will buy these ones. I have had the HXT900 and they worked good (when they worked) but found several of them in the past to be faulty. I'm gonna assume that these coronas are going to probably be of better quality..
Ok i read alot of good about the DS919MG i know its digital but now is the next question. I bought a NEW Razor and have a Trex goth are 450 sers , can I use them for ALL Servos on both helis? I bought 10 of them here and had planed replacing them on both helis and replacing the ones on both helis with the DS919MG . Will this work and is it a good Idea? If so why if not why. Im new to the repair or servo thing.
I really dont`think that any negative answear...
At my interpretation, you can use successfully at both Helicopters withou any problem.
I use myself these servos at Cyclic and Rudder on all my 450 Helicopters.
Well im not going out yet for the full tilt 3d flying I just wanted something more stable than what came with my NEW Erazor 450 and my USED Trex 450 they both have Analog servos and not into the heavy 3d flight right now just want them to fly safe and not encounter any crashes due to a soft servo. Thanks everyone for the input will try and fly . After all the fun of it all is the flight time but then there is some fun in the rebuilding and learning more about your craft as long as the cost don't place you in the poor house.
the 250 its not a big heli, go for an ESC with 6v bec or use one SBEC (ESC Switched bec), some of the SBEC's have dual voltage. beware that those servos cause glitch with most analogue servos, ferrite rings worked for me.
Ok now Im really confused...I asked questions and some others said this servo would work well on the tail...but now Im reading that it will not....so whats up fellas???....Im using HXT900 on the cyclic....So which way is up???...can i get some help here???
Hi Antonio, If you read the negative comments carefully, you'll notice that most of the problems have occurred where people have mixed these (digital) servos with analog servos. Any time you have big discrepancies between servo types it drives other devices (i.e. gyros) crazy. These are great servos ... fast, strong, and cheap. Just make sure you use ALL DIGITAL servos. Cheers, EA
simple answer is that , you can use it on the tail but it will disturbs your cyclic servos because these (hxt900) are analog, so to prevent taht disturbance simply Clip On Soft Ferrite Rings on to the wire of corona 919mg and then you are gonna love this servo on tail as it is very fast. here is the product id for ferrite rings SKU: 343000001
and also it is good to put one ferrite ring on gyro wire too but it's not necessary. I myself is going to use 919mg on tail with hxt900s on cyclic. as i have solved the problem which was occurring earlier ( jumping cyclic servos when trying to use 919mg on tail)
Hi Antonio and Ibrahim2012, I want to clear up one thing about these servos. They are digital, not analog. Corona uses a very simple system for the part numbers on their various servos. Their digital servos always have a "DS" prefix, as in "digital servo." Their analog servos always have a "CS" prefix, as in "Corona servo" or "conventional servo", I'm not sure which. These are "DS919MG" servos, as in "digital servos, model 919, metal gear. The fact that HobbyKing didn't explicitly state that they are digital doesn't make them analog, it just makes HobbyKing look sloppy in how they write their descriptions. Cheers, EA
Hi Antonio and Ibrahim2012, A quick follow-up on my previous message. I just went to Corona's website to verify that this is digital with 100 percent certainty. It is digital, it's listed under their digital servos, and their is actually an analog version of this servo listed under their analog servos as a ... wait for it ... model CS919MG analog servo. Cheers, EA
Hi Ibrahim, Sorry if it seemed like I was having a go at you. I realized after I posted that you had been referring to your HXT900 servos when you said "these are analog". I actually started reading the older posts on this page and kept seeing various people state that these are analog servos, so I was on a roll clearing up this issue when I got to your post. Pulled the trigger too quickly. Sorry about that! Cheers, EA
Hi ElectricAussie, No bro there is no need to say sorry, because it does not seemed to me that you were having a go at me brother, I was just saying that i own one 919mg digital one, cos as you said before that there are 919mg analog servos too about which you were absolutely right bro. In your reply to me there was nothing wrong bro *-) .Have a nice day.
Excelente servo para cauda de helicopteros da classe 450, utilizo um no meu com o gyro hk401b e trava perfeitamente, vejam as fotos do meu heli em files em eletric helicopter hk 450gtpro belt drive.
É* um servo digital, metal gear e de alta velocidade.
Yes, but people have reported interference with combining digital and analogue servos, so maybe dont use it if using analogue cyclic's. Remember to set gyro delay for digital servo (off, or in digital mode)
I can't believe this "it's digital" "no, it's analog" argument is still going on. Corona uses a very simple system for the part numbers on their various servos. Their digital servos always have a "DS" prefix, as in "digital servo." Their analog servos always have a "CS" prefix, as in "Corona servo" or "conventional servo", I'm not sure which.

It's listed under their digital servos, and there is actually an analog version of this servo listed under their analog servos as a ... wait for it ... model CS919MG analog servo. Cheers, EA
If you guys read the item description you will see the model number as: ds919mg. and yes is digital.
it is fast but the case breaks easily, causes glitch on the other servos, and the bearing should be better, but that's expected for such a low price.
I manage to solve the glitch with ferrite rings and a capacitor on the receiver.
It is a digital servo a digital servo is 10 times faster than an analog servo, this results in a much quicker response from the beginning with the servo developing all the rated torque 1 degree off of the center point.

I recently installed one of these on the tail of my HK450V2 paired with the HK401B gyro. The torque and speed are good, and the servo centers pretty good for a MG servo. The Align DS4 servo arms also work on this servo so that is a bonus. I will be purchasing more of these servos as soon as they come back into stock. Very good product HK!
