can this be used on a hk450tt v2 fbl tail/rudder?
mattman0182  11 points - 4/21/2013
 
Love this thing! It is the best possible servo for the Traxxas Mini series. Way better than stock.
 Justin 1 points
What all did you do to make it fit? I get mine in 2 days for my mini e-revo. Any helpful tips or advice?
 mattman0182 11 points
It went right into the place the same as the stock. I did have to make a mod though to the plastic piece that turns the servo. I drilled out the hole a little but so the traxxas screw would fit through. I cut off the access plastic because there was not enough room for it to turn all the way. Took about a half hour for me to install, and I am very slow.

Great metalgear-servo and it's very strong and relaiable. Good centering and no slack. For my use that's very important. I use it for the elevator on my Cobra dynamic soaring model with great results. The bird has an all up weight of 5kg!
Bektorkhan  13 points - 4/17/2013
 
I managed to crash with my tricopter and the first alu gear broke. But turning it 180 and drill a new 1.2mm hole for the stopper pin, and it's in business again. Great strong and fast servo with two life's.

Hy chad It' s a great servo very strong !! I put it on funjet ultra with a big combo engine !! speed 241 km/h and the servo is good for hard condition

Whats the difference between this one and the TGY-393V HV model besides the price and the color?
Fangz187  3 points - 1/28/2013
 
I run this servo in all my Traxxas 1/16 vehicles. It blows any other servo I have tried out of the water. And on my 1/16 Revo I am running dual servos and it is amazing. I recommend this servo to all my friends that have a 1/16 Traxxas vehicle. It's the first thing I change if I get another 1/16 car. And the price and quality is well worth the wait to get it. I hope they start carrying these in the states soon so wait time is less. Plain and simply the best servo for Traxxas 1/16 scale cars and trucks!!!'
 Jasper 1 points
Why do you run dual servo in a merv?
Are they waterproof or resistant
Matthew  7 points - 1/21/2013
 
Works excellent in Traxxas Mini 1/16 REVOs. I had to trim the little gussets off the top of the mounting plate since the servo mounts upside down in a 1/16 REVO. I also enlarged the mounting holes in the servo slightly to fit in the servo guard/cage/alignment block perfectly.

Hey do this servo have coreless motor
 jimmy 4 points
no i dont think so but it does have a brushless motor i believe.
 Matthew 7 points
The package it comes in says "coreless".

the servo horn on the 1 16 traxxas vehicles fits right on.
 Umar 6 points
you can use the horn that is supplied with this servo, just make sure to zero the servo correctly. my advice is to use a hole in the turnigy horn which is of the same length as the stock horn.
Lucas  3 points - 12/11/2012
 
Does it fit on Monster Beatle? I'm from Brazil. It took more than a month to my car get here, and I played only 5 minutes with it. I've hit a wall and the servo died. Now I'm looking for a stronger replacement. Does it fit?
 maverick51 47 points
hello I think this servo is litle small for car, you shoud prefer 35-40g servo
mpjf01  11 points - 11/21/2012
 
Where can I get more servo horns that fit this servo, same as the ones that came with it?
 mpjf01 11 points
Just worked out that futaba horns fit, unfortunately HK don't seem to have any normal sized horns.

I was wondering anyone use these in a 500 HK or 550 Hk Heli I have been waiting for a Looong time to buy the 500 heli and I am just going to do it for a winter project,would loike these for the cyclic or your suggestions Thanks !!!!
 Jonas 9 points
Have used this servo for trottling a 21 glowengine offshore competition boat for 2 years, and also this years World Championchip. A precis, robust and exelent servo. I will do the jobb in your heli.
 Jorge 12 points
These DO NOT fit the HK500 or the HK550. For those birds, you might want to try the TGY-306G-HV servos instead.
 muchomor84 174 points
God! TGY-306G-HV are 450 class size! I'm sure cause I do have them on swash on my 450Pro!
 Tryin2fly 263 points
Thanks Jorge,Jonas,much84 for the input but I still cant seem to find a servo that I like and that is "IN STOCK" at the USA house w/the 500 bird I might just give up and move on to a diffrent winter project!I really like HK 95%of my orders go to them but they should have there s#$t togther by now in the USA house but they don't they are going to loose alot of money if they havent already !!!!
 Kal-Pol 1 points
Well, in my my opinion best swash 500class servo is Hitec HS-5245MG. Couple of my friends use them their 500s and they do job well. Other good (or even better because of coreless motor) servo is Savox 1250MG. It's same servo as Align DS510M. Regarding servos from US warehouse I'm curious if Corona DS329HV is worht anything. But anyway, safest option is to buy HS-5245MG or Savox 1250MG.
 muchomor84 174 points
Heh, above post I wrote myself but from other login LOL *) Well as i wrote Tryin2fly, those two servos are best. Although srom INTL warehouse you can buy HK28013DMG. There are no other "safe" servos. Maybe that Corona would work but I'm not sure for reliability of it.
Christoffer  1 points - 10/14/2012
 
I have buy 2 of this servos for my funjet ultra,, one of them go smoth and easy to move when i take in servohorn but the other is locked and not move. both works with the reciver and radio. why are they different, and can i use it in a fast 2500watt funjet/ regards Christoffer
 Trond M 24 points
Definitely ok for the Funjet Ultra. Why one can be moved easily and one cannot ,well try switching off your RX while the unmoveable servo arm is out of zero. see if the same still apply. I would not recommend to use any force on a unpowered servo though. If both work when connected, well thats what they will be when you fly. After some use the gears wear in a bit and let you move the rudder surfaces manually, if thats what you like to do. I have 2 of these, both move easily when off power. They
 muchomor84 174 points
Hi Trond M, what about long term test of this servo? Are they gain slope in gears? I'm looking for servo which has slope like HS-5085MG or smaller, being faster than Hitec.
Whitman Flyer  21 points - 9/27/2012
 
What is the stall current draw? Is it more than 1 amp per servo? Has anyone tested these? Thanks. Chris
 Trond M 24 points
Had a search around the net, found nothing for this servo. BUT if you have a Voltmeter, attach to and -, connect your rx abd tx, and move the stick vigorously from extreme to extreme. According to literature an electric motor consumes the most power when stalled/changing direction. If you are brave, you can stall the servo arm whilst measuring the voltage. Should be ok for very short time. Good luck

Is there any replacement gear pack? It's not a cheap servo so it would be great to find replacements for this servo. I have one with the main gear broken (the bigger one).
 Jim 8 points
HK currently does not have a replacement gear pack.

HK doesn't sell replacement gears for this servo so most likely you have to buy a new one

BEST ANSWER CREDIT AWARDED
 Jim 8 points
This servvo as well as the BlueBird 390, are direct drop-ins for the Traxxas 1/16th vehicles. They even use the Traxxas servo horn.
 michelle 121 points
yes perfect fit, no mods required great servo too
 Matthew 3 points
The servo can fit 1/16 Traxxas vehicles without modification, however you may want to file down the tabs on the mounting flange as I did. This way the servo will sit low, just like the stock unit. As stated, the Traxxas servo horn fits perfectly on this. I've been running this unit longer than any of the stock units survived. Highly recommended over the Traxxas 2080 servo.

Servo monté sur Funjet Ultra avec 2800 W les servos resistent!!!
 muchomor84 174 points
They are like HS-81/82MG size, so won't fit. Try TGY-306G or 306G-HV. I use the on my 450Pro. God damn good servos!
 muchomor84 174 points
I forgot mention that for tail I made an carbon adapter for this servo. I use them both for swash and tail at 6V. They're perfect!
 muchomor84 174 points
If you don't want to make an adapter, buy 3688HB, I previously use that servo on tail and that was good.

I was wondering if anyone knows how much power draw these servos have. I run duel 7.2v 1200 mah NiMH's in my 1/16 traxxas summit. And can it cause the motor to run hot?

Thanks.

 Kyle 12 points
I have one of these and I currently run with only one 1200Mah NiMH battery. My motor does not run very hot at all. It seems like the servo takes hardly any power.
BEST ANSWER CREDIT AWARDED

Your motor will not run any hotter using this servo. Some people recommend using a BEC, but I have not had ANY problems with it plugged directly into the receiver.

Hi I ordered one of these a week ago and havent heard a thing from HK, ive asked several times in customer support and gotten no replies. The order status has not changed in a week, what gives?

What shipping did you choose and what country are you in? I have had packages that took a little over a week and the tracking numbers didn't work. They all get here, sometimes international shipping is funky though.

Hi,

I am looking at getting one of these to replace traxxas e revo 1/16 steering servo. Has anybody else tried this combo as it appears to fit from dimensions provided? Is there an aluminium horn option to suit?
 Nikolay 3 points
Just ordered mine yesterday. Looking at the Traxxas forums this is the best replacement for the MERV (Mini E-Revo Vxl). On the forums they say it fits fine, but if you want to there are two tabs that you can cut off to get a perfect fit.
 Justin 12 points
Yes, I am running one on my 1/16 E-Revo and it is awesome. I did grind the two tabs off so that it fits flush.
 Kyle 12 points
Mine fit perfectly when I got it... It only took 15 minutes to install and I did no mods at all. Great little servo. Been using it for 3 months now and no problems at all yet.
 apinck 4 points
Im waiting on mine for my 1/16 summit. I have gone through about 7 of the stock 2080 servos. I running one of the Hi-Tech servos right now, but it was a pain in ther butt to mount. I hope this is the last servo I need to purchase for a loooong time.
 vooma 3 points
I got mine 3 days ago and it took me around 5 min to install it on my merv and i love it you dont need to cut anything the taps just makes your servo guard around 1mm taller Its ether this servo or hi tech if you dont mind paying extra

Does it work at 6.6V?
 petr9999 9 points
no, it will burn
 Justin 42 points
It should. It's a really well built servo! I love my two they work perfect!
 Aleksandr 1 points
Justin, how long you use them on 6.6v ? I want to connect A123 (LiFePo4) 2 cells to Futaba R-149 DP 35 Mhz. And plug this servos into this receiver. Does it work stable for long time?
 Justin 42 points
They warm up pretty good on 6.6v. If they are going to be used for long periods of time under heavy loads then I would just get a simple $2 bec. They are kind of pricey servos and is hate for them to burn out on you. But its your call. They do work on 6.6v but I dont use them on 6.6 because of fear of burning them out so I have a ubec.

HK-401B is S**T, try Assan GA-250, much better (almost as good as Spartan Quark). Anyway this servo is to slow for tail. Find sth below 0.08s.

Quark is much better then Assan and I think I'll change head to fbl and buy microbeast...

Super smooth flow, and easy to install. A MUST for replacing the stock 2080 servo on the 1/16 Traxxas vehicles. I have a 1/16 summit that I am pretty rough on, and this little servo puts up with the abuse!

Those who write that this servo has little slop or no slop in gear are crazy! I've bought 4 pcs of them and all have terrible play in gears. It is so big that won't even try to install them on Bruckmann MX-2 1,3m. Now I've ordered TGY-778MG. I hope they have same little play in gears as TGY-306G in my 450 heli. Although price is too high, 778MG are cheaper and should be better. Defenetely not recommended. Waste of money as most of Bluebird servos.
