HSG 5084 MG Hitec for tail servo?

[cheguazam]

Hi,
I might be missing the thread regarding this servo. Does anybody use Hitec HSG 5084 MG for Trex 450 tail servo with GY401? How was it? I'm considering to get one for my trex, I knew Futaba 9257 is the best for the job but too pricey for the moment. Pls help me to make decision..TQ

Hitec looks good. I haven't tried one, but wouldn't hestiate to do so, if I was inteh mnarket for a tail servo.

Most of trex 450 owner uses Futaba 9257, it is said to be the most reliable for the job, but since i can get 5084 for half of the price, (after discount) i might give it a try. Currently i'm into medium 3D flying. Crashed 3 times because of the tail failure, got fed up. In case if you were wondering what tail servo i am using right now.. it's Tower Pro.. LOL.. Comes with the combo pack.. I'm thinking of getting a 5084 for the tail and 3 hs65hb for cyclic, how does it sound?

[HELINHAWAII]

I run a 5084MG on my T250 and it is a vast improvement over the tail servo that come stock in the combo. I don't see why you couldn't run it on a 450. It has just as much torque and is faster than a 9257 if you ditch the voltage drop-down and run it straight at 6V. I would be willing to bet that it will be the new small tail servo of choice...

The 5084 is the twin to the 5083 that comes packaged with the Hitec5000 gyro. The difference is in the frame rates. The 5083 is specific to the Hitec gyro while the 5084 works with the standard frame rate used for most digital servo applications. They both spec. the same otherwise.

I've been flying the 5083 for almost a year on a 450 and love it! I fly it on 6V and it is VERY fast and precise.

I flew a 9257 with the Hitec5000 gyro for comparison and the 9257 never did hold the tail as perfectly as the 5083 did!

Sounds like a good choice. I would recommend getting MG servos for the swash, unless you're on a tight budget.

[cheguazam]

It's good to hear that 5084 has a good reputation, i've got 20% off from a LHS on any hitec products, so i thought of giving it a try.. jbomb, you've got me... on tight budget too..

Can i buy hs65hb and later change all the gears to metal? It's cheaper this way. Anyway the other parts of the servo is the same (pls correct me). What do you guys think?

You can certainly do that but you're only saving $30 in the initial purchase. I crashed plenty of times before my karbonite gears stripped. But... what's your time worth? And... chances are, when your crash that requires you to replace the gears occurs, you're gonna be buying other parts as well. Might as well spend the extra $30 now to not have to spend $45 later should you strip all three. It may help your hobby budget and save you some downtime.

[cheguazam]

Yup, i'll think about that, But one more thing, do i have to use a regulator for 5084 on my trex 450? I'm not really sure what does it do.

[HELINHAWAII]

No regulator needed if your ESC has one built in... most do. Which one do you plan on using? Also, should you go with the 5084MG, you won't need to do anything but hook it up and go. It's 6V capable whereas most tail servos are not.

[Andy01]

There are a few threads about this servo in the Trex 450 forum.

I have been using one for about 8 months now, and it has been good. Not into 3D yet, but for normal flying I have not had any problems. It is faster, lighter, cheaper than a 9257, and runs on 6V and has metal gears. Better value than the Futaba IMO.

Hey guys, im another that has been using the 5084 401 combo. It is one sweet tail servo. Nowadays I fly pretty hard and have not had a problem with how this tail servo holds in any maneuvers I can muster. I have been getting into alot of piro moves and the tail feels locked and consistent to me. No problems with tailslides or fast backward flight either. I have been doing all these moves with the stock align batmans and about 3000-3200 headspeed. It even holds the tail well enough to make 4 point tick tocks clean on my little trex 450. Buy it and fly it with confidence :thumbup::YeaBaby:

[cheguazam]

Bought 5084 yesterday, the LHS guy even flied a trex 250 using the same servo to convince me(even though i've paid for it, show off!) First flight this morning, spins like mad, i reverse the gyro direction, everything's fine for sport flying, hold like rock.

When on inverted hovering seems to be good BUT, when given a punch to recover (negative coz in inverted hovering) the tail would drift, lucky i quickly corrected the tail. I don't get it, before that i gave it a positive hard punch everything went smoothly suddenly when given large negative collective punch it drift (abt 40 degrees).. is it my belting? shaft? or my gyro GY401 sensitivity was too low (40% hh mode on Futaba 6EXHP)

I truly believe it is a good tail servo maybe it's just a matter of setting and matching it up, can somebody figure out what's the problem? TQ guys for your experience and advice.

[jasonFreak]

I am having the same prob, tail drift during inverted backward fly, not sure if it was my fingering or head speed not matching to the pitch, any advice fr pro? 401 gyro = 46% , headspeed = 2800 , pitch curve = 12+-

[cheguazam]

Hi jason, i have 40% on gyro, 2800 hspeed, +12 - 12 pitch curve too. Anybody please..

[cheguazam]

Oops... ignore the word curve above.

[omar212279]

I used 5084 for a few months now and all I can say it is sweeeeeeeeeeeeeeeeeeeeeetttt servo.I like it better than my previous servo which is 9257 because the 5084 has a metal gear which I like the most and as I seen on the spec. of this serco is a little bit faster than the 9257.Plus it works great in gy401 rock solid...

heliguy.com sells 3 x HS-65MG $77 (USD) shipped (6-7 business day delivery) hope it helps...

Hey guys, that is an awful lot of pitch for only 2800 headspeed. chequezem, check pm buddy. I run 11.5 pos and neg at the above posted headpeeds. Also one more thing that I did not post in the pm. Run a flat throttle curve as close to 100 percent as you can. If you cant get it, then drop your pinion size. Hope this helps guys, but I know it is a matter of getting it set up correctly, this tail servo rocks!

[Nutsinboltz27]

Just for kicks, this video was taken seven months ago by my 13 year old neice, I and my heli fly much better now due to practice and the 5084. This vid was with the Fut 9650, and even here you can see that the tail does not wag, drift or swing out on pitch punches. Anyway, your tail should perform as good or better than in this video, oh and still only 11.5 deg pitch in this vid. http://vimeo.com/1486311

[crimsonrain22]

I have one on order waiting for them to be in stock again so I can get mine. Cant wait im doing pretty good now with a hs-81 this is gonna be a huge stepup

[Nutsinboltz27]

Oh yeah for sure man :YeaBaby:

[HELINHAWAII]

You really think you can tell the difference of 11.5 vs 12 degrees of pitch at 2800? I kinda doubt it... 12 degrees at any HS is really just fine. Where you could dial back pitch is when you're running +3200 and trying to lower your peak amp draw or trying to make it a lot less touchy... which kinda defeats the purpose of running such a high HS but I digress.

[Nutsinboltz27]

Hey you could be right, but my comment on that was based on experience with this heli, those same headspeeds and pitch ranges.

[HELINHAWAII]

I too have had plenty of my own experiences with 450's... three of em. I just got rid of mine about a year ago. Not trying to be a d**k here but 11.5 is no different than 12 degrees really. Matter of fact, the last time I actually pulled out a pitch gauge was when I first setup my vbar. Eventually, you'll get to the point where you won't need one. Just fly and tune as needed. If it bogs too much when climbing, decrease the pitch travel. Likewise when setting up cyclic. Half a degree makes a miniscule of difference. If you can tell, you're a better guru than I!
