The new JR DS8711 may change all this.

Thanks to all who have responded here. My new project, the AM 30% Extra 260, is getting 5955TG's all round. Should be here today.

This will make my "fleet" all 8611A's or 5955TG's, so I should be able to gather some good side-by-side data over time. 30% Yak - 8611A's, 30% Extra - 5955TG's.... should be interesting to observe.

Local friend has a programmer, so I'll be learning about that, also.

As far as "bench testing".... the 5955TG and 8611A seem pretty well competition for each other. Wish I'd known how rotten the stock 8411's would be on gassers before I tried 'em. Oh well.

I'll throw in another vote for the 5955's. I've tried many Futaba and Hitec servos and they all seem to get sloppy which cause some to bounce/jitter at center. I tried one 5955 on the giant rudder on my Vision and it's solid after 50+flights. NO slop NO jittering. Full throttle 3D snaps all day long and no slop!

You can get them for under $100 on sale. I've only tried one but if they are all this good, why buy anything else

I installed my first 5955TG on my GP Ultimate Rudder last night. Very easy to see differences in gear train play between it and the 8611A's on elevators. Power off, the elevators have slop at center in the gear train that I can see and feel. The Rudder, at this point, does NOT. Very solid, feels almost like a really good nylon gear train would.

Interesting to actually "feel the Difference" and see it firsthand. Surprising, actually.

We'll see how it holds up under "flight stress".

How do you find the resolution of the 5995 compared to the 8611? Just curious as I love the resolution of the 8611 but had some lock on the rudder on a 40%er. I am now seriously looking at the 5995.

Thanks
Alan

It seems to be very SLIGHTLY less resolution AT THE SERVO. I compared "beeps" of trim from the TX before observing movement of the arm. I use a JR 10X, Trim Rate set at "4", so it is pretty fine changes. On the 8611's...."one beep", could see movement. On the 5955, "two beeps".

This is a pretty subjective and unscientific measure, but it's a good relative comparison between them on the same surface, same AC, same pushrod, etc.

I'm not really sure if this comparison is even valid and meaningful, but it was the easiest comparison I could think of to get SOME sense of resolution differences.

Thanks Bob

As i say, the benchmark now is the 8711 for JR. I havent seen one yet so have no clue but apparently gears and power are improved.

JR 8711 can't be purchased, so it's a moot point to me.

I hope when it gets released for sale that it has a better gear train.
To fly "tight", NOW, however, I think the 5955's are the right way to go for me.

On my CAP with 500+ plus flights, I flew with Hitec 5945 on elevator and rudder and JR 8411 on ailerons.
Over the life of the plane, I have replaced the gears in the 5945 twice. On the 8411 5 times.
My experience is that 8411's last about 100 ten minute flights and 5945's last about 200 or so.

We need gears made of unobtainium. I would hate replacing gears that often.

Don't be silly -- unobtainium is way too heavy.

Impervium is the best gear material but it's very expensive. I've also got some after-market nobendium pushrods in my 33% Extra. They're great!

Good one, RVM and Xjet.... true, so true.

After borrowing a programmer, and just now finishing the basic elevator setups on my new 30%'er with 5955's.... I gotta say - this is a WAY, TRULY, WAY-COOL way to setup our stuff. I wish I'd really "known" a couple airplanes back.

But the important thing is that I now KNOW the "Hitec Digital Advantage" and will enjoy it..... thanks for all the reinforcement of my decision, guys. THis is an important turning point in airplane setups, no kidding.

Nasa Space Agency (NSA) - Houston, Tx

FOR IMMEDIATE RELEASE

NSA metal engineers at the metalugy labs in Houston, Texas has announced a sucessful union
of two diconium metals through a new technology called "Interfion Reflex Unionology (IRU). The resultant
metal has now become the hardest metal know to man, at a hardness exceeding that of diamond by a factory of 2.5. This new metal has been name "Interexon" and future uses include space vehicles, ships, and ballistics. Mr. Alex Gordon, NSA project engineer says, "This metal will bring us into a new era of construction abilities, even thinking far ahead of a "starship spaceship" capable of withstanding extreme
velocity contact with hard rock type objects".

OK...I'm thinking this is what we want for our servo's, no slop, no crash damage..lifetime warranty.
haha
bobzilla

Crash? Excuse me, this is a concept I"m not familiar with.


I wish :-)

Yeah.... if we use slop-less servos, it removes another "cause" of blame for aircraft misadventures. Perhaps we should retain a few failure points so we can continue to have places to point to at post mortem.

HitechRCD, S. Korea, today annoucned 2 new RC servos.
The servo's use the newest "Interexon" metal recently discovered by NSA. The servo's appropriately named

InterexonEmensious 777 and InterexonMillinium 3000 carry a lifetime warranty..or forever at it appears these
servos are completely indistructable. Price is relatively steep at $1500USD each, but company spokesperson, Hoi Cho,
says, "We expect to sell only a set of these servo's to each RC flyer, and most likely will never see that customer again."

FUTABA spokesperson, Mary Jane, a competitor of Hitech, says they have already embollished the INTEREXON technology in their present 14MZ Radio..a reason for it's extremely high price of $3199.



wow..I did not know that!

(Only $29,550 to spend on RC before I declare bankrupcy!)

if NASA have been working on it just add a few more naughts to that price tag!

Since this topic is abt the 5955 does anyone use the programmer and what values do ull set the deadband , and speed functions . what ive noticed (since i use the hitec programmer) is that the default values are not similar in diffrent servos. so anyone just using them straight away without reseting the values as desired may have the servo not operating to its max potential and evenly.I must add that the programmer gives a new dimention in accuracy , and flexibility .

Yoga, I know lots of guys that do not have a programmer and use them right out of the box.
They are just like any other servo at that point.
Someone else can reply on the benefits of the deadband etc.

My question to all the tinkerers out there.
How many of you have rotated the gears to get a little more mileage out of them?

What would happen if I ground off the little "ninny" on the output gear and rotated that too?

Thanks_bob

Heres the catch when hitec sells u advanced programmable servos , they want u to buy their programmer . thats why they have built in a whole range of flexible options . the dead band allows one to change the width of the neutral point , to avoid servos fighting one another when two or more are used on one surface. when u have a wider deadband u can actually move the servo arm abt 1mm each side ( no not slop but it moves like a damper kinda effect) it moves upto a point before it starts humming and the motor takes over to counter the torque. when u have the tightest deadband width , the moment u try to move the servo arm at neutral , the motor takes over and produces counter torque , ull kno cause it starts humming. its an amazing feature that enables u to finetune multiple servos on one surface, even if one servo is used per control surface and the deadbands r not evenly matched u wont have tru presice control . and no matter what hitec tells u its very hard to find two 5955 with similar default values , I kno cause i just finished programing 14 of them in a 3.3m yak.

the 5425mg are awesome servos too and the torque is insane..
