I love my Hitec Eclipse 7. It does everything I need. I want to get some Digital servos. How is the centering? Is there slop in the metel gears? Thanks much for the info.

I believe the old revs cost me a H9 Edge last summer... but I hear the newer ones are really great... especially the 5945. I may try them again some day.

I have them (5945's & 5645's) in a 30% and 34% Edge540. Over 400 flights on them total - not a problem at all. They center great, the gears are tight & built tough and the best thing about them is they are programmable!!!! you can adjust the deadband, direction, speed, fail-safe points, end-points, neutral points, turn the fail-safe on or off, and use it to test other brand servos!!!
The best digital servo on the market - The 5945's bar none!!!!!!!!!!!!
Just my humble opinion!

I'm using the Hitec 5945 servos in a H9 1/3rd Cap. About 15 flights, so far so good.

How has the current draw been with the digital servos? I've read that they really suck the juice compared to the analog servos but I was curious what the real-life experience has been.

What size pack are you putting in your planes btw?

Just to clarify, you a referring to the Programmer in the above statement. It's a real nifty tool_bob

Hi Bob,
Yes I was referring to the HiTec digital programmer. A little pricey - but a great tool. I could'nt live without one - wellllll I guess I could, but It makes life a lot easier!!
Take care!!

What transmitter are you using? Have you tried the frame rate test yet? I did one test with my 9ZAPS and one with my 10X and got drastically different results. The Futaba was in the normal range of between 900 ~ 2100us with 1500 at center, while the JR was 1100 ~ 1900us with 1500 at center. There may be an explanation for this but I don't have it yet. I asked Mike in the HiTech forum. Let's see what he comes up with. Take care_bob

Bob, was the Futaba that you tested set for servo travel at 100% or for a higher travel? JR servo travel at the default 100% generates a servo timing of 1.1 - 1.9ms as you found, JR allows travel to be turned all the way up to 150% which generates a timing pulse of 0.9 - 2.1ms as per the Futaba that you measured.

Harry, You da man!
Both thransmitters were un-altered as far as throw %s. That's got to be it. Sounds like the Futaba has a chance of overdriving the servo, no?

I've got 2 5925's on elevator in a 28% Ultimate - 25 or 30 flights so far and no problems. very precise centering......

I'm putting 5925's + 5945's in a H9 Cap 33%. the programmer makes dual aileron servo setup a snap!!

Please explain something to me. I have a computer transmitter. In that, using a channel per servo, I set up every servo independently for travel, direction, centre, speed in each direction, etc., the computer handles differential, and so on. Any servos that have the same total travel but get ahead and behind their companion during that travel are taken care of by multi-point curves. The radio handles the programmable failsafe. Why do you want programmable servos?

So little time. I suspect you'll get many observations on this one. Although I'm not an expert, here goes. The programmable fail safe will benefit those users of FM/PPM where failsafe is not an option. This is a super feature to have on at least the throttle function. The programming will benefit those who unlike your example use more than one servo per surface. My 40% 3W 330 has 3 8411's on the rudder. They are ganged in line and close together. It's optimal to get each servo's deadband at neutral and matched throws at the extremes as close to each other as possible to eliminate the "buzzing" that translates into current draw and flying time so to speak. I had to use the JR matchbox to give me idle current draw at neutral and zero draw at the extremes. At $65 dollars or so each for the matchbox, the programmable HiTechs shine. The 5945's go for $79 dollars each as opposed to around $115 for the 8411's. I like the 8411 servo and I like the matchbox too. This is just another example of technology marching on. I now have a programmer and a couple of 5945's on the bench and am doing a little experimenting. Take care_bob

(like bob_nj said.)

i like the programmable servos because I'm putting 2 servos per aileron and those are then "whyed" into one channel on the RX. programming keeps them from fighting.....

Everyone seems to be having better luck with 5945's than me. I just purchased 3 of them for an AW edge and after 15 flights, there is noticable slop in the gears. I won't fly the plane again until I replace them. These were my first hitec servos and 200 bucks later they will be my last.

I have 5 5625 s in my DP 330l /went to the faster ones ///because now there rated @130 oz torque @6 volts /
Great servos as to date very little slop has developed /maybe 1 degree // 10 flights in ! I think theads have pointed out a little slop is exspected with metal gears !

If you believe your 5945's have undesirable slop by all means return them to Hitec for a warranty repair.

Do you have other servos such as JR-8411's to make a base comparison of slop in the gear train. You'll find that all metal gear servos exhibit a slight amount of wear after they have had sufficient time to break-in so to speak. The Hitec's have exhibited the least amount of wear for me and I have numerous GS models and examples to base an educated opinion with. The 8411's for example have jumped around some better than other's. Hitec uses a proprietary composite/metal mixed alloy for the gears, thus far I've had no failures and no problems with them. Other manufacturer's servo's have exhibited excessive slop in short order for me.

I don't really know if the slop is enough to be undesirable. These are the first metal gear servos that I've had. All the Futaba servos that I've owned (a bunch of 9202's in helicopters) have nylon gears I believe and I've never noticed any play in them. The only digitals that I have are 9253's and I'm sure those have nylon gears.

If a little play is to be expected, I'll keep running them. The performance is great.

Tried a couple in my pattern ship on ailerons and had to take them back out after a few flights. Centering and power are great but deadband/resolution really sucks, much worse than the JR 531's I was running. The Hitec's made the plane fly "glitchy" and was very unsatisfactory. Expensive mistake.

By any chance do you know what the deadband was? I just bought the programmer and two 5945's to play with on the bench. According to the programmer, stock from the factory the deadband on both of them was 2us. Sorry to hear yours weren't so hot. Maybe they need to be reprogrammed? Were they new when you got them?

CurtD which Hitec digitals did you buy?

My Feedback: (12)

I have 5625s and 5645 on my airwild edge 540T and I haven't had any problems. one of my friends almost crashed his quicky ,because of them. I have come to the conclusion that the servos aren't factory programed for the full amont of travel so his locked in place and the solusion is to spend money on the programer.
but I would buy them again.

If I'm not mistaken, HiTech will program them for you. It sounds a bit cumbersome, but it'll save your plane it may be worth your while_bob

Actually, the capabilities for both the 5625s and 5645s have not changed since the beginning. Hitec's ability to test them has improved and thus they were able to upgrade their specifications. I do find it strange that the 5625 can go from 77 ozs torgue to 109ozs -- wonder how Hitec tested them originally.
