View Full Version : Those of you using HS45HB's

My house jumped right out in front of my little Gauis flight trajectory. One of the Bluebird servos is no longer with us. I had a new set of HS45HB's so I installed them. Are they supposed to chatter all the time? You would think they were binding from the sound, and this is sitting on the bench. I can bump the stick on the Tx a couple of times and they will quiet down but as soon as you move one of them it's back to chatter. Just curious if others have the same issue. I may go with programmable Spektrum servos.

mine are quiet, and have survived many crashes without issues

I have a DX7 and ar6100 I wonder why mine are so noisy?

if you plug in a rx battery, do they still breakdance? did you try rebinding? is there a cut wire on one of them, or on the esc?

Yes they breakdance w/ rx pack, Yes on the rebind, No cut wires. The bluebirds that I took out were quiet. If the bluebirds didn't have centering issues I would have been happy with them. The heli flies fine, as well as I can fly it anyway. I mean no glitching or noise type issues.

that's what I run too. I'm not sure what it could be... interference? servo wires shortened? bunched up against other electronics or something? I have mine all shortened, but it is still very close to esc, battery, gyro.... with a heli this small there just isn't much room for anything.

Try undoing the links from the servo, and just run them with no load and see if it's still doing that... that'll tell you if it's binding in the head. And maybe just try plugging in one servo, with the wires not anywhere near batt/esc. I doubt that it's rx since it flew fine before and now... sorry if that's not much help but I can't think of what else it can be.

I'm thinking maybe the receiver. These servos chattered before I shortened the wires and while they laying on the bench with no servo arms attached. I'm gonna try another receiver just for s&g's

All three cyclic servos still noisy with a brand new 6100 v1.6 Maybe they aren't broke in yet. I'll run them for awhile and see how it goes or else it's time for different servos.

that's weird. give hitech a call. maybe they can help you.:thinking

Mine do exactly the same thing, on the heli or off, since they were new. Buzz all the time; a blip on the tx sometimes stops them. Doesn't appear to harm anything. Clueless, though. DX7.

Hey Surf do the seem to get quieter after breaking them in? I suppose it's possible they have really tight clearances brand new. Mine work great, they just sound bleh. I should have gotten the spektrum programmable servos, might still.

They haven't yet. They just buzz and hum. Don't appear to be binding. Work just fine.

Servos do that to a certain degree. The receiver sends electronic pulses to the servo to sort of check the status of the servo (whether it's under load etc.) that causes a small amount of movement making that noise, but if it's excessive there might be something wrong. Your servos are probably fine. I wouldn't worry about the servos once you've exhausted all the possible problems the other people have proposed.

I think they will be ok too they work great. I am just surprised because they are Hitec. I have Hitecs in 2 other helis and they are quiet but they are HS65mg's and HS225mg's. To hear them you would think they were some el cheapos or that they were binding. I really want to try the Spektrum DS60's. I may do that, if I don't get another heli. :roll:

If all three are chattering, then it's the rx or interference.
the 45's are great, though I'll swear by my <5g Dymonds!

You might try relocating the rx, or the esc.

The (hopefully temporary) addition of a couple loops of spare wires through a ferrite ring, one lead a time, might help track it down as well.

Hope this helps..

I didn't think about the ferrite ring, I'll have to give it a try. Thanks Gr4yb3ard and what are <5g Dymonds?

What's a ferrite ring?

What's a ferrite ring?

he bought it for his lady.





that goes between the speed control, and where it plugs into the rx. it's a metal ring that helps take out interferance from the speed control. the wires loop in and out of it about 4 times. i'm sure you've seen them before.

running 2.4 ghz, dsm2(like an ar6100) interferance isn't supposed to affect it, but lots of guys run them.

I know what you mean now, I have one on my T-Rex. I just wasn't familiar with the term ferrite ring. Thanks.

Darn, I try to be brief and to the point, and end up being cryptic and not providing the info I want.... ;-)

The ferrite ring is a ring of magneto-conductive material, that when used as a magnet, tends to damp high frequency impulses. That is, it works exactly like a choke coil.

When you loop some wire around one of these, through the open hole of the "dougnut", you end up making a choke that can sometimes kill voltage spikes and electrical noise.

A lot of equipment ends up with these somewhere, but they're also useful
for diagnostics, put one in a few places in your setup and see if theres a difference. Useful to help spot interference problems.....

The "5g Dymonds" are simply the Dymond servos, not the usual crystaline carbon bribes that I find necessary to give Girlfriend to allow me to play with airplanes... ;-)

They are light, at (actually) about 4.7grams, and center well, with decent, but not notable travel times. They look cheesy as h#ll, but are durable to beat the band, and I've never stripped a gear in one. I can't remember who recomended these, but I absolutely love them.

The only problem with them and the 200 though, is that they don't nearly fill up the servo bays, so they're only supported by the mounting screws. If anything works loose, I'm puckered!!
