hello, i am seeing these servos online quite a bit. and they are at a very reasonable price. the specs look good also (although at some sites, it seems like these were discontinued by hitec).

anyhow, are these servos any good? the price sure looks good ... will appreciate your feedback !!!

Very nice kit.
Some folks are a bit nervous about the metal gears, but the servo is very nice.

the ones i saw online were with karbonite gears, the specs on the servo sounded too good to be true ...

* Torque (oz) 4.8v/6.0v 91/109 oz
* Speed 4.8v/6.0v 0.13/ 0.10 sec
* Bearing Dual Ball Bearing
* Size HxWxL 1.5" x 0.8" x 1.5"
* Weight (oz) 1.76 oz

do you think they are suitable for heli use? or am i reading something incorrectly?

HB stands for carbonite gear with ball bearings. Only MG servos have metal gears.

I think there was some problem with the servo initially. Hitec increased the servo arm screw lenght and no more issue. You might want to search around, plank forums might also have some info on this.

I've been using three of these servos for over two years in two different helicopters. First was a Fury that crashed three times with them, never a stripped gear. Now they have been in my 3D Freya X-spec for the past year and a half.

Still no slop and center just fine.

I've been using them for 2 years or so in a 50 and a 90 - no problems, still tight and as Erich says they are quite crash proof. They were superseded for the 6xxx pretty quickly - don't know why. You don't locktite the screw which secures the horn or you'll make the output shaft brittle - which is plastic anyway, this was the cause of some failures.

I'd say that 9252's would be a better choice for ccpm at a similiar price for the extra precision - some guys complain that the hitecs don't hold as hard at centre.

The 69x5 is karbonite, the 59x5 were metal, at least last I looked.

5925MG 5945MG 5965MG 5985MG are all metal geared.

5975HB uses carbonite gear.

All 59XX are digital coreless.

thank you for all your responses. i just placed an order for 3 of them, less than 30 a piece. according to my research, they should have sold for closer to 90 bucks a piece (that's how much other shops are asking for).

i just hope these are not the same as ds821 - which are known to break. BUT their price is around 20, most of us know they are pretty cheap quality, and the main reason we have them is because they come with the dx7

cheers ... khan

something i do not understand, is ...

"The programmable digital circuit allows the user to set end and center points, deadband, speed, and more with the optional HFP-10 programmer"

this was one of the specification of the servo, does it mean that i need to program it, or is it like regular servos which are plug and play ... and program it if i want to fine tune it only?

You are correct, the programmability is why I chose them originally for a CCPM Fury. You can match endpoints, centering, and speed of all three servos perfectly. Also, if the performance changes over time, you can tune them back to where they were, rather than screw around with radio mixes.

The programmer from Hitec is about $100, but is well worth every penny as a setup tool. It not only programs Hitec servos, but can drive any brand servo, using digital PWM. You can also test receivers' PWM outputs and voltages, to trouble shoot your entire on-board system.

I use the programer/test a lot at work on UAVs.

yup, the price of the servo went back up again ($90) on eBay, i guess i got real lucky somehow.

i had asked Hitec regarding the servo, and this is what they had written back ...

That’s a good deal; I would buy them all at that price!!

Subject: Re your digital servo --- HELP

hello,

i saw the HS-5975HB on the internet for sale, only for $25. the specs on them seemed very impressive:

· Torque (oz) 4.8v/6.0v 91/109 oz
· Speed 4.8v/6.0v 0.13/ 0.10 sec
· Bearing Dual Ball Bearing
· Size HxWxL 1.5" x 0.8" x 1.5"
· Weight (oz) 1.76 oz

1. is this true? all the above mentioned, for $25 ... with Karbonite gears !!!

2. does these servos need any programming, or do you just plug it into the receiver and they start working.

look forward to hearing back from you soon ... cheers, Khan
