I'm searching for a cyclic servo alternative to HXT900. I've crashed my CoperX and my HXT900 servo gears all been broken. So I wanted to change them to metal geared ones. Do you recommend this servo? Its price is very good also. I've seen another under $5 servo Corona 929MG, but I've read some MOSFET problem in discussion section.
I need a good cheap servo like HXT900 but metal geared version. Thats all.

This servo is excelent.
Use it with 2000mm wingspan hotliner.
plenty of power and as well usable as replacement for HXT900 - at least in planes.
gear got a little play. hxt900 has none.
for a small copter the D922MG might be a better choice: faster, digital, lighter and no gear play.

Yes it's fine, only 1 of my 3 failed after two flights, tried to repair it without success.
What I can really recommend is MG14 - very fast and strong.
BTW you might want the extra gear set for HXT900 (only 1 $).

Looking for a good cyclic servo for the Blade 400. How does this compare to the Hextronic MG-14? Looks more sturdy than the HXT900. I'm looking for cyclics only at this point.

The reviews have been good on it and I have 6 on the way. I have read that they don't center the best, have some minor slop but overall good servo for cyclic and gears can be put in HXT900 but the top cap has to be changed bearing is higher. I will expound when mine arrive.

The MG90s is a faster servo than the MG90 and is quite suited for the tail. I also use them on cyclic and they perform very well on my HK450GT and same on my HK250GT.

There's a bit of deadband in these, but great gears. I'd check out the corrona ones, they are much much tighter deadband, on a par with digital performance but without the hype and current.

Just wanted to let you guys know, I installed these servos on my HK450 Pro. Mine are fast, I have zero noise and no slop. Maybe there was a bad batch that some of you guys got but I have over 50 flights and 2 nasty crashes and all the servos are holding up strong. I even went as far as buying the big brother of these for my 500 heli, the MG930's.

Tried 2 of these servos in an Electrifly EP-Su31, elevator, and rudder, works ok, but.... too much play in the gears. When you move the horn with your fingers, there is a noticeable amount of play in the geartrain.
Also, very noisy operation,again, could be the gears/motor.
Good price, appear to be digital, but I wouldn't use them in my heli because of this.
Will be changing them out of the aircraft for the HXT 900

Is the noise complaint a potential mechanical issue? or just plain noise which would be silly for obvious reasons.

Noise is "gear train" noise, possibly could use some extra lubrication on the gears.
That being said, I did leave these on the aircraft to see how they perform over time, and, so far, have been working fine. Have them on rudder/elevator, HXT 900's on the ailerons, approximatly 50-75 flights since installation, (never seem to get enough time to fly!)
As for the play in the geartrain, still wouldn't use these in a heli because of this. But, thats just personal preference.

Do these servo's fit the HK450 on the cyclic? And are these cheap alternatives for the hitec hs65mg, or are these far worse than those?

This servo appears to be the same size as the Hextronic MG-14, also sold here at HC, is known to fit in the HK450 and is favoured for use in the hk450 by many at rcgroups.
