MKS HBL550 X5, Titanium Gear or Not? For heli only?

Can anyone shed some light on these servos:

HBL 550 X5, Brushless MKS:

the title says titanium gear, but the description say alloy gear. I have not gotten anything clear, even on MKS site, alloy gear.

Seems like overkill for helis. We typically run around 150oz on 700 class 3D helis, maybe 200+ for something like the Synergy 766 or a TRex 800.

Helis need speed more than torque.

Thanks anyone form MKS can confirm/deny these are titanium gear servos?

Also this seems like a half price version of the HBL380?

Well boo hoo , I ordered 15 from amain during the black friday sale and they appear to be lost. I hate this UPS surepost garbage, apparently UPS brings it to the post office and they do final delivery, or so they say.

Today I was waiting and refreshing tracking every 15 mins like a little fool for these servos for about 2 hours, UPS driver came, delivered a prop, no servos! I showed him the tracking and he said nope that is not our tracking number its coming from the post office!??

Fine, another hour later here comes the USPS truck, dropped of spam mail and the usual bills. Showed the tracking number. Guess what he said, NOPE that is a UPS tracking number not post office.

So now I'm going nuts trying to figure out what is going on, called ups, called usps they each blame one another finally called amain. Now they dont' know what is going on, and UPS decides to retroactively mark the item delivered by the post office.

I love how at 3:30 Pm I"m calling to find out where my package is and the tracking number shows intransit.. but at 4:00 P.M. after my calling they decide to update the tracking to say delivered at 1:30 P.M.

Long story short, Amain said they will get new servos out to me... when they get them back in stock in the mean time UPS an USPS tag team are lolling and rubbing each other's nipples and could careless

i have flown these all last season in my 60cc extra and have them in a 120cc extra along with 3 700 size helis, they are awesome for the dollar. i have not had any problems with them, both planes got a little over 200 flights this last year no gear slop and seems to be just as good as day one.

The prop came from an ebay seller, it just was delivered on the same day the servos were supposed to (the prop and servos were separate orders from separate companies). I was just annoyed to see UPS deliver my prop but no servos. still waiting on amain to get these back in stock.

Yeah this is getting out of hand, we need to design large lock boxes to stop this rising theft spree.
