I really like this servos. It's worth of money!
But I am warrying about the temperature of this servos.
I am using 450 pro FBL with Beast X and after some 3D, cyclic servos very hot, so can't touch with my finger for some time. I bare touch the servos about 2~3secs cant'st stand the heat may burn my finger.
But it still works great.

Is it normal? what's the highest temp. DS95 can stand?

I have DS95's on my 450 Pro. They work great and are only warm after a flight. I use the HeliCommand HC3-Xtreme FBL system.

If your gain is too high you can get hot servos. Also make sure nothing is binding. Make sure you are using the correct voltage.

Thank you for comment.
What Gain do you mean? I use 6V 10A seperate BEC.

The gain on the cyclic. It's what controls how much hold there is. Same as a tail servo gain but for the cyclic in a fbl system. Not familiar with the beast so I don't know how you adjust it on one but there will be an adjustment for it. Try lowering it a little just not so much that it starts to feel mushy and not locked in.
If your servos are rated for 6v you should be fine there.

I use the DS95's on two of my my FBL pro's, had to turn pot 1 down a tad on the beast x since I was getting an oscillation with the factory setting. MY servos come down barely warm after 4 minutes of hard 3D.

My electronics if it helps:
Beast x
MKS DS95's
scorpion -6
CC ICE 50
9257 tail

Your setup is almost same as mine except I use DS95i for tail.
Anyway, Do you use 6vBEC?
And exactly how much do i have to turn pot 1 down?

I have been using these servos on two Mini-protos one is flybarless with a Mini-Vbar and the other one is stock flybared both work very will and I have never had any heat or warming up problem.

on one heli I am using the stock align ESC that comes with the 450 pro, the other pro I am using a CC ICE 50. Thats it, no external BEC. I just flew both of them and the 95's never even got warm.

I have some ds 95s on the cyclic of my 450 pro and I have one on the tail as well. The one on the tail does get kinda hot at up to 130F. I also have a 95i on the tail of a 250 and it gets warm at about 115F. Mine work great and have no bad tendencies so I am just ignoring it for now. I used to fly three or four packs in a row but I cut that down to two at a time then cool down. I temp probe everyting on my heli when I do this to make sure nothing gets hot and I haven't had any problems yet. The ds95 and ds95i both have HUGE motors for this size of servo so that has to be why they get so hot. Plus with a computer algorithm controlling them they do work pretty hard. I have had mine for about six months and use the crap out of them and I love em. They have been extremely reliable and consistent. Oh yea, I use Kontronik ESCs so I don't have to worry about a BEC.

I believe FBL with hard 3D will heat these cyclic servos no matter how you setup precisely.
I inquired MKS-Servo for this they say it might reach to 80°C and coreless motor to 100°C.

You know it's a metal case so outer surface is cool when you touch short time. But you touch it and hold 5~10secs then you can feel the real 'heat' I can't 100% for sure what says 'never even got warm' with same setup again '450pro FBL with after hard 3D'
