Could this be a rebadged Henge MD732. If so this is what they say about the MD732:
"Use coreless motor of high quality to develop the efficiency and life of servo Use potentiometers imported from Japan, which are of the same quality and type as Futaba servos, and the life can be 1,000,000 times.
MD732 applied to 450 and 500 helicopters locking the tail, and its function surpasses Futaba’*s S9257". There's still no max frame rate mentioned.
It look like it is. I also found the MD752 cyclic servo on Henge's site as well. Here is the full specifications from Henge's site:
"Henge MD732 digital servos have following technique characteristics:
1. Use metal gears of high intensity and accuracy, and abrasion resistance t make sure the output deviation of servo veries small after long time running*
2. Use Japanese raw material to produce outer shell, which is more sturdy and durable and can beat 120℃*temperature.

No, it's a "mini" servo. Standard servos are typically 40mm x 20mm footprint, weighing 40 - 60g. This is 30mm x 15mm and weighs 28g. Torque is equivalent to an old-style analog standard servo, e.g. Hitec HS422 or Futaba S3001.
Thanks Simon but if I'm not mistaken the torque & speed of those servos you list aren't much better and they weigh 12 gram more - for what exactly ? Are you assuming that because they weigh more they're better specs ?
Torque is measured in oz/in (or ft/lb or kg/cm) Servo specification does not change with servo arm length. Sure torque does but I am saying that these may well have the same torque with the servo arm length requiored by a HK/Trex 600 as the servos Simon lists.
40 grams was in reference to standard size servo not mini servos like these are by all means you can use this servo for trex 600 tail but it just wont be as effective as a align DS620 or DS650 and it will work harder meaning it wont last aslong. but above all else its dangerous 600 is a big machine and going for cheap servo on tail is asking for trouble trust me a DS620 is worth the extra cash
possible reason for servos getting hot are too much voltage, wrong bandwidth, wrong freqency, overloading them, or like most cheap servos dont work well with gyros.
recieved few days ago.centring is good.speed is good.im using it on my hk500 heli tail with spartan gyro.tail is rock solid,sport flying and mild 3d.servo is getting very hot after 3min,but still holding the tail,i have done 5 flights till now,lets see if it holds for long time

this servo is very, very and very very hot! at point that you cannot put you finger on it after 2 min of flight!!! I already tryed it on hk 500GT with ALIGN 3G, 3GX and ZYX FBL TAROT, all they have the same heat... it still not burned, but I think better get out it from my helis. Where have hot maybe can have FIRE!... faraway from me!!! heheheh
