no good for both

Yes,digital.Very good for HK450Pro tail servo.

Thanks dude!

Nevermind. Way too heavy

Of course you can, they are even fast enough and strong enough, too for a FBL system. Should be no problem.

yes, you can use this servo as rudderservo on the HK450PRO, In combo with any gyro is always a question. Only I can say is: try it!

I use std size servos in my 500 Gaui but, yes these would be just fine.

hi.. i use the same on a trex 500 with 3g my only get hand warm.. you ca test a shorter server arm.. to have less load on the server.. i think its fast enough..

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. 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."

These servo can use them in hk 500 gt for servo cyclic?

 beenfly'n 457 points

Better to use the HK-752MG. This is a tail servo and the 752 is designed for the cyclic.

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.

I AGREE!!! For some reason this information is always really hard to come by. Hopefully someone will chime in with the information.

i dont know exactly i use it with this settings and it works fine

These are 28 gram servos designed for tail on a HK500 for HK/Trex 600 id use a 40 gram servo something with similar or same specs as align DS620 or DS650

 plasticbaldy 352 points

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 ?

 beenfly'n 457 points

For the length of servo arm required for the 600, you need a servo with a lot of torque, as well as speed. A standard servo should be used for the T550 and bigger, for this reason.

 plasticbaldy 352 points

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.

 simon4557 36 points

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

I'm running mine in a 500GT rudder with a ZYX gyro and it holds fine BUT it gets very, very hot* anyone with the same problem and has a solution.

 simon4557 36 points

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.
