All I can report is that mine have stood up well to many crashes on my 500, without any apparent ill effects!

I think they're unbeatable value for money on a 500.

It is too quiet about these servos. Seems the 500 class it not that popular anymore?
I never got these for my Protos500. The used frame came with Hitec HS-5245MG servos and they seem to hold up perfectly. Basically got the heli for free with the servos

Might get the 732 again to try on the hurricane425.

I just got another 3 for my Gaui X4 II. Ran them on the tester for half an hour to check them and bed in the brushes.

The case on these servos look very similar to the MKS DS9660A. I wonder if that is what they are modeled after.

My other set are still going well on the 500DFC, so that's what lead me to getting another set for the X4, that and the price.

Are the rest of the internals the same as the old ones? I had one of the old ones that was bad out of the box and never got around to replacing it. Do you think we'd be safe mixing cyclic old and new?

So would you guys suggest these HK-752MG servos for the cyclic of a T-Rex 500 DFC with a BeastX FBL controller?
I am still learning on Forza 450, so I will only be doing sport flying, no 3D or anything like that?

TIA

They are great servos for pretty much any FBL controller. Should work fine.

The T-Rex 500 will sound noisy compared with your Forza! Don't forget you can run 350 blades on the Forza, maybe with the 14t pinion, which makes it fly a bit "bigger". I like how smooth and quiet (and tough!) my Forza is so much that the only 500 I will now consider is a Protos.

I'm running TGY 930's on my 500 now. They are rated at 0.14sec/60degrees, but they feel more like 0.20sec.
Looks like the 752's are back in stock. I'm getting 3.

Im having some issues with a few.. I ordered ten of them for two different planes, two were acting odd.. jumping back and forth while moving, it's really weird.

HK 752 servo (1 min 48 sec)


I got HK to replace them, but one of the two replacements is doing the same thing. Any ideas on what the problem could be and how to solve it before I just say forget these things?

I pulled the case and gears off one then plugged it in to a rx and let the motor spin until I found center on the pot.
I then used the tx trim to slowly move the signal sent to the servo in one direction.. of course the motor starts spinning to try and move the pot to match the input signal..

after 6-7 clicks of trim in one direction, the motor would suddenly reverse direction.. I kept taking the trim further, and another 6-7 clicks the motor was spinning the same direction it started with..

To me this indicates something wrong with the digital controller's interpretation of the input PWM signal, but I could be way off.

Well I have not experienced that issue with the ones I had/have. Perhaps a bad batch that HK received or they change an IC along the lines.
