Retract and accessories use only!



Seems to be a strong servo so I hope the torque lives up to its advertisement because the speed does not. I don't have the equipment for an accurate measurement but I've had other servos of the same rated speed and this thing is not even close.

I'm going to use it for a retract servo on an Airborne Models 40size P-51 EP. Should be fine for this application. Not even good for throttle.

I selected a servo HDS 9450MG for it's SIZE , it's SPEED as anounced on your website.



The problems :



Size lenght is 35mm and not 31mm : Result : It does not fit my aluminium tray and I have not room around for adjustment.



Speed is not 0.21 sec but around 0.9 sec for 45 deviation only. Too slow for my jet steering wheel.



This servo is of no need for my application

chekcing reviews, the 9450 is slower than 9452, for my heli customers, I will recommend HDS-9452 for other friends, because HDS-9452 is perfect!! I love it, about the 9450, well, maybe could be use at aircraft application.

I bought two servo in my EXTRA 260 for aileron, it's work well and precision, but I plug 6.0V battery for keep speed up, as I tried 4.8V at first time, the speed is slow, I only recommend this servo for airplane application, I just take look about the HDS-9452MG that one is very fast, but torque is not strong...

The first view of this Servo is very good, but it is not!

This servos are to slow for every normal application. It is not recommendable for elevator, aileron, rudder, gas ...

This are not digital servos !

The Gearbox is not able to handle this torque (6.3kg/cm)! At my test, it is broken by normal movement befor 5kg/cm!

-Servos sind derart langsam, dass sie fr normale Aufgaben nicht geeignet sind!

-Dies sind keine digitalen Servos!

-Die Lagerstellen der Getriebeachsen sind so schwach, dass sie ausbrechen noch bevor 6.3kg/cm erreicht sind = Servo defekt!

-Die untere Lagerstelle des Abtriebsrades bildet das Potentiometer, eine kurze Lebensdauer ist sehr wahrscheinlich.

-Gehuseschrauben vom Werk aus bereits berdreht, Laufverhalten z.T. ungleichmssig.
