Great torque, great centering, very smooth. The servos tend to buzz without load, but since they don't draw any current, it's not a problem. Using 2 on my Teksumo without any problem.

Out of the box they worked, but when I installed them 2 out of 2 broke on there own. I took them apart and found poor solder joints to the servo motor. Re-solder the motor brush leads and are working again. Them I read the other reviews. Very poor quality control.

Sehr gnstiges , starkes, rckstellgenaues Servo , 939 bei mir sogar im Turbinen-Jet.
Wie alle Corona's bei mir Ohne Ausfall .
Manche knurren kurz ein wenig in Nullstellung - ist aber kein Problem .
Leider sind die Corona-Servos im EU-Lager selten in Stock.
Ich kaufe deshalb immer auf Vorrat in mein eigenes Lager :-) , dann habe ich sie , wenn ich sie bentige.

I haven't had this servo in the air yet but.. the bench testing has made me very happy .
It comes in at 14.2 grams or.5 oz. or71 CT or 0.456 ozt and 219 gn also 9.13 dwt. lol all joking aside its is a little heavier than they say....
1st thing I did was mount them after a quick servo test with my tester. the worst is to run wires and install a servo that wont work. I have had them. the response is very quick and you will need to adjust your travel via your radio because they are strong and will bend a small to med push rod....
2nd thing you NEED to tighten the servo case screws. every one was loose from a half to a full turn ..
as far ad
s the size of the arms they ship very short arms with it but does come with anti vibration hardware.
WHAT ARMS FIT ...
BEATS ME .
I have a huge box of servo arms and I found nothing that worked perfect. I did have one set of long red arms I could force on. they don't give a mesurment on the arm spline so I will 485mm on the splines and 483 in the splines hope this helps .
I have them moving some massive elevons so ill let you know how they work soon
would I buy more?
So far ....hell yes for the money better than the hxt 500or 900 servos they center good but they do make noise but hey they are digital

Ich benutze Corona Metallgetriebe Digitalservos in allen Gren ( ca 50Stck.)
Es war noch kein fehlerhaftes Servo dabei , alle sind stark, stellgenau, spielarm und der Preis ist dabei sehr gnstig - sehr zu empfehlen.
