Corona CS-239MG Slim-Wing Analog Servo 4.6kg / 0.14sec / 22g

Excellent servo for the size and price. Surprisingly similar performance to the identical digital servo. Very precise and repeatable with excellent centering. No jitter or hunting and fast and powerful when running on 6v (I haven't tried them on 4.8v yet). Great for park flyers and strong enough for larger slow planes. I will definitely be buying more servos from this manufacturer as this review is identical for the three differenet types of Corona servos (8 servos in total) I recently purchased. None of the 8 servos showed any problems whatsoever. Very consistent quality.

I bought 3 for a HK Reverb. They have a bit too much gear play for a hotliner but at this price they are a good option for a medium-large mild glider.
I got in touch with HK customer service to let them know and my problem was solved in 24 hours. 10 stars for them.

A great servo for this price. use them for flaps on a 2-stroke plane, no problems at all.

Granted these Corona servos aren't hitec. But then again you're not paying hitec prices. Haven't had any issues with the servos, running them in a composite body two-stroke powered pylon racer.

Eigentlich schönes Servo aber eines von zwei ist mir beim Setup durchgebrant.

Excelente para ser usados en las alas de los planeadores o en planeadores en General

PAS ENCORE MONTE , PAS ENCORE TESTE;

CE QUI SERAIT BIEN C'EST AUSSI DE LIVRER Turnigy Ply Servo Mount for Slim Wing Servo - TGY-S712G AVEC POUR LE MONTAGE DANS LES AILES PUISQUE SE SONT DES SERVOS D'AILES;;;

Received 4 of these sevos today. Tested on my servo tester all worked fine with good centering. There is a good selection of arms which fit tight onto to output spline with no slop. Short self tapping screws are supplied for fixing the servo onto the mounts. Excellent servo for the price will buy more.

Nice slim servo. Perfect working. I like it.

Tolles Servo und zudiesem Preis nicht zuschlagen.
