Corona DS339MG Digital Metal Gear Servo 4.4kg / 0.15sec / 32g

good

Bought as "standard" servos but they are significantly smaller than proper standard servo. Check dimensions if its important. They work fine on my tester and I'm quite happy to put them in my next plan build. The arms are a bit of a loose fit on the splines. I solved that by putting a washer under the screw head.

Great park size servo for rc hobbyist. Quality seem ok and only time will tell how it holds but so far all is good.

Corona appear to have responded to the criticism re the fit of the servo arms. Now they are a good tight fit. So it's an excellent servo for the money

Yes it cheap and reliable digital metal servo but it is giving me a hard time to put the arm on the servo because the arms doesnt fit well to the servo. But overall is still good purchase from HK, I bought 4 of these for NXT Nemesis.

I just received 4 of these DS339MG from Corona and everyone of them has loose servo arms. They do not fit the spline well at all. It is way too much slop. I tried fitting some Hitec 85MG arms on them but they are too small. For now I put a small piece of electrical tape over the spline to get a more snug fit but it's still a tad sloppy.

Great little mid size servo, very powerful and accurate centre. Have yet to actually fly the plane they are in but if they are like there little bothers, should do the job well.

PAS TESTE ET PAS ENCORE MONTE;

PAS DE JEU CONSTATE LORS D'UN TEST SUR TESTEUR DE SERVO

Habe diese auch schon in anderen Modellen verwendet, sehr schnell, stark, usw....

gerne wieder.

Ne ho comprati 3 il primo funziona bene, il secondo vibra che sembra abbia l'alzaimer e il 3 mi manda in corto la ricevente
