HV-Servo zum unschlagbaren Preis! Bei mir laufen sie als Klappenservos in einer 4m ASW-22. Uneingeschränkt empfehlenswert.The servos seem to work as advertised but treat them gently as they are let down by the brittle plastic the case is made from.I´m using 4 of them in a glider 3,2m wingspan on ailerons and flaps. Still working great and powerfull on 6V after many flights. HK, please restock in the EU !Bought 2 of these servos. Both have a wrong thread size of the screw for the horns. No matter how hard I tried the screw went in just a little into the servo shaft and it gets stuck. The horn still moves up and down. Crappy design...I bought 3 of these to use as throttle servos on my nitro helis (using G-Force adapter plates). On the servo tester they work well, smooth and good centering. In the heli, they jitter terribly. They won't play nice with any other servo. They create a huge amount of electrical noise and make the other servos in the heli jitter as well! (Mix of savox/Hitec HV servos running on unregulated 2s lipo). Maybe they'd be ok if you didn't mix them with other servos. And the cases are still made of the same old super-brittle plastic.Best servo yet. I've been using this as my go to servo from slopers to standard class sailplanes for a few years now. Most recently as the servos in all my 2M and 2.5M sailplanes pure and motor on AERF. They are powerful and work awesomely. They are also being used in a current 3M project... they are that reliable. Operating 4.8V to 7.4V(2C LiPo). Yep, I like 'em^)Having seen that these can be used on 2s lipo directly, eliminating a SBEC/UBEC, while using a HV (FrSky 8ch) Rx I bought some to try. They work but seem quite "jerky" on 2s lipo and my Taranis 9D Tx. They work smoothly with a 4pack nimh and servo tester (though presumably with less power) so it'll be interesting to see what happens in a model. Think I'll start with something I don't care too much about.... I can always go back to using nimh or UBEC.Para el precio que tiene muy buena calidadSuper god og billig servo. Momsen skal ned i DK foer vi gaar konkursGreat servo. very well packaged no shipping damage. strong and reliable from what I have been able to see. Nice neat package.
