Hey guys, I currently flying a hbk2. Last week I had a bad crash I broke some linkages and the starboard servo. So went to the LHS and bought the new servo(ek2-0500). After installing I found there is something wrong with it. Its speed is much lower than the old ones and its motor noise is much different with the others. so uninstalled it to find out what is the problem. The circuit board inside is far different with the old one. I just swaped the striped gear with the new one and still running the old servo.
does the e-sky have two version of it? Another difference is the part number is written on the new servo while the old ones have only the e-sky tag.
