  1. saves servos but random indexed 4 Star Review

    Posted by on 15th Apr 2018

    Love these servo horns. I’ve crashed my Blade 360 badly several times and each time, I break one or two of these servo horns but I have never damaged my KST servos. Before installing these horns, I would strip servo gears and even snap servo shafts. To be fair those damaged servos were Blade servos which are of considerably lower quality than the KST’s.

    My only issue is that the molded splines are not consistently indexed. I.e., if you replace any servo horns, you will need to re-level the swash especially if you also had to replace any ball links between servo and swash. Sometimes, the new horn lines up pretty good compared to the old one and if your links are OK, then just check/adjust the tracking on those damaged or new main blades and let her rip!
