If it is a slight buzz and the servo is not getting warm, that is not abnormal with digital servos. They have very narrow deadbands and constantly try to hold position. If it is a loud buzz and the servo is getting warm, check that nothing is tight and binding.
What is "****link" means? How do I use this link? I tried all the Hitec arms I have large and small, non fits!
Turnigy is making servos that are not in the throw-away category, i.e. more than $5.00 a piece. Would it be that hard to make a bunch of different style servo arms to customers? I am not asking for free ones!
What HK censors answer?
I need the cross servo arm to mount the longer arm that came in the HK tricopter frame. Guess I have to make my own. I can get the KST servo arms for less and they are in the US. now I have to think twice before I buy the Turnigy servos!
Arrived boxed up and with full accessary set. Good length on the lead. The case is well finished and looks good. There is zero slop in the gear train and the output shaft is free form wobble. The whole servo feels solid. The servo is fast on my servo tester, and basically I cannot fault it. I will be putting this to the test on a 450 tail, I figure it would also do equally well on a cyclic set up.
All gears are metal (some looks like aluminium, some - brass, and main gear is a bit different color as other aluminium gears, probably different alloy).
So far so good, very quiet, no slop (well, compared to 3 other 20-30$ servo i have here) and very very fast. And by telling "fast" it's not only numbers (for example, prod id 14279 "on paper" has the same speed, but on tester looks like turtle compared to 306G).
I do not fly heli, so can't tell where it could fit or it could be easily stripped away (like someone told in discussions tab), but i'm going to use it in very fast wing.
Overall - very good quality, and good price. Will buy more.
So far so good. Works great on tail of an older 450 v2. Really wish it came with a round horn as well. I have read about stripping the metal splines on a crash so I notched the horn just a little hoping it breaks if I ever crash. It's quite heavy for its size - but lighter than the mini servo I was using before it by just a few grams. But for cyclic I think you would be weighing down the heli quite a bit. Might be worth it though if using a FBL setup.
