Strange: Ordered one for 450 tail.
But it makes noise when beeing plugged to my servo tester - even when there is no input.
All my further servos do not make any sound when plugged to the tester, they are absolutely silent (when there is no input).
Do not know if my TGY-306G or not.
These are digital servos with very narrow deadbands, and as such they do try very hard to hold position. Give it a good run on your tester. So long as it does not get hot and it operates as normal, it will be fine. When you fit it to your heli, set your gyro to analog and test fly. Check it is not hot. Then try it on digital and check again for heat. I did put one on a 450 to test (I use 30g servos for tails usually) set gyro to digital, gave it a hard time and it did get fairly warm. Reset to analogue and it ran a lot cooler for no appreciable performance loss.
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.
