the movement not is continuos but is a taps. If feel the blade they have a sound. This sound first did not feel. In flight provoke dangerous vibrations. With other servants this problem it doesn't happen |

I rectify everything during setup all 3 servants they started to vibrate as if they do not find the central point. Removed the capacitor when i give pitch this happens problem the movement of the servant seems to jump https://www.youtube.com/shorts/21Aj90hXYN4 After I mounted other servants Everything is ok. In the past I burned another servant but i read that in reality did not support 8.4v and i entered one regulator tension at 7,4v and they worked until now |

It's actually not expensive to implement the servo just needs to sense the current spike and the delay in the feedback pot moving to the correct position and switch to an error condition. Even the less expensive Blue Bird servo lines are switching over to this feature. |

my first align bl815h is burn after 3 times. I for don't break the servo i on my model directly on site where i have to fly. If electronic is on i never take my model for the blades . Other people with electronic on move the model for the blades with servo on and does not break. This servo not is all model defective i think only a series is defective. If you is in this series you're screwed. 7 year not is many if you in one year flights max 10-20 times There are servo after 30 year they work. I have 2 old servo 27year and now they work. However if the problem is servo jitter with a capacitor 1000uf the problem it should disappear |

I have hundreds of flights on Align 800 series servos without issue. Are they the best servo out there......probably not. Are they the worst servo out there......doubtful. Mine have been fine. All electronics fail. One of the quickest ways to kill an Align or any servo for that matter, is to leave the blades tied back in storage position and fire up the ESC/FBL while you "set-up" or check your heli. Don't do this. Any servo will overheat in this situation and fail. Treat your servos as precious. |

Warning from Align BL815H servos (Trex 700L Dominator Top), dont trust them I have 3 of the 815 servos that have burned out. I replaced all the circuit boards in all of mine and a buddies with the 820 and 825 circuit boards, I have about 30 flights now and no problem on a 700 goblin using 8.4 volts. this is a much cheaper fix than buying new servos. |

I don't understan why Align replace the non-serial servos with serial servos.

Flying 2 sets of these, one set with numbers and one set without numbers. Many, many flights on both sets. One set on brain, one set on vbar. No problems at all with either set at any voltage up to 8.4v. I like the servos. |

| Xfreak3D | i bought a set that was on sale on LHS... after 200 flights on logo550sx still going tough.. its a one without serial number | |

| buell47 | These Servos without a Batch number itself are the Problem, not the combination with a specific FBL Controller. | |
