Hi Just noticed a strange behaviour of my FBL or Software. When i aktivate the pitch adjustment all three servos are moving but not equal. https://vimeo.com/772945811 What could cause this problem? Software and Firmware are 3.4.3 the newest. Thanks in advance |

Hi, Problem could be in Servo Travel Correction. Please reset the settings to defaults. Then make sure to check length of the servo arms. |

This behaviour was after the factory reset so nothing else was set up except receiver and channels and servo frequency/directions. |

Do you have the correct movement of the green sliders in the Diagnostics tab? Do you have the unit position set correctly? |

Ya everything else works fine. The only problem is this behaviour. When i move it faster the difference gets even worse. I finished the settings without using the pitch adjustments. So far everything looks good. I have an other Heli with an spirit gt wich i can test if the same problem occurs. |

Hello, how good is your powersupply ? Is it possiblewise defective ? Tanke another ESC or an good battery to rule that out - Unfortunately you can't watch the video because you have to register, please upload it again so that you can see something, then others can also help you - You could try swapping the servos (changing the wiring) does it behave differently or is it still the same? If the problem moves, is it the servo - What can also be the case is that the frequencies on the servo are set too high, set the frequencies to 60Hz or 100 Hz, for example... Regards Matthias |

Hello, I have seen your video, very interseting ! As a note in advance, one must of course say that huge values should not be adjusted here, this only serves to achieve 0° pitch in the middle position! Normally this should not mean a huge adjustment - if the adjustment is very high, then the basic setting is already wrong, such as the linkage length from the servos to the swashplate, i.e. at 0° pitch the swashplate is not in the middle... What I would test first of all, from start to finish, would be the following - disassemble the rotor head and then place a swash leveling tool on the main rotor shaft, then check the home position first, is the swashplate leveled in this position? Then check the two extreme positions (positive pitch/negative pitch) is the swashplate level there as well? The extreme positions can then be set using servo travel correction - Regards Matthias |

I do not need the pitch adjustment for my setup. I finished it allready. I used it only to lift the swashplate to fit the swashplate leveler under it. This was the moment when i noticed the behaviour. I set back everything to zero and used an universal tool from the top side. I thought this behaviour is a bit strange and can’t explain it really. |
