| Post subject: | slow pumping response |
Hi One of my heli's flip response is quite fast but when I do pitch pumping response is sluggish. blade length = 360mm (480 class) collective angle = 13 degree cyclic angle = 8 degree RPM = around 2800~3400 (?) anyway, increasing rpm didn't help flight style = 6 feel like internal expo for collective pumping... but not for cyclic movement. Which parameter should I change? |

Hi, unfortunately there is no parameter that could affect the collective other than the Collective Pitch Range. If you feel a delay, then it could be caused by a problem with axial ball bearings in the rotor head. Then it will cause delayed response and also other unwanted phenomenons. But firstly you can notice slow collective response. So I recommend to check the rotor head. |

It was my bad. Collective was 10 deg. I've changed it to 13 deg. and it feels alright. I will reduce cyclic from 8 to 6 deg. I like the rolling. it's quite smooth compare to *BAR. KH |

Great! If you mean Cyclic Ring, then even 8° could be too low. This limit should be at least around 9°. |

I meant cyclic pitch angle. I think I set it as 8 deg. during PC setup. (May be I mixed up with *BAR - I remember it was 6 deg. in *BAR) Cyclic ring is 11 deg. Anyway, it feels alright so I will leave as it is for now. Thank you for advice. Regards, KH |

What do you mean with "Cyclic pitch angle" being different to "Cyclic ring" degrees? |
