Ahaaaaa, nice to know its not just a function of rotation speed. We need a servo database
It'd be awesome if the fbl unit could anonymously send all settings back to a centralized server. That's the stats guy coming out in me

Hi In the tuning guide it mentions going to 0 for rudder delay when using something like Futaba BLS servos. If I'm not much mistaken, many people are using faster servos now? I could be wrong - but when I looked up the Futaba BLS stuff I got rotation speeds of the 0.38s/45deg for the BLS 256 HV @ 7.4v, whereas something like a BK7005HV is doing 0.032s/60deg - so even quicker over a longer arc. For the above I am only considering the speed of rotation w/resp to the rudder delay - not the torque output. So, don't shoot the messenger here - but could we have some more samples of speed vs rudder delay settings to guide the value we need to use? The manual has been updated - which is a great addition - with: ... (~0.04s/60°) the value is 5 ... What about a recommended setting for 0.03, 0.035, 0.045 ... just so people have a ballpark idea of how much the numbers might move. Thanks - appreciate all the help & tips. |

Hi, usually BLS servos are working little bit differently, so low delay is necessary to make it work. For other fast servos the parameter can be configured in a wider range and you can still obtain good results even with wrong values. But to make it optimal it should always correspond with your servo. Usually so fast servos will work fine with value of 0. When the servo is slower, it require more tuning so flying with too low value or too high will cause for example oscillations during a load or fast forward flight. |
