AutoStab Problems
In the GOV & STAB section of advanced setup the 'Aileron Angle For Hover' slider doesnt seem to move the ailerons very much, if not atall. (this is when Autostab box is ticked).
And yet 'Elevator Angle For Hover' works perfectly and adjusts the elevator as expected. This has been the only problem I've had with The Brain. I did a test flight today and everything seems great-APART from this AutoStab feature. The aileron always wants to tilt Left when switched in and doesn't seem to work correctly in flight-( impossible to hold a hover) I really need some feedback on this as it is half the reason for buying this particular FBL unit. The setup software is v1.0.002 Has anyone else had the same problem? Feedback from MSH wecomed!! Last edited by Jamesb463; 08-13-2012 at 02:33 AM.. |

Has anyone else had problems with AutoStab?
Especially the 'Aileron Angle For Hover' slider in the advanced GOV & STAB section. Please respond! |

How far off is your bank when in autostab? Mine worked fine, drift a little bit but I can still control the heli.

Please check that both Aileron & Elevator Hover Adjust sliders work.
My Elevator adjust gives good pos & Neg Elevator movement, but not the Ailron slider-It hardly moves the Aileron. I think there's a problem with the software relating to the Aileron Slider. |

Just retested on 5 different units, they all work fine on both ail and elev slider.
What are the numbers at wich the set level positions the sliders in the advanced? Corrado

Heli is on Level surface.
After using SetLevel the Aileron slider is at -20 and the Elevator slider is at Zero The swash is tilted hard left. Orientation is Left Side, Sat plugs Up,wires Back |

Could you please post a pic of how the unit sits on the heli?, it sounds like it is not parallel to the main shaft aileron wise.

pics as requested.
swash tilted left and slider wont adjust it. elevator slider is ok. orientation seems ok I even tilted the heli to 45 deg and setlevel. slider went to -13 but slider still doesnt adjust aileron. Its the aileron slider-the unit doesnt accept commands like the elevator slider. When I SetLevel the aileron slider is at -20, Elevator slider is at zero. (swash levels if I untick Autostab) Could it be the unit- as you can see its not tilted 20degs on the fuselage! Last edited by Jamesb463; 08-11-2012 at 06:18 AM.. |

The problem here is that the software or unit thinks its at -20 when in fact its level.
The second problem is that the slider wont adjust the aileron anyway. The unit doesnt accept commands. Tx aileron works fine and as I have posted before I flew it yesterday and was excellent without Autostab so it cant be my setup. |

Can you please try reselecting the orientation?

Done that!
ITS THE SLIDER not being able to move the Aileron as the Elevator slider does. Everything is perpendicular so wheres it getting -20? It always goes to -20 when I setlevel. |

If I lay the heli on its left side and setlevel the slider shows +20 but moving the slider still has no effect on the aileron.
Could it be a faulty accelerometer in the unit. Maybe that is the cause? It flies great without Autostab. |

Yes a faulty accelerometer could be the reason, please contact your dealer and ask for a substitution.

Have contacted dealer and am returning this brain for another one.
I never thought I'd need a brain transplant but there we go. Life is full of surprises! I hope it arrives quicky and that it is OK. Many thanks for your help over this. |

Good info. We really need a "live view" showing gyro and accel outputs so we can check each axis.

Yes indeed!. I was hesitant to go on about this Autostab thing but I am convinced theres a prob. at first i was doubting myself but flights are great without Autostab so its got to be something with the unit. I'm fully aware its new and we're the 'Test Pilots' but I'd rather start a thread over this and it be me at fault rather than see Helis dropping out of the sky!
I don't mind being in at the start but its too expensive to be a crash test dummy! Hope a solution is found soon. |
