Spirit System

Hi Guy's
I realize you Spirit guys are busy but i have a suggestion.

I have 3 Spirit System and had my first around 5 months ago, generally im impressed with the system but im struggling to resolve one or two issues.

When i look at the flight logs I’m constantly seeing:-
1) Rudder limit reached
2) Cyclic ring activated
3) Main loop hang occurred

I have been flying for around 5 years and have used BeastX/Brain/vBar and now Spirit, i changed to spirit because i love the full bail out feature, although i have limit knowledge i did manage to setup all the above with no real issues however i just cannot resolve the above issues with the spirit.

I have tried and tried to resolve these but with no real luck, the Spirit manual is very good on setup up of the unit and describing what these faults are, however there is no real guide which tells me how to resolve these issues.

My suggestion is , would it be possible for someone to write a guide on how issue like these may be resolved.

First from all, you have to check, when these events are occuring.

For example if you are getting these events when the helicopter is on the ground, then there is everything correct.

Rudder limit is reached when the servo horn is at the full configured deviation. It will happen if you move with your rudder stick on the ground or you will move with your helicopter by hand.

But if it is there during a flight, then there is a problem. Your rudder is not working perfectly in some cases - you have to increase RPM or tail efficiency (longer tail blades) or rudder limits. If this event is happening too frequently, your tail can even blow out, because there is no room for necessary correction.

Cyclic Ring activation is not so important and is quite normal during 3D manouvers. By increasing Aileron / Elevator limits it should be resolved.

Main loop hang should not happen normally, can be fixed by adding some filtration capacitor, ferrite ring. Also can be result of too high static discharges. Also possibly caused by very high Aileron/Elevator range.
With new FW version checking for this event should be more benevolent.
