Spirit System

Hi,

i have a newly built Goblin Fireball 280 Havok with all stock components, except YGE ESC.
Problem is a very strong tail shaking, right after liftoff which is getting more and more till the whole Heli is shaking.
- Tail is running smoothly, checked that 3 times
- Tried with SpiritRS and new bought Spirit GTR, settings are "Goblin 280" from the Spirit First setup wizard. I also tried with rudder delay at 0 (https://www.spirit-system.com/phpBB3/vi ... all#p25120) but nothing changes.

Anybody a tip?

Thanks
Tino

Hello,
I think you should reduce your headgain (cyclic) about 5 points - I had the same problem and at first I thought its a tail problem but it wasn't -
If you look exactly you would see a shaking in elevator and ail axis and therefore reduce headgain -

Hi Mattes,
tried this today, the shaking is better, but I have a continuously tail wag (left and right), which is getting better the higher the RPM.
I also went through the whole Spirit Tuning Guide, but nothing seems to makes it better.

Thanks

Hi Tino,
my tailgain is not very high, I can say it only on spektrum stettings -
In Normal Mode: 47 %
In Stunt 1: 42 %
In Stunt 2: 40 %

I can not say rpms but percentige in the radio (Spektrum)

Normal Mode: 60%
In Stunt 1: 68 %
In Stunt 2: 75 %

Its not very high rpm, I know, but for my flying style good enough -

I hope this will help you -

Best regards
Matthias

Hi Matthias,

thanks for your settings, could you eventually share your spirit settings? Saved 4ds File?

Would be great.

Hi Tino,

here you get my settings from the Goblin Fireball -

I hope that will work for you -

Best regards
Matthias

Thank you very much

first I should ask you to excuse me for jumping in you thread with a additional question..

Hi Mattes61,

How did you configure in Spektrum the tail gain so they change when you go from normal to stunt 1 and 2 ?

Hi Pking,
this is very simple - If you choose in FM-Gyro an switch named flightmode.

In systemsetup you have an flight mode setup then you can define an dedicaded switch 1 only, in my case "switch A" and for the Hold Mode "switch H" -

In the Flight Mode Setup you have now a defined switch for flight modes and for Hold - Check here whether the switching states change as expected, if this is not the case, then the checkbox must be set to "1" -

Have you done that you can go back to Gyro - In Gyro you an set now for each flight mode an appropriate value.

You can also use the flight mode for an different pitch curve, expo or rotational speed (in %, for example 65, 75, 82)

I hope this will hepl you !

Best Regards
Matthias

No matter the FBL used the Fireball requires reasonably low tail gain. With a Spektrum TX I'd start at 30.
