There is no file in the Model Presets for the Goblin Fireball.
Should I use the default or maybe the Goblin 380 ?
Thanks

Yes, you can.
There is nearly no difference in the configuration.

But we will add the preset in the upcoming version :)

The Hobby Wing controller in the Fireball has an RPM output.Can I infect the Spirit or comes the speed of the Uni cable?
How can I adjust the 24 poles of the motor?

Brand new Fireball with Tail Wag can't get rid of it.
Tail gain down to 30% can I go any lower ? Any high I get fast wag in Idle Up 3
Setup files attached. Will do vibration logs later today.
Any suggestions ?
Thanks

What tail servo do you have?

Probably you will need to set Rudder Delay (decrease). Reducing Pirouette Consistency to 150 can improve it too.

It is also usual that new goblin kits needs "smoothening" of the tail mechanics since in certain angles it is not moving freely. Only then tail mechanics will perform well. Very often it is sorted by itself according the pilots after couple of flights.

Very important is that each ball joint is moving with absolutely no friction and there is no point that is causing additional slow down.

Tail gain should be around at least 50%, but it is also very dependent on the servo.

Using the stock DS12T servo.
I'll make those changes along with striping down the tail and check it smoothness.
Report back tomorrow if it improves.

For this servo I recommend to set Rudder Delay to 0.

Piro consistency set to 150, Rudder delay set to 0.
Tore down the tail assembly polished and oiled the tail shaft.
Tail gain at 50% seems better at lower head speed but at higher head speed
still getting the fast wag. Reduce the gain to get rid of fast wag but then have slow wag
at lower head speed. I don't see any vibration issues, logs attached.
Have any other suggestions ?

I have the same problem with commuting fast tail.
The tail is smooth running.
Servos are standard sab.
