FBL. My first experience

I have had to reduce Aileron and Elevator gain from the standard 12 o'clock setting to about 10 o'clock (or just under) to try and eliminate elevator bobbling (nodding).

As a matter of interest why would you reduce the Aileron gain to stop the elevator nodding.

Not being picky just asking the question.

Good question
I was working on the principle of keeping the cyclic gains roughly equal. It's probably wrong, and once I eliminate the elevator bobble, I'll try individual tweaking to see how it goes from there

don't worry about different elevator / aileron gains (I know this from the Skookum controller). The moments of inertia are different along the two axes, and this justifies individual tweaking.

Notwithstanding the fact that there are three separate gyro sensors in the unit and each one will utilise its own gain values (possibly) different to the others.


Yeah, I dunno why I did it either, and told myself the exact same thing at the field when doing it... I still did it though

LOL
