I tried lowering the piro consistency but it did not help with the tail gain so I brought it back to 170.

Gain is perfect now at 43 so I am just going to leave it.

Trying to fine tune the cyclic gain though, I had it at 57 but would notice drifting in tic tocs so I moved it up to 62 and now 64 and still don't notice any bobble. What is a typical head gain for a 450?

I'm up to 75 and still do not notice anything weird. Is this much too high for a 450?

Finally noticed some weird shakes at 75, moved it back to 70 and I think it is perfect there.

I can't seem to get the tail to feel as solid with the bigger tail blades. The gains had to be lowered to about 40 to get rid of tail wag but it kicks more on hard collective manuevers. Should I add some revomix?

The stock tail blades could blow out but didn't kick as much with the gains at 62 for tail gain.

Another thing I have noticed a bit is on hard pitch changes the heli will tilt toward the tail. What parameter should I use to make the pitch pumps perfectly level?

You can try to put your ball linkage closer on servo horn of your tail servo.
This should help.

You can increase pitchup compensation. Also you can play with your CG to solve this issue.
Upcoming firmware should determine dynamic geometry changes little bit better which should help in this area too.

Tomas, what happens if the piro consistency is too high?

I bumped mine to 190 just to see if it would help the tail. I can't tell if it helped or not or if it has anything to do with the tail. It felt a little better. But what is the negative part if I go too high on piro consistency?

I did notice a little weird behavior in flips and rolls

Also, I know you always say not to add precomps (revomix) but I can't get the tail kick in pitch pumps and tic tocs to go away without it. Its getting better. I have added +3 so far. I will bump it up one more and I think it will be perfect. Once I get my tools back i'll try to bring the servo horn in closer for more resolution.

Revomix really didnt help much, I went back to 0 on it and it feels just as good as with it. Going to keep it at 0.

Tomas, what happens if Piro consistency is too high?

i have mine back down to 175 and it feels great still, couldn't tell much of a difference between 160-190. Aileron rolls seemed to have more of a weird shape wth the higher numbers but that was the only thing I could tell a difference with.

Hi

High piro consistency can cause unequal stopping performance, big tail oscillations in pitch pumps and fff flight.

There is company holiday so I will respond later with more details.
