Maybe I'm being picky but I'm seeing something I can't put my finger on, and maybe its just the servos. When the bird is in hover and I input a small aileron command just to watch the reaction, when I stop the command and the bird stops, its like the body has a tiny wobble for a second, the head is crisp and true. Almost like the body/frame wobbles separatley from the head. Is it the Futaba 3151? Should I change that out to a 9252? Everything is tight and she spins true. Any input would be appreciated. I do not see this on my evo 90.

Check the bolts that hold the plastic head yoke on
They come loose and cause this

Then put her on the bench, very slowly move the alieron around the center - you may find a spot where the servo quivers from side to side - that's a dirty pot in the servo

I've seen the same plastic yoke getting loose syndrome.

Isolved it w/ the metal yoke

Should have mentioned that she has a metal head. I will check the servo center. Acts almost like the frame/body is a pendulum slighty. All bolts are tight. 3151 sufficient?

Fractured seesaw is the problem! Damn near impossible to see. ANd now I see there is an entire post on the seesaw. You have to look real close where the seesaw goes around the shaft for the fracture. Ordered a metal one.

frankly, I'd rather replace the $7 plastic one several times
before $70+ for the metal one that bends in a crash.

Wobble

I personally would check the head speed. A low head speed will cause a wobble. Also I would check your ball links for slop or being too tight. Check the servo itself on the bench, run it through its travel to see if it has unusually noisy spots in its travel. Tom

I made a mistake once, but I was wrong?
