Using a Brain Micro in my Blade 180 CFX. Anyone else with this combination? All seemed to be going ok, but after a crash repair I cannot get the machine to stop shaking. It is not a tail wag, it appears to be an elevator (pitch axis) oscillation. I have experimented with gain settings in the Banks, going as low as 15 from as high as 28. No joy there. I have inspected and tested everything on it that rotates by balancing blades, main gear, main shaft, feather spindle, tail drive, etc. Making me crazy for sure. Any help will be appreciated other that telling me to buy some other type of heli.

You missed something that was bent in the crash.
I gave up trying to inspect and reuse parts after a crash - it never seems to work out. Especially on small heli with high headspeeds.

Parts are so cheap, just buy some new parts and get back to flying
Main mast, feathering shaft, swash - etc.

You are correct. I had two broken servo case flanges which under stress were probably the issue. I will know when I get it back together with many other parts.
