Default Blades loses track after aerobatics... Perfect while hovering

Hey guys,

I have a 50 size hirobo shuttle sceadu evolution with a gv-1 governor, carbon fiber blades, and an O.S .55 SZ engine.

While hovering in normal mode, the blades track beautifully. Furthermore, when I switch to idle up mode in a hover, everything stays perfectly aligned. However, after inverted maneuvers or very agressive flying, the blades are horribly mis-aligned. They are off-track by an inch and a half. Switching to normal mode and landing fixes the problem.

What could this be? Sorry if the answer is obvious. I'm still a bit new to helicopters.

Some background information about this helicopter. I bought it used from a 3D pilot 4 years ago. It flew perfect 2 years ago, but I stored it in my basement for 2 years and haven't touched it since.

Thanks again guys,

Try replacing the dampers in the head

The usual suspects for different tracking at different headspeeds are:

Dampers
bent spindle
loose ball links
worn ball links

Thanks guys!

Does anyone know where I could buy dampers? My local hobby store didn't have any that fit my spindle.

They're SAB Carbon Fibers. I believe they're 600 mm
