how to keep swash-plate level during collective changes.?

[Relisys190]

So flying today When i am right-side up and hit up collective the heli climbs perfectly strait and flat.

When i am INVERTED and do a slow climb-out the heli wanders on the elevator axis.

So the swash plate is not staying level during negative collective input. What needs to be changed?

Thanks alot.

When you hover upside down does the tail climb or fall? If it does, the heli probably isn't balanced. If the tail falls, it's tail heavy. If the tail climbs, it's nose heavy.

I may not have been clear.

Even on the bench, when I give negitive collective input I can see my swashplate tilting just a few mm but it goes flat again at the max negative collective input

What settings In the radio need to be adjusted to ensure a flat swashplate during collective movement?

My heli has a great Center of gravity with the battery and canopy installed holding by the blades tilting sideways it stays out.

Thanks for the help.

Is there any slop in your servos or linkages? Are your servos at exactly 90* at mid stick?

A higher-end transmitter might allow you to adjust your servo travel at more than the endpoints, but I'm not real sure. If you don't use max-collective all that much, you could adjust your elevator endpoint so that the swash stays more level in the middle of its travel.
