Post crash Dynam E-Razor 450 hovering.

It's trimmed and flying, looks to me that it's set up enough for learning with.

In the air the blades weren't quite tracking, after the flight I increased the pitch of the orange taped blade one turn.

I'm wondering and suspect that hovering low, the ground effect is causing a "swirling hover". Also, I noticed one blade was tracking lower, so that might also be causing a "swirling" effect. Plus, I'm a beginner.

Next flight, I'll check if the blades are tracking straight and hover higher above the ground and see if it swirls less.
