Just charged the battery up after my first drain and I wanted to try and hover in place since it's dark out. I turn the throttle up and when I get to about 80-90% (Shouldn't the heli get lift at 50-60% throttle? Seems a bit high) the heli hops in place. If I drop the throttle down, it's fine, but the moment I get it to where it wants to lift off, it hops. I've since turned it off so I don't ruin anything. I just installed symmetrical wood blades to see if they'd help and I was able to hover outside without any issue.

What's up with the hopping? I thought I balanced the blades properly...
