Oh, and these are forceful hops, like it's being thrown to the ground really hard. It just fluxes in place but it seems pretty rough and not normal.
Sorry to hear your having trouble. Mine doesn't list off until about 75% throttle, the blades don't even start spinning until about 25%, thats how most helis are set up.
I am not sure about the hopping, mine was kinda hopping today in the grass int he yard but i think its cause i was on unlevel ground the reason mine was but it wasn't that bad as your describing.
