I had some trouble first too, but eventually found the sweet spot. This thing also likes to bunny hop on you if you milk it to much and land slow. Another problem it has is that mentioned earlier, you have to let it roll out before trying to turn on the ground or it will nose over. Not nice on those expensive props. [&o]. I think the wheels catch the pants and it makes it do that when turning to fast.
Now, from what I am reading your problem seems to be that you might be still to fast on your touchdown which makes the Eagle bounce and then snap because now you lost airspeed due to that landing attempt. Try to hold it a little longer, but not until it drops by itself. You have to put it down with enough speed still. Takeoff is no problem with my one at all. Just hold a littl right rudder.
Oh yeah, forgot to mention. This thing hates cross wind.
I do love mine though, and would buy another one.
