| Without the mainblades on, your quoted headspeed is irrelevant. Put them on and then test it.
Here are some places to start.
At center stick, there should be 0 degrees of pitch.
At 3/4 stick, there should be around 6 degrees. This is usually what it takes to hover an eco. You should also be somewhere around 75% to 80% power in your curve.
At full stick you should have 9 to 11 degrees of pitch, as well as full throttle engagement.
Make sure you set the throttle hold switch setting to 0% and use it when you are testing your heli. This allows you to check pitch range, while not having the throttle engaged. Also useful when you are walking to runway and when you go to pick it up. Makes it so you don't accidently bump the throttle. Trust me, it is a good idea.
Make sure your transmitter is also set to allow full throttle. I had this problem and it drove me crazy. When in doubt, READ THE MANUAL!!!
The motor and pinion combination should be fine. You might check that the mesh is correct for the motor pinion to main gear and then the main gear to tail-drive pinion. This is another common area where power is lost if not set up correctly. As Rob_T stated, as you increase pitch, the motor should not "bog" down much. It will, if you give it full collective from 0 deg. pitch. If you are smooth with the throttle, you won't notice a drop in headspeed as you increase pitch. (This is true only IF your throttle curve is correct.) If it does bog throughout, your curve isn't right or you have too much pinion and need to go smaller.(Highly unlikely)
Another mistake is tail belt tension is too tight. Loosen it up a bit. Likely that could be the simple fix you were looking for.
Well there you go. A few things to check. Hope one/all works out for you. Also you should go to www.dream-models.com There is a plethora of info there about the eco8. Let us know your results. Bill
