Also, one thing that might help is that you are not anywhere near full power when you are hovering. It sounds like you are worried that you are too close to the limits of your motors or ESC's...? If so, and you don't have a wattmeter to test actual current draw, hover for a minute or two, land and immediately check the heat of the motor cans and the ESC's. If your response to grabbing a motor can or ESC is to yank away newly blistered fingertips while yelling obscenities, then you will probably want to do some shopping for other motor's or ESC's, depending on what caused the burning sensation. If, on the other hand, you can hold your fingers to them for a few seconds without blistering, you should be fine with running what you have now. Once you learn more and start doing more serious maneuvering, you'll want to perform the heat check again to be sure you are still not over-stressing anything.
