The <span class=''squiggly'' title=''To see spelling suggestions, click this word'' word=''skyhawk'' splc=''splc'' state=''new''>skyhawk</span> is a stock trainer plane. I have already replace the balance charger and the <span class=''squiggly'' title=''To see spelling suggestions, click this word'' word=''11.1v'' splc=''splc'' state=''new''>11.1v</span> battery so I know the battery's are fully charge.
No this has nothing to do with "fully charge" or the charge state.
It is very likely that the batteries you are using simply cannot keep up with the demands upon it.... but we do not know for certain.
The fact that you flew it fine for a while, then had a problem also hints that the battery pack itself is at fault.
Manufacturers tend to use the smallest packs they can get away with, so it often is barely enough. Add a bit of a problem, and you'll get a bad cell which will cause what you are seeing.
Did you check the temperature of the battery packs you used after you flew the plane?
Were the batteries very warm, and/or did they get squishy or "puffy"?
You should replace the pack with a higher capacity pack of the same type and voltage.
A WATT meter will tell you what is going on definitively.
If you run the motor up with the prop installed, and the voltage drops below the battery packs rated voltage, you KNOW the batteries are to blame... if you using the original prop.
If the voltage drops, the RPM's of the motor drops, and the corresponding power you see in the plane also drops.

I have tested all three batteries and they are fine. The first three days the plane was up and away and now I have this issues. If the esc is off then how can I check that. New plane, new battery and receivers.
When I tested the receiver, the receiver red light would blink fast then go solid, the <span class=''squiggly'' title=''To see spelling suggestions, click this word'' word=''tx'' splc=''splc'' state=''new''>tx</span> light blinks red. I was told this was not good. I am missing something between the esc, reviver and <span class=''squiggly'' title=''To see spelling suggestions, click this word'' word=''tx'' splc=''splc'' state=''new''>tx</span>. When I get hold of a meter I will check the watts on the esc. . Thank you. </p>
The blinking red light means that the receiver at some point has lost the signal from the transmitter.
This can be normal if you've been disconnecting and reconnecting the battery in the plane.
The light is unlikely to be related to your problem, especially if the control surfaces are moving.
