Default esc problem

I have an old GWS TM I tried out for the first time this year. I put a fresh pack in and the prop will spin but not near the speed it needs to. when I push up the throtle it speeds up and slows down like it should just not as much umpf. I tried several batts all worked fine in other planes. does this sound like my little 2 amp gws esc is shot?

A few thoughts about non-ESC possibilities.

Are you using the stock IPS motor? Maybe it's worn out.
Perhaps you need to adjust endpoints on the transmitter.
Is the prop on backwards?

Couple of things to check:
1. Brushes in the motor may be worn.
2. 2 amp ESC is not enough for the motor. What is the motor rated at? Not familiar with motor.
3. As JDTREY said, is prop on backwards OR is motor wired backwards?? (Prop should spin counter clockwise looking at it from front)

Good luck.
