hk 450 issue: (once this is resolved i will hopefully have my maiden flight with this thing)

I dont seem to be getting enough rpm's out of my motor to lift my bird off the ground. i programmed my esc with a programming card, and i did exactly wat nuttcaze (from youtube) did on his video in terms of programming. is there something on the card i need to do differently in order to get the power?, because my motor has the specs needed
