Question: "How i can connect 7.4 V motor to 11.4 Power source?"

i have battery (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...) 11.4V,
ESC (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...) and motor (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...).

But how i understand ESC is for 12 V, and motor is for 7.4. So if i use lower PWM impulses CAN i use this motors? Or i better need to buy new battery?

Just how it is possible to connect everything to working system with lowest price?

p.s. i'm making quadrocopter.

please help me :) i just want to know if i can connect in theory, before burning something :D

You may be able to use that motor with the 11v LiPos, but if it's not high quality it may burn out. My advice is to buy motors designed for 11v.

yes also using a lower voltage battery will work :)

You won't get good performance from a 7.4v battery. Better to change the motor. Most quads use 11.1v everything.
