New motors and inner shaft
 

Hi. I ordered the Boomtown Hobbies Pro 180 motors and the Extended Inner Shaft when some one suggested i get new motors. I installed them fine but when i lift off, the bottom blades start spinning first and it starts spinning out of control. When i switch the motor plugs, the top one spins first, but the thrust is directed upward, pushing the heli down. Is it possible what i installed one of the motors the wrong way. Please respond ASAP. Thank you.
