Get your minds out the gutter, I'm talking about my new DJI f450. I recently got a quadcopter after seeing one flying around in the city. I have the 450 with a 5500 mHa 11.1v battery, naza lite and a Turnigy 9x radio. Now I've watched many youtube videos to figure a lot of things out but what I can't figure out is how to get it up in the air. The propellers spin but it doesn't go up. I thought maybe I have the props on backwards so I've switched them around but still won't go up. It's almost like it is trying to go down instead. Is anyone around to help me figure this out?
