I just did my preflight test. Specifically the hand test. Arming the motors and raising the throttle to ruffly 35-40%. The quad reacted as expected when tilted left or right. It tried to level it's self out by increasing the power to the lowered motor.The problem is when I tilted forward or backward, little to nothing happened.Did I perhaps miss something in the setup?Thanks all.Brian.

so i guess your motors are all turning but just the front and back ones aren't reacting to the lean. I can think of two possibilities:
1. the APM doesn't know that it's pitching perhaps because a gyro is malfunctioning. You can check this by connecting via the ap mission planner and checking the flight data screen. you should see the artificial horizon move as you move the quad.
2. the pitch PID values are zero so it's not applying any change in motor speed when you lean the quad. you could check the stabilise pitch and rate pitch values in the ap mission planner's configuration screen.
