Wild,
It acts just like a helicopter. You set it up in two modes. The first mode is Normal flight. In your radio, you mix in a certain pitch (say 30%) to stay constant. As you advance the throttle stick, it speeds up the motor just like a non VPP setup. No difference.

The second flight mode (Flight mode 2) is mixed with the throttle within the computer radio. This is activated by a switch. In flight mode 2- At mid throttle, the pitch is neutral and doesnt push air in either direction. As you advance the throttle up, the mix makes the servo add positive pitch. As you advance the down, the software mix makes the servo add negative pitch.

If you use governer mode in the ESC, the motor constantly spins at a set RPM while in Flight Mode 2. If the governer mode is not used, the motor speeds up and down depending on where the throttle stick is -100% -> off <- +100%.

Did I confuse you more? [sm=spinnyeyes.gif]
