Spawning as a Player or a Vehicle

I'm looking to either spawn as a player or a flying vehicle based on the player selection GUI, I'm not having much luck with this..

TGEA 1.7.1

if (%this.playerDB $= "AirCraft")
{
%player = new WheeledFlyingVehicle() {
datablock = %this.playerDB;
client = %this;
};
}
else
{
// Create the player object
%player = new Player() {
dataBlock = %this.playerDB;
client = %this;
};
}

On selecting the Air Craft from the GUI, I spawn into the game as a camera, no shape.

Any idea on where I'm going wrong here?

Thanks
