sorry STLPilot but it is not like an inverted helicopter. a heli has cyclic control on the blades and therefore can push more one side of the 'prop' than the other to maintain a balance. the vpp only has pitch control and no cyclic. i think the model would need to be balanced as good as perfectly on the rotational axis of the prop, sort of like treating the airframe as a prop on a prop balancer with the prop shaft as the pivot. on that note, it may be possible to put a 3 servo ccpm setup on the front of a shocky and do away with the elevator and rudder servo's at the back end, or maybe use some mechanical mixing at the rear from the 3 ccpm servo's to control the rudder and elevator for extra control over the cyclic prop.
