Mart (Graviman),
VDTR just looks like more stuff to go wrong to me. Something about keeping the design simple.
Earlier, you were understandably concerned about the complexity of the AeroVantage's transition mechanism.

At the risk of appearing promotional, what about this newer mechanism?

DESIGN: AeroVantage - Transition Mechanism - Proposed Method - 1x2 - Extendable Tubes
It extends and retracts the forward PropRotor, in a manner similar to Sikorsky's VDTR, except w/o the problem of centrifugal force.
It rotates both PropRotors in a manner similar to, but simpler than, Bell's V22.

Is it time to start a thread on Sikorsky's Variable Diameter Tilt Rotor?
