This is looking very good. Did you take any hints from the chimera, by chance?
Also, how do you handle hover/flight cg's?

This has been discussed in great detail in several other threads lately, including the thread for the OpenAero-VTOL flight controller.

David,
For best success choose motors that have max thrust that match or exceed the all up weight of the aircraft. Anything less you will experience unstable recovery modes at large angles from horizontal.

Poporbit, I thought 2:1 thrust:weight was the operating value for VTOL ??
