When I calculate the motor to use on a certain voltage, I like to use values that are under load. For example, with Feigao motors, I use the kv values from BK that are under a load. For Lipo, I use 3.4-3.5v/cell, and for A123 cells I use 2.8-2.9v/cell. In 1/8 conversions, I shoot for 30,000-35,000 RPM loaded, since that RPM would pretty much be the worst case scenario (there's a good chance the RPM will be higher than that).
