Of course, by `LiPo compatible' you mean that either 1) the cutoff voltage is configurable, or 2) it's default is appropriate for whatever number of LiPo cells you're using.
Most ESCs that aren't adjustable cut off around 5-6 volts. For a two cell LiPo pack, they'll usually work as is. Yes, 5 volts works out to
2.5 volts per cell, which is too low, but if the battery is under load the voltage will drop a bit anyways.
In any event, you don't really _need_ an ESC that knows when to cut off. Instead, it should be quite obvious to you when the batteries are running out of juice -- the power will go way down first.
As long as you're paying attention and actually land the plane when you notice that the power is going down, you'll not have any problems. The only possible exception that I see is a motorized glider where you may fly it far out and a loss of power may not be very noticable.
