I could be wrong, but since SPA is not an AMA Pattern event I don't think
the voltage limit would apply.

Well, let's see:  multiply volts times amps.... <VBG>

Actually, that's a really good question.  "Everyone" knows you can  
overwatt  a motor, so the motors' ratings can't be used.  But, you  
can't use more than AMA's limit of 42 volts, so you can put a DC  
clamp meter on a battery lead, to make sure a hot battery can't push  
more than about 35 amps into the ESC.

Most airplanes of that era were 7 to 7 1/2 pounds, so a limit of 1400  
watts would mean the airplanes would have 187 to 200 watts per  
pound.  That's a pretty reasonable wattage for good performance of  
those kinds of airplanes doing the maneuvers of that era.
