[NSRCA-discussion] wattmeters/whattmeters

[Ron Van Putte]

I sometimes use a Sears clamp-on meter.  More often, I use a Watts Up  
meter from BP Hobbies.  The Watts Up is inserted in the line between  
the battery pack and the ESC.  It measures volt/amps/watts, with a  
100 amp limit.  Street cost is about $50.  I only use it for ground  
testing; it does not stay in the airplane.
