As I remember the Worlds last year, electrics were checked for voltage before each flight. Sound checks were done on every plane, every flight. There was a system for random weight checks after each flight. Draw a marble from a jar, red you got weighed other color you didn't, or something like that.<BR> <BR>

As to why the limit on voltage, that’s simply a safety issue. 40V dc is generally accepted as the threshold for non-lethal dc voltage. Your skins natural resistance will prevent enough current from going through you at that voltage to kill you (though as many have experienced, it can burn the crap out of your fingers). That said, if you had electrodes poked through the skin, it could still toast you. </SPAN></P>

<P class=ecxMsoNormal><SPAN style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">There has been talk about raising that limit to accommodate 12s batteries which FAI has done for the Heli F3C competitions. I doubt you’ll see it go above that. I’m actually surprised that the AMA hasn’t put an upper limit (or maybe they have and I’m unaware) for the same safety reason.</SPAN></P>
