a maximum of 45.0 volts for the propulsion circuit, measured prior to flight while the competitor is in the ready box. A tolerance of 1% will be allowed for possible inconsistencies in measurement instruments and measurement operator error for battery voltage.
A CD may waive all or some of the requirements for voltage measurement if not practical.</p>

</div>
<div>
<p class="MsoNormal" style=""><span style="font-family:"Arial",sans-serif">This has been wearing on me since the Nats last year.</span></p>
</div>
<div>
<p class="MsoNormal" style=""><span style="font-family:"Arial",sans-serif"> Let me start by saying that I market the 5S HV packs. A 10S pack is capable of charging to 43.5 volts. The rules say the legal limit is 42.99 volts. Capacity increases on the 5100 10S
in the neighborhood of 500 mAh with the added volt. That's consistent and quantifiable on my Power Lab chargers. So the added capacity is significant. In my case needed because I had a weight issue and was using the lighter 5100 packs instead of the 5800 packs
I normally like in competition.</span></p>
</div>
<div>
<p class="MsoNormal" style=""><span style="font-family:"Arial",sans-serif"> So here's the issue. At the Nats HV pack users were identified and voltage checked before each flight. Non HV pack users no check needed. The ID process was to look at the label on
the packs. So I have labels for our packs that say they are HV. I also have labels laying around that don't say HV. Albeit they say Gator Power packs instead of Power Unlimited HV. Anyone could easily dupe the system by putting a false label on an HV pack
if that's the only criteria in place.</span></p>
</div>
<div>
<p class="MsoNormal" style=""><span style="font-family:"Arial",sans-serif"> In fairness I believe all packs should get checked on the ready box. Every single fliers packs or don't check any. Or we could use an honor system which by all means I and I hope others
would adhere to thus eliminating the need to check.</span></p>
</div>
<div>
<p class="MsoNormal" style=""><span style="font-family:"Arial",sans-serif"> I hope to hear opinions on this and that it changes how it's being handled now.</span></p>
