Hi all, here`s a question for you. When I plug in my Novak Brushless GTB (with the power switch in the off position), to my orion 3200 li-po`s, it arcs when I plug in the last power wire to the battery? Is it the cap.?

YES it is the cap taking the voltage out of the battery

You should see the arc on a 5S 18.5v system - its gets people's attention, ZAP!! Will eventually eat a deans connector too. For hi voltage systems, you can add a resistor and modify the way you hook it up and basically let the cap charge thru resistor instead of that all at once connect ZAP. Its cool a few times though, especially towards dark.

Just wanted to make sure thats what it was. Thx. for the replys guys
