I love your site Brian! I got around to using your no-spark calculator on my e-bike. I got a HUGE spark with my 18s turnigys; now I get a lil tiny spark.
I used a tiny resistor off an old futaba tx board; I didn't expect it to work.... It worked perfectly!
I only have one question/concern
Should I have a diode wired in or disconnect my no-spark circut after I get the main leads plugged in? Someone on another forum suggested it saying my resistor would burn out if I left it plugged in.
