Normal, it's that caps charging. When you don't see the spark then you have a problem lol. If you connect a battery in after the initial spark and it doesn't spark when you conncect re-connect the caps may still be holding their charge.

Most HV (6s+) setups come with anti-spark, the spark at that high voltage and scorch your connectors.

*If you don't like it, you can add a anti-spark resistor http://fightercatracing.com/index.ph...emart&Itemid=1
