I have a few questions in regards to the DA100l ignition system. They do not have a manual or talk about it at all on DA official site.
I attached two pictures.

What type of connectiondo I have to solder on?
What type of on off switch works best/recommend?
Battery recommend?
I have a spare2000mah 6v nimh not sure if fine or not. Has a standard receiver plug. The ignition system says it needs 4/6volts nicad pack which is why I ask. Do not believe it matters. I believe nicad handle better in higher drain but I do not know if this is necessary.
Good kill switch setup?

Thank you for any help..apprecaite it
