If you make a single build with 9 wraps Kanthal A1 with 2mm inner diameter, you would hit around 1.5ohms. That will be roughly 7 to 11 watt doing the battery drainage. This will give a heatflux around 120 mW/mm². Not sure how satisfying such heatflux would be on a above ohm build though.
Talking such thing as ohm, then maybe you would like to provide some info about what your prefer ohms is, and what heatflux is your sweet spot as well. That would make it a lot easier to suggest a good build for you.
Anyway, as Norseman is pointing out, then i am not even sure this atty would be suitable to use on a mech.
