In an Incursus with just a AB it will be near impossible to catch
MWD Kites. The only chances you have are sitting in a FW site at zero on the warp in, sitting on a bubble, or catching someone not paying attention.
If you’re having cap trouble with a AB then you should put some time into training your core capacitor skills like: Capacitor Management, Capacitor System Operation, Afterburner, Fuel Conservation, and Controlled Burst.
Get those to level 3 at least ASAP, then look into getting some to level 4 later.
