Someone a few years ago, and ~if~ I'm remembering correctly, stated that the game "defines" the Betty as a Torpedo Bomber, and that's the issue. Being the "expert" that I am at modding, I have no clue about that. However, a couple of the mods back they took the bombs out of the Betty's equipment, and only let them carry torpedoes (or a fake one to get it to strafe)... dunno if that helps ya. Maybe it'd benefit from a cloning, renaming and re-fitting to a dive-bomber's designation (copying settings from another dive-bomber that works "correctly"), in addition to its torpedo bomber status?... I'd sure hate to put you on a wild goose chase down a rabbit hole that might be ~very~ deep, but I'm curious too... definitely beyond my current skill levels to do such yet though.
