TBD's are as slow as ever (and anyone who read about them, knows just how slow they were).
However, I have noted that I cannot get a Mk 13 Torpedo on the TBD. They are on the AI aircraft, and on the TBF's, and I checked the weapons.ini for the TBD - it's there (Anti-ship). On the loadout page, it shows as being available (left side), but not available to load. Good news is that I can drop a "paratrooper"... Not sure where that came from, but I suspect it has something to do with settings somewhere.
BTW - Having a great time flying these slow, lumbering beasts - compared to the Scooters, Huns, 'Truders, Phantoms and others from YAP (but those are awesome too).
