1. agree, but you do get them WAY before other nations.
2. agree.
3. get more than some.
4. agree and never load scouts as well (i saw a RFAB oyodo yesterday)
5. agree.

but it depends on how you want to end up 2FP and 6DB is ok but if you want to play in fleets and HA then you need to reverse that and have 6FP and 2 DB or better yet 8FP and 2DB so you can mix and match.

always use at least +12's

you will need a seaman with a fighter stat

then either gunners or you can use rep/rest to boost SD its up too you.

always use main guns on oyodo, use T mout to level extra.

dont use a medic at the moment you dont need one.

just for your info i have both IJN CV lines one is FW (8FP) one BW (8DB) so i can then mix and match on crew set up if needed.

want to put your plus 11's up against my EBVE ones? the better the stats the better the fighter.

also i have tested uk T4's with seaman and without vs US T4's (when they first came out) and they did better with a seaman, so is it a MUST? no, is it something that you will do better with? yes.

8 fly boys (support slots)
1 spare support slot (seaman or maybe engie)
2 R mount slots (2 gunners OR rep/rest OR 2 reps OR 1 rep/resd and 1 seaman(if you use engie on support slot)
1 BO

as for classing to rookie right away yes you should

nope. not necessarily unless you need a scout or want to mine.

Classing a spec force>rookie gives +4 aircraft (which is completely useless) while giving -2 in repair and restore.

Classing a spec force when he hits Ftr (40), DB (45), TB (33) are a must though.

Classing a spec force late gives you a handful of more rep and SD without any loss other than not having 5 extra scouts.

Ok, so it is a must to have +12 or EBVE? NO
Dude, he wants a cv, not the most expensivest but best.

No, Pilots can only control planes, no gun slots etc.
