Talk:Ro.43 Reconnaissance Seaplane/@comment-26848183-20160304015241

So the main trade offs are these?

Ro.43 pros: +1 firepower, +1 evasion, and really cheap to upgrade compared to the Observation seaplane.

Observation seaplane pros: +2 LoS over the Ro.43

The seaplanes look very versatile as they can be used on many ship types, and I'm thinking about focusing on upgrading these before I start upgrading the new proto-cannon improvements.

When is it better to choose one seaplane over the other? And how many of each upgrade do you recommend upgrading?

The artillery spotting chance bonus should be a lot smaller compared to estimate written a few comments earlier. I highly doubt that the difference between a single Ro.43 vs Observation seaplane's ability to trigger artillery spotting is as high as 4%. The Japanese wiki's VERY rough estimate seems to be around 0.05 to 0.08% artillery spotting chance bonus per fleet LoS, though it looks like they aren't very confident with the current estimates and a lot is still unknown.
