After taking a closer look at this picture, it would appear that that Me-410 has a 3 bladed prop. But wasn't the 410 that had the 50mm gun a 4 bladed prop or am I just thinking of the high alt version in general?
No Me410 ever had 4 blades. There was a prototype or two (Me310?) that did, but this was never a production model.
Icepac: I'm familiar with the quality of it. It's "nice" but not perfect. It's also very arbitrary and community-created... So the one from AAA gives the 410B MW50 and 50km/h boost for no reason (just because), and the one from UP/SAS has standard DB601A's. The mk213 cannon loadouts are 100% fictitious, the 3x WGR21 loadouts are 100% ficticious, the Mk108 loadouts are 100% inaccurate....
So while it's "nice" it's also highly subjective and overall I wouldn't trust it as a representation of the AH 410 for the above reasons and one other major reason:
The IL2 servers are nothing at all like AH's arenas. The player interactions, the mission profiles, the action in general. None of it is even comparable. Even when you compare IL2 servers using the same types of setups as your common late-war furball, you won't find similar action between the two.
Where a 410 might have little benefit in the strict layout of an IL2 modded server, in the free-form AH LWA, it definitely would.
