410 is capable of pulling more angles with a better snapshot ability and in a knife fight they should be rather equal.
What makes you say that? I don't have any turn radius data, but the wingloading data I have seen does not paint a favorable picture for the Me410.
As far as I can tell, all performance meters, other than perhaps roll rate, go to the Mosquito VI and firepower goes to the Me410, not that either will survive being in the sights of the other.
I will readily admit that I expect the Me410 to dethrone the Mosquito Mk VI as having the best air-to-air gun package in AH.
EDIT:
Based on quick calcs from unverified data:
Wing loading for the Me410 ranges from about 37lbs.sq/ft empty to about 63lbs.sq/ft fully loaded.
Wing loading for the Mosquito Mk VI ranges from about 29lbs.sq/ft empty to about 48lbs.sq/ft fully loaded.
Wing loading for the Mosquito Mk VI in AH with 50% fuel, overload ammo and no bombs or rockets with an all up weight of 18463lbs is 40.667lbs.sq/ft.
If my calculations are correct an empty Me410 barely has lower wing loading than a Mosquito Mk VI loaded for air-to-air. What we need to find out is how the slats and flaps on the Me410 perform.
