20 or 22 was my recommendation as I recall. It isn't used enough to be ENY 15. Shortly afterwards HTC revised the ENY numbers and all of the aircraft I thought had significantly off ENYs were changed, except for the Mosquito. It seems HTC wants the Mosquito at ENY 30. That being the case, ENY 40 for things like the Hurricane Mk I seem too low.
The Fw190A-8 is used much, much more. That plays a not insignificant role in ENY value.
Fw190A-8 is also faster at altitude and once the Mossie's 5 minutes of WEP are done.
I agree one of the most used fighters IRL in ww2 are well-used in AH, despite its shortcomings, mostly due to its guns (which is less effective than the center-mounted Mossies both in range and damage.
The problem is a normal fight is all over long before those 5 minutes expire.
If the Mossie pilot have any smartness built in him, he only use it in bursts and can recharge them, while a overheated A8 more or less has to go and replace the bird for a new one, since 190-A recharge time suck.
I regularly fly with Bozon as a wingman and I struggle to keep up with him, and have to select fights much more to have any chance of success.
If i switch to the 190A5 its quite the opposite climbing all the way to war zone.
