The only comment that immediately comes to mind is the height of the vertical fin and stabilizer; compared with the fuselage it seems small and perhaps lacking in area to handle the horsepower generated by the engine. That said, the drawing looks servicable and the specifications within acceptable limits, except maybe the weights - my instincts tell me that either the empty weight should be less or the max weight more, but I cannot put my finger on why.

Concerning the weight I used the B7A as a guidline as it has some similarities with my plane (size, role). You are maybe right with the weight, though the loaded weight isn't exactly the max. takeoff weight.

The Finsize is indeed an issue, but I decided to keep it like that with this model (I willl change it for the 1943 or 1944 version though.) Chosen designers are not as experienced as their european counterparts with aircraft engineering, so design-flaws sometimes happen.
