I flew the Fw190 with undercarriage on quite a bit and brought her in on a number of ocassions for a normal and smooth(ish) landing. Those long legs of hers need flying all the way in. Drop onto them heavy and she porpoises like a Ö. Porpoise!
I think my main problem was having never flown properly flown indoors with another 8 - 10 aircraft airborne at the same time, I kept getting distracted and would then get to a point where I would have to abort the mission. You really need to concentrate!
The P51 I flew mainly without U/C and smooth belly landings where no trouble. I was certainly improving towards the end of the session and landings were not so much of an issue. Managed to purposely buzz the line of pilots with a low and slow pass or two to show off the graphics. Iím sure they appreciated it really.
