Manfreds L1049G/H models worked fine for me in P3DV5. Both the Tip tank and non tip tank version came up well. They were the native FSX versions and the VC mods available worked ok to. Straight drop in or port over. Just make sure you have the Doug Dawson 64 bit sound gauges thats all. They look and fly well as far as I can tell. Here is a screen of the old girl over Sydney this morning at 7.10 am. ORBX AU2.
There are some minor issues with the aluminium textures and the EA which makes some parts look black when they have a shadow from other parts on them that's all. The FE position and switches, gauges and the VC controls all worked for me.
A real pleasure to see the MJ Constellation, which is a Classic transported into the new sim world a credit to the original design and the team who made her.
