The reflections are something that people love or hate , i had someone ask how to do them like that and others who want them gone , if you would like to get rid of them , make a copy of glass_t.dds name it refgl.dds and they are history.
Performance of the plane above 10000 feet is at its best continous rating with the mixture levers set to rich ( 80% ) and props at full , and you can climb 1200 fpm at 280 kias ( true ) for ever with throttles at 87% .
If you run this aircraft at full throttles after about 8 minutes your performance will start to degrade and after about twelve minutes there will start to be smoke and detonations coming from the engines , you can feather the props if that happens and cut the throttles and dive down to cool the engines off.
This bird had its turbo's kick in with full power and was good for five minutes in WEP mode according to the book , i set it up to stand that and then start to damage the engine slowly , you can set them on fire if you keep it at max long enough , you will hear them start making some nasty sounds and see the flames .
PS/Hint , the lights on this plane are run best using the light bloom on setting.
