Seen posted on another board, pretty cool.

Do they run them rich to get those flames?

Thanks for posting.

All piston engines produce flames like that if the exhaust pipes are short enough.

That's why night bombers and fighters had flame dampeners/hiders on the exhausts...

As it happens, most of the Mosquito night bombers didn't. You see flame gear on the very early Oboe markers, but by late 43 all the night Mossie bombers seem to have stub exhausts, including the low-level markers of 627 Sqn. The night fighters retained the dampeners, apparently the extra light interfered with aiming, and the intruder craft didn't want the ack gunners to have a clear target while they stooged around LW fields.

Nice video. I am a bit worried about the fate of the Mossie.

My understanding is that for the bomber Mossies the performance hit was judged not worth hiding the flames.

For most of the war they were fast enough to make it a mute point. For the NFs it was much more important to hide your presence from enemy eyes and guns. Also on slower bombers like the Lanc flame dampeners were essential for survival.
