Flying and Skip Bombing the Blenheim on Cockpit Instruments

[Feathered_IV]

I'd been following the ATAG video and opening the rads once I hit 200-230 degrees and 40+ for oil temps. Props are in fine pitch and the engines start to kill themselves as soon as I throttle up more than half way. Just laboriously re-downloaded and installed the game anew, so pretty positive the issue is with me. I'm about to surpass Hartmans tally of allied aircraft though, so I'm hoping to get it figured out before Fatty asks me to spend the weekend at his hunting lodge...
