Engine keeps quitting

[moggel]

I must be doing something wrong here because I can't do performance climbs without killing an engine. I've been following the Climb Checklist for performance climb (+9 boost, 2850 rpm, cowl flaps closed, 150 mph) but so far I haven't managed to go higher than angels 13 before one of the engines quit. Oil temp is, at that point, somewhere between 60 and 70. I haven't found any advice on how to use the mixture in the manual so I left it at RICH.

 

Any advice?

Check water temp aswell. 

 

If needed open radiators. If you keep temps okay, you wont have any issues. 

 

Also, do you climb with 150mph? Thats quite slow given optimal climb speed is 175mph.

Yeah, seems I need to keep cowl flaps open durin a perf-climb, contrary to checklist. I do go for 150mph with 9+ boost, as that is stated as max rate of climb (page 102). 175 is optimal for range, as I understand it (with 2650 rpm and 7+ boost. maybe I misinterpret the manual?

Okay, sorry. Forget about 175mph. You are right, 150 mph max climb. 

 

So I guess just watch temps and you should be good.

I've been keeping the rad flaps open for the entire duration of flight just to keep the engines happy, even with 0C outside temps.
