the elevator is also very twitchy with the Spit, considerably more than before, has caused me a lot of missies from dead six, i end up fine tuning with the vertical trim on approaches and even so it's not easy; regarding rudder, it's the same situation with a sudden response on slight inputs. i find the control surfaces' response more sluggish at high speeds, although maybe more with the ailerons than with elevators.

as for the CEM questions, about WEP (boost cut-out in my case), well i don't think i can reach 2min at 3000rpm on cut-out without blowing the engine, and that with slight variations from level flight; i may fly for quite some time with cut out on 2700rpm, or i may be unable to sustain it at 2640rpm, it really depends on the given situation and speed; speed is another variable in the fray, i have been squeezing 300-310 mph at level flight with rad at 30-35% with cut-out at 2640rpm and getting away with it, i think because of the extra speed meaning extra cooling.

furthermore, i've realized there seems to be some random factors on the engine's thermal behavior; also there's a tendency to overheat when reaching 10000ft, sometimes forcing me to reduce rpm just below 2640rpm,or to reduce boost (throttle) which makes sense to me, as the air should be thinner and the prop would get less opposition, in turn heating up the shaft, governor and engine itself. right?

last note: i've read extensively that in RL the Spit was really childish to fly, "anyone could fly a Spitfire", so i don't think it's harmonic behavior is that far off... slightly overdone probably; what may be lacking to destabilize it some more is some wind conditions and different air masses with dissimilar air density
