Bf 110C issues

[kubanskiloewe]

made a map (channel) without windinfluences took a 110c4 with half fuelload and full weapons.
I flew 2 time always with full throttle (1,32ata) and 2200-2500rp`m´s
Groundlevel over sea (ca100m) i reach 440km/h; it doesnt care if engine rews with 2200 or 2500....but slow acceleration

4500m the pressure drops and i reached near 400 IAS (ca 500km/h) and cooler flaps didnt made a difference to me if full open or near closed

than it takes long time to get 6000m with loosing much power and get only 250IAS
never reached 7000m.....

i noticed outside eahaustflames went more to red with height.... probably the auto mixture doesnt work well; this could also be the reason for power and speedloss.

climbrate is ok from 0-2000m (ca 2,5min with 200-220km/h IAS) above the climbrate sink constantly and in 4000m 7min where gone....always with full throttle 1,32ata

doing a 360° roll at 4000m in ca 4-5sec.

acceleration in a dive is poor or not better than 1mot´s ....think i still can follow in a spitII

the worst thing on those 110´s here is loosing control and speedmeter goes crazy above 500km/h IAS at any height....f.e. in 2000m ; think at 600km/h the rudder is gone
