We can change the Mix also in the 109 (the central of the 3 levels near the throttle).

Today I tried again with my friends in multiplayer (with the "mod" finally we can fly together, but the multiplay "seems" limited to 6 players, have you ever hosted for more humans?): flying in a inflight 109 (former AI) I reached the 5 km before any shake. Maybe I had the first shake after x seconds from the airplane selection (takeoff/2,5km = 2km/5km)

I really don't know: anyway we tested some SpitIIa vs 109E4 and, I'm really sorry to say it, but the energy management seems to be AGAIN the one of IL2 version < 4.10.

It was our first real test, so probably we are still noobs with the full EM: anyway the 109 seems to lose tons of energy in a candle.

I'm still optimist (but please I can't wait AGAIN 10 years to have good FMs): for now the priorities are others I hope.

The Spitfire Mk IIa is modelled quite well for a +12 lbs boost version (even thought he boost shows as +8 lbs). Unfortunately the 109 is about 30-60 kph too slow at all altitudes.

That would explain why your 109 lost so much energy, it simply has too little power.

how can you change the mixture in the bf?im only able to set it either to 100% or 0% and nothing in between

Two stages like you describe: maybe is something like 100% - 80%

@ICDP probably you're right!

well maybe you are right.but reducing the mix doesnt help anyway.i climbed to about 7000m.on that altitude the bf climbs like my grandma goes upstairs. puffs coming out of the exhaust pipes every second and the whole plane shakes like Michael J. Fox.(sorry for that one)i reduced mixture and the engine almost stops.

Spitfire and Hurricane seem to have the same problem. I thought this is caused by "less than 1 g cut outs" but it looks like a more general problem.

It's identical for a constant pitch prop too. The pilot just has to do the work is all.

I guess the M20J defies the laws of physics.

As I understand it the lever currently labelled Mixture control in the BF109E3 was actually there to alter the timing purely to allow burning off the plugs (removing Oil fouling) and was only done on the ground. Once in flight Fuel injection did its thing. In short the 109E3 didnt have any mixture control.



I grew up understanding Max power and Speed was MAX BOOST and MAX RPM

I did some testing with the E-3 today for speed at 0 and 5 km rated altitudes, and climb between 0 and 6000 meter.

Refer below to my findings, compared graphically to the actual Bf 109E Specification sheets of 1939, found here: http://www.kurfurst.org/Performance_...chreibung.html
