Negative G's
 
Ive never flown a spit in real life, but I am a corporate pilot and have flown a gravity fed- non inverted fuel pump aircraft: a stock Cessna 172 into zero G's just for fun. Does the engine quit instantly? Of course not, fuel remains in the carburetor long enough for a few seconds of zero or negative G's.

I haven't even played this game yet (waiting on a real, final, playable release) but thats my 2 cents on the issue.

I have never flown a Spit in real life either.:cool:
I Flew solo in a C-172 for the first time in 1959. I fly on.
I have flown a fair number of carburetor fed, piston engined aeroplanes.

In my experience.
Pushing the aircraft's nose down moderately should not cause the engine to immediately quit.
Airspeed should not be immediately, and drastically reduced, apparently directly related to RPM.
Mass and Momentum, should serve to keep things moving along.

In my humble opinion Eh! :)

You are quite right, it shouldnt, which is why it was fixed in later version of the Birtish fighters. But this is a factual known issue with these planes due to the lack of direct fuel injection, which when put into negative g's cause the fuel to be forced out of carb.

Now whether this effect in game is too much or too little is something I have no clue on judging.....

Where is Miss Shilling's orifice when you need it ;)

Miss Schiiling didn't have an orifice at the time of BOB :)

Dairy.air is well aware that it is a factual issue, which is why he is using real life facts (he flies a cessna with a carburreter fed engine) to suggest that the negative g cutout is not modelled correctly.

S!

And how about this? "Miss Shilling with a small team travelled around the countryside in early 1941 fitting the restrictors, giving priority to front-line units. By March 1941 the device had been installed throughout RAF Fighter Command."

I noticed a performance increase in this patch, and also the allies plane rear view mirrors are finally fixed to not cause the FPS dips.
