Spitfire Mk.I strange behaviour

I have to test it myself.

One thing I like to mention that should be considered when interpreting the results:

The weight in itself has no direct influence on the speed as such. The only impact on speed is due to induced drag as more angle of attack has to be applied for a higher weight which will increase the drag from which a reduced max speed results. This may be not extensive so only a little speed loss may be all right. The weight will overall be however very disadvantageous for acceleration.

However it shoulf of course not go faster with higher mass.

well said. As with cars, increased weight does not effect top speed, only acceleration. With planes however the angle of attack comes into it.

265mph in a loaded MkI seems a bit quick. Are you sure you were in a descent or just exited one?

Hi,

agreed with Stormcrow

and Flankers question/point was...

I got same 265mph IAS at SL with guns loaded + 100% fuel. Takeoff weight 2756kg

and about 253-255mph IAS at SL without cartridges + 10% fuel Takeoff weight 2330kg.

I kept both speeds long enough to make sure that i'm not in a descent.

That's weird.

Also weird: The Spitfire Ia doesn't achieve +6 1/4 boost at 3000 RPM after take-off, only when RPM is dropped to 2600 the boost increases +5.x to +6 1/4.

S!

Maybe a test server would be in place to gather more information before and after the patch? Could easily compile data to an easy to read form to be submitted to devs. Just an idea..

Aerodynamically that makes no sense...weight has an effect on drag from the wings. Heavier planes should be slightly slower
