To see what all the fuss is about, ie are we talking about

10?
20?
30?
40?

In doing so I found some 109G data but not E data, here is the sorce

http://www.wwiiaircraftperformance.o...9/14026pg9.jpg

Now it is really hard to read the speed axis, but it 'looks' like it goes

520
530
540
550
560

If that is the case, than the 'difference' in speed between open and closed is..

5 kph

Which is well within the pilot error noise

Thus, IMHO, the only way to detect this small change is to log the data and account for the pilot errors

PS correct me if I am wrong, but the rads on the 109 changed alot from the E to the G, so, assuming Jerry did a better job on the new rads, we can only assume that the older E rads caused more drag, and thus impacted speed more. But, even if the change was doulbe this, say 10kph, it is still well within the pilot error noise
well that document is really hard to read....however how do you come to the conclusion of 5kph differnce?

maybe i read it wrong....there are two different graphs which show the speed per rads setting.
however both show a straight decreasing line with the same angle...so the difference remains the same.
the lower line shows a speed of 555kph with 50mm opened rads, and only 505kph with 310mm opened rads(which is not fully open).

50kph difference between not fully closed and not fully opened rads...
