radiators have no influence on speed

No prob!

Oh I understand that, have for years

What I don't understand is how guys like David can come here and make baseless claims.. Such that he had no idea how much the speed should be affected.. but did that stop him from making the claim? Nope! Now that we have some numbers to get a feel for the affect.. I get a good laugh at David's expence that he 'thinks' he can detect an 11kph difference that he didnt even know as 11kph until I provided him the data.

you still dont know that its 50kph difference and not 11...man im getting tired arguing with you...

and even if it was only a difference of 11kph, why shouldnt one be able to detect it???

C'mon guys there was enough blood wasted at the time those events took place. No need for anymore shredding here

+1

sorry ace if i upset you...that surely wasnt my intention with this thread

I think we are talking about two different things.. I am saying the difference in the two graphs is a constant ~11kph

You can, but not with the naked eye! You would have to log the data, so you can take into account the variations of flight, because the fact of the mater is the speed vary as you fly due to you making small altitude changes.. That is to say YOU ARE NOT CAPABLE OF MAINTAIN A PERFECT ALTITUDE !!! But don't feel bad most cant! Thus the variations in speed due to altitude changes are on the order of 30-40kph. So, the 11kph falls within that range, thus you can not desern which is which unless you also plot altitude

yes but these constant 11kph is the DIFFERENCE BETWEEN THE DB601 and DB605 engine!

Now I would like to know if someone has made tests:
Full throttle, optimal rpm

what are the durations before ruining the engines depending on rad setting.

100% open, 95%, 90% ...

Bingo!

And with that said providing a track file is the min requirement to be taken seriously..

And log the data as you fly and record that track file if you really want to do a good job!

In IL-2 you could replay the track file and extract and log the data at a later date..

But I don't think you can do that in CoD! I am pretty sure you have to log the data as you fly the mission!

Still as I noted the speed can varry by 30-40kph due to altitude changes.. Assuming you can hold it pretty steady, more if you cant! So your 50 would/could still be in the noise. The only way to tell is to log the speed and the altidue, than you can 'see' what is going on

well ace,if you have trimmed the plane,the 109 becomes really steady.you can fly for miles having the crosshair focused on the horizon without any further input,so the differences in altitudes and speed are only minor, therefore a difference of 30kph would be clearly noticeable.
