Hello fellows, I have one question. Two german pilotes of the III.JG 77 in Rumania 1944 claimes a reccon-Mosquito. One was Hans Riedel in early August ( mentioned in Prien, JG 77 Volume 4 ), the other claimed by Johann Twietmeyer ( a diary of him actually read in german at Youtube, bacuffz ...

Hello tomo pauk, this are only calculated datas. With 1.42 ata the F-4 would be a very great performer for this time, especially in climb. But in my opinion this was never realised for frontline service. I imagine when the frontline pilots in the end of 1942 must exchange their 1350 PS F-4 for...

Hello thedab, for a long time I had the same idea in my mind. Now I had the conclusion for me that the 1.42 ata for the 1350 PS never was realeased. In my opinion the stated performance with 1200 PS at 1,3 ata for the F-4 was reasonable. Detlev

Is there really evidence that the italian DB 605 had 100 Ps less than the german original?

Siegfried, thank you for this informations. In case of the TEL I know that there was a limit for normal fuel at about 87 octane.That means that even more TEL has no impact to the octan index.For higher octan you must add iso-octan or alkyl. Regards,Achi

Thank you for this information,Steve.

Hello Steve, Chris Starr writes :"...the first breed of methanol 605s used precious 96 -octane C3.However,the realities of fuel supplie in Germany meant that extreme pressure was applied to DB to develop further engines capable of using regular 87-oktane B4 and,when the firm introduced a final...

C3 fuel was rare,when an engine run on B4 this would be the choice.Safty margin could be the reason ,but than at great expenses.

I am relating to the version with 1.42 ata boost and without water-methanol injection .

hello members and guests. I dont know the reason why the DB 605 AS of the Me 109 G requires the C 3 fuel .There is no more power output and no higher boost.Later the K 4 was satisfied with the B 4 fuel. Thank you for answer. Regards,Achi

Hello at ease, I am very certain that the vertical axis is calibrated in meter per second ,here the Do 335 have a rate of climb of about 9.5 m/sec or 1870 ft/min at groundlevel.It seemes for me that the specificationes at the "GM 1" are consumption-values , in this case Gramm per second. Thank...

Thank you all for reply.Exchanging with Yak 9 is reasonable for me.Regards,Achi

Hello members.On the webside virtualpilot .fi one can read that Kyosti Karhila downed two Mustangs over Vatnouri(4.7.+7.7. 44).I cannot find this location,but I assue it is in finland.My question :how comes a Mustang over Finland?Navigation error?Regards,Achi

Hello VG-33.What means "ToT" and "AoA" ? That there is a difference between calculations and the reality,especially in case of turn-abillity,is clear for me .Nevertheless in my opinion it is a valuable contribution .Sadly,I have not the ability to calculate this.
