Just wanted to say hi y'all. Its been awhile since I've posted but I'm still flying CFS2 exclusively in the Spanish Civil War theather. I have been trying to come up with the perfect 635hp Jumo 210D airfile for the Bf109B-1, and then I wanted to make appropriate incremental improvements on subsequent 109s up through the E model. The problem I have in getting this project done is three fold; 1) I'm not an expert on airfiles, 2) every 109 airfile I have seen seems to have been originally created for the Daimler-Benz engine rather than the Jumo motor, 3) and probably closer to the truth is that ADHD gets in the way and I get side-tracked.
My reason for wanting to do this is historical. Mind you, I have never been one of the rivet-counters around here but this was the period during which the 109 was being perfected for mass production, and its nemesis, the Republican flown Polikarpov I-16, was constantly being upgraded. The first few experimental 109s, considered the A models, were built for the 610hp Junkers Jumo 210A motor, although the very first had a 695hp Rolls Royce Kestrel engine. When the 109 first saw action in the SCW, the varient used was designated as the Bf109B-1. With their 635hp JumoD engines, wooden fixed-pitch propellers, and dual cowl-mounted 7.9 mm MG 17 machine guns, one could imagine they had to adapt, just as their future American foes would, by slowly gaining superior altitude and then utilizing gravity to gain speed and jump the I-16s from above. The 109B-2 was a short-lived upgrade utilizing a Hamilton variable-pitch metal two-blade propeller, through which a third machine gun was housed, and a 640hp JumoE engine (Actually, I found different sources who suggested the engines used in the 109B-2 were the JumoD, Da, and E models.) The Jumo E engine quickly gave way to the gave way to the 670hp Jumo 210G engine. Another short-lived 109 was the C series with models designated C-0, C-1, C-2, and C-3 sporting a 700hp Jumo 210Ga engine and two extra wing-mounted machineguns. It was a better performer because it gave the 109 fuel injection and retained the Hamilton propeller. The Bf109C-2 variant featured engine-mounted machineguns. The 109D also saw time in the SCW war and was beefed up a bit to handle the more powerful new daimler-Benz 600. However, the 109E was developed so quickly on the heels of the D model that the Germans decided to send the Ds to Spain with the same old Jumo powerplant. Apparently, a few of these new E models were sent to Spain, but my sources say they were never involced in battle their.
If you know of any well done early 109 airfiles with jumo engines or can make one please post. And thanks!
