Paul Allen's/Flying Heritage collection's authentic Bf-109E warmed up & flew last Saturday.Its Daimler Benz was worth waiting for...








it was floowed closely by 3 very pretty P-51s includinga D-Day Marked Razor back:



I might make one small comment relavent to AAA site Mods: on all these aircraft there was no plume of exhaust smole ( or flame) on engine start....of course I will keep it in my planes thanks to AAA because it does look pretty cool.

James, do you know if there is a video link to this somewhere?

Re the engine smoke.
You'll find (I think) that the smoke/flames from the engine is due to the wartime aircraft running much richer mixtures than the modern aircraft use.

More fuel in the cylinders produces higher power, but also reduces engine lifespan. Most modern restorations run lower boost settings for the same reasons. Im also not sure that the same fuel is available.......

Just my understanding of it, and I'm more than happy to be corrected if I'm off the mark, but the smoke at start up is actually accurate for wartime aircraft... And if you've ever seen an aircraft crank over with a very rich mixture, you'll see the flames from the exhaust as well.

The link below is what looks like a Merlin engine at start.. (Not that they were 2000hp...)

Wartime film tends to confirm your comments...and as I said I LOVE the new mod( and engine sounds too)

Interesting point..
Why does that P-51C have a fin fillet?
Is it a converted D?
