does that mean majority of the Luftwaffe engines had more or less than 3 valves?

I don’t know, though it would certainly be easy enough to do the necessary research. But a three-valve configuration is far more unusual, generally, than four valves (like a Merlin) or two valves (like all U. S. radials).

Sort of like three-cylinder engines, which do exist, but there are far more twos and fours…

On the racecar engines with which I’m familiar, and I assume this is also true of Reno racers, water injection is used simply to cool the combustion chamber, as one might intuitively assume, which allows higher boost from turbocharging (on the car engines) without detonation.

I know nothing about how it affect a turbine engine.

Avoid like plague, Resorcinol,

Hey, I built an entire Falco using Resorcinol! Been flying over 15 years, now in Australia on its second Ozzie owner…

I’m starting to get bl**dy annoyed with all of the pedants on here lately.

Hardly seems pedant-ish for someone to question your implying that water-injection systems utilize some powerful fuel…even if they weren’t aware that you were actually confusing water injection with a system that is used to run an emergency power unit.

Red Tails cost $58 million to make, and they spent $40 million in marketing, and it’s box office is 49.9 million so far. Pretty big loss.

Yes, you’re right,of course. I guess what I was thinking was that Lucas paid the marketing expense for the film, since no distributor would touch it, and he made back that $40 million and then some.

“It was a ‘Boys Own’ adventure movie, based on a true happening. It was entertainment” How come it wasn’t promoted as such then?

It most definitely was promoted as a teenager’s adventure film. George Lucas gave any number of interviews, in print and on TV, in which he specifically said his ideal audience was 15-year-old young men in need of role models (i.e. black and probably from a single-parent household). He wasn’t trying to make a documentary and he wasn’t trying to make a film for 60-year-old nonpilot rivet counters.

I’m a member of TAI (Tuskegee Airmen Inc.), so I take somewhat personally the constant ragging of this film, which in fact turned out to be strongly popular among young audiences and made back its cost and then some (much of which Lucas had footed himself), which surprised many naysayers. Lucas also contributed handsomely to our organization.

Well, it’s confusing…if you watch this news video, 55 seconds in the manager of the Front Range Airport, where the crash occurs, speaks in some detail about the Gypsy Moth that the pilot had recently finished rebuilding, and which he was flying when it crashed:

I’m guessing the FAA is wrong. Imagine that.
