This one has been hashed out too many times to mention, here's a note from 2009:
http://bbs.hitechcreations.com/smf/index.php/topic,69958.15.htmlEssentially, no.
That plane was in development from 1938 to 1945 and was shelved as a total failure and waste of resources with the only hopes for it's being serviceable pinned on variants that never saw combat (e.g., the A7). While many have tried in recent years to recast it as "misunderstood", that is, uhhhmmmm, less than accurate. The Germans did everything they could to make it work and after 7 years of development said "well, ok, that was a wasted effort." As late as 1945 Heinkel was, even after being ordered to stop, trying to show off a 4-engined version that might have been a useful bombing patform. He called the twin nacelle version "that cursed 177" as I recall. Since he designed it, I reckon he knew something about it.
Its service record as a Bomber is so insignificant as to be laughable, it's only real use was as a transport, then turned into cannon-equipped raider/strafer. No real service record of note exists as abomber with few raids and even fewer sucesses. That is to say, at the end, when desperate to stem Ivan's rush, like 300-400 of them rotting on Tarmacs because of their uselessness were shipped to the Eastern Front to use first as transports then as ground attackers. If Germany had possessed 400 serviceable Gotha bombers from WWI they'd have shipped them to Russia for the same uses. I don't think any flew to speak of after Summer 1944 did they? One bombing mission they sent like 14 to bomb England (14 aircraft, sound like a raid or a trial?), ten caught on fire returned/never lifted off, the remaining few dive-bombed a pasture.
Loss of coolant was fatal, and arguably fatal far sooner than on other WWII AC. If the fragility of that AC is modeled, the hue and cry and whining about it's worthlessness will be immense, causing everyone to want something serviceable like the Do-217 instead. I would say:
Skip point A and go straight to modeling the excellent, sturdy, workmanlike Do-217. More AC built, wider use, vastly superior in level and dive bombing recorded use. 8k loadout, fighter variants available, . . .
Simply put, no honest or reasonable comparison would select the 177 over the 217.
Cheers,
