Junkers Ju 390

I always wanted to do an old prop driven 6 engine bomber so behold....! The leviathan that was the Junkers Ju 390.Derived from the smaller 290, the 390 was conceived as a long range multi-purpose aircraft and was one of the more realistic options for the 'Amerika Bomber' programme in the fact it was actually built and flew. (That and it didn't rely on space travel, super weapons or unreliable jet engines!)There's all sorts of claims of the 390 making mammoth flights to Cape Town, New York (albeit 12 miles from the coast) and Japan during the latter stages of the Second World War. There's even theories that suggest a second made aircraft flew to Argentina. For those interested the internets abound with such theories, some more ludicrous than others. Did the weight in fuel for such a flight have limitations on the already overstressed airframe which essentially was a lengthened 290? Most likely. Would a regime in its increased desperation attempt to attack a target to score a propaganda victory? I would think so. As much as this can be debated there's no hard evidence unfortunately. Enough rambling on with SimplePlanes!Handles slowly due to the 5000+ gallons of fuel onboard - I tried to replicate a realistic fuel load for an amerika bomber. Reduce this and it's surprisingly nimble to fly. I have attached JATO pods as I feel this would have been a realistic option for such a heavy bird (and potentially bombed shorter runways) AG 1 activates them. When you get airborne AG 1 before you detach them (AG2) again and let them spool down for a few moments otherwise you'll end up with some rogue flying missiles! VTOL down to open bomb bay doors before releasing a hypothetical nuclear device or more realistically a propaganda scoring smattering of bombs. AG3 deploys 'chute and fully throttling fully back will engage speed breaks.As ever it's a joy to build and develop these things.
