Um, no. That's an amateur principle.
It's worse than that. You have to store the fuel somewhere, and depending on how efficient your engines are not all of it's getting converted to motive power (the perfect engine caps at 88%. This isn't a real-world measured value either; this is the actual calculated "perfect system" cap).
So, given that you have to fight against wind resistance, the weight of the actual flying brick, the weight of the fuel, the weight of its ammo (I mention the last two as I'm aware that they'll deplete throughout).... No. Not gonna happen, sorry. No matter how big your engines.
Take a gander at.... Idunno, most of the non-Marine Aeronautica range for an idea of vehicles that MIGHT work (I say might). Hawk Wargames also do it well, sofar.
Anyway, a question for the 40K players.... are you guys really okay with the concept of the game becoming 28mm Epic? Because that to me feels like where it's going. Planes, ICBM's, big tanks etc.... to me it doesn't feel feasible at this scale, so to get it to work you have to expand the playing area & points size.
