Noted. I'll fix that. Thanks. my final decision was to remove the lower engine, it allows for retaining the shape of the engines while removing the issue.
I like the overall design. The shapes of the engines balance well with the body. I kind of wish the body would turn up at the tail end to complement the lower end of the front. Also, it's not obvious that the engines could rotate down(they're supposed to right?)
Assuming those engine fans are full on circles, it does NOT make sense the way they're clipping in the engines. It's being displayed right now the fan blades from both fans will clip into each other. It realistically doesn't make sense. Adjustments would need to be made to make it work.
