I was trying to make a world war plane but i couldnt make the wing round and also if u could make it thicker also i dont like the way the blocks look like the look to 'plain' i thought if metal sheets were added were as u could place it on the block or fuselage block and it would cover it with metal or any material and also if u could change the type of fuel used in the fuel blocks e.g oil gasoline desil uranium wierd fuels...ty for listining
