Before now, I did not know how the weighing system in the game worked. My planes were weighing more than planes that are too big to run on mobile, meaning that my aircraft were taking 4 to 7 seconds to do a loop. I just never looked at the weight.

I am working on planes that can turn much faster, simply because I looked at the weight.

My building was much worse than my designing. After this, I will try to work on detail.
