It would be pretty neat if you could have more readily available parts that can also be customized like cockpits. I thinks glass cockpits should be added for the historically correct planes that you'd make. I am making a F-4 Phantom on mobile, but the canopy is the main issue! If this does not get implemented that is fine. It is just without mods for mobile users, you are limited on what you can make. 

God bless.
