Project of the Japanese submarine I-400 Sen-Toku type, the truth is that my tablet does not support that much, but I try. Since I cannot install mods to see underwater, I limit myself to making the submarine with a low profile. build a simple plane in the same job, to be able to take off from it with a catapult, and the truth is, I don't know if it is done like that, but install the main cabin in the plane, to be able to fly and do reconnaissance. New project for me, I hope to install torpedoes, more details in the fuselage, gain the autonomy of the ship when the plane flies, configure the catapult well, cranes to raise the plane, etc, but I will do it in a new device. like it.
Navigation notes:
Important !!!!! Take off the plane, start the engine, increase power to the maximum, joystick movement kept fully backwards, to ascend, and then actuate the catapult! It is a bit difficult, but it ends up mastering.
The catapult is an adaptation of a work I saw by a great builder, @Urya. But I had to adapt it and remove movement, although the original is much better, I hope you can test it.
