This guide will let you know how to design a Redstone Plane in the Minecraft game. In order to make a Redstone Plane, place a slime block up to the height of 18 blocks and then place the slime blocks, observer and piston in the same way as shown in the image below.
Add one observer in the middle and a piston and slime block in front of it.
The next thing you have to do is to add a minecart at the top front of the plane. Your redstone plane is ready now and it’s the time to make it fly. Use flint and steel to ignite the back.
You can see your Redstone Plane flying up in the sky.
