After building the handcrank plane, I wanted something that was much more capable of an immediate vertical climb as I wanted a y=600 mountain top base in my survival world.
You steer it by tipping the center of gravity off balance enough that the wings can catch lift. I've calibrated it so that the weight of dirt is perfect for this, as in survival you need to be able to destroy it quickly from a seat (lowered break time, similar to underwater) and for you to not care about losing the blocks to them dropping over the edge. Lighter than dirt and it wouldn't catch enough angle to glide, heavier and it drops like a stone without gliding. It can be calibrated for other weights but dirt is the most convenient.
Also comes with the added bonus that you can see much more if your surroundings than with the handcrank plane, and spend more time gliding slowly before reinput is required, so it's all much more scenic.
