I was trying to build an automatic pumpkin farm using slime block flying machines, only to see that said machines don't work as expected. Instead of flying all the way to the end of the farm, they wander around and usually come back to the start. Sometimes they don't even leave the start! The video shows the design I'm using, as well as the result: https://drive.google.com/file/d/1rF_AnbtmijRBRDsGUqIpkA-l2rLUeXCL/view?usp=drive_link
