Help Needed in Modifying eVTOL Tutorial Code

[prem naik]

Hello all,

I am trying to modify the eVTOL tutorial code to meet my specific requirements, but I am encountering errors (see the attached image).

Could anyone guide me on how to resolve these errors? If anyone has already modified the code for a large eVTOL aircraft, I would greatly appreciate it if you could share it with me as a reference?

Thank you.
