Are you planning to implement HybridMotor drawings in this PR or it will come in a future PR?

Good question. I'm currently not working on this. Implementing draws for hybrid motors would depend a lot on te current implementation of liquid and solid, therefore I'd say it is better to finish up those first.

To be honest the code is far from ideal. Both rocket draw and motors draw would benefit a lot from code refactors.

Let's see how these go in our roadmap. Code suggestions are still welcome in the meantime.
