Help Needed: Hybrid LEGO Technic Drivetrain with Clutch + Dual Input (Pullback & Motor)

Build right now: https://imgur.com/gallery/kBNa4rE

Hi everyone,

I'm currently working on a hybrid LEGO Technic drivetrain project for a university assignment, and I could use some help/advice with the mechanical layout and power delivery.

 

What I'm Struggling With:

Where to go next? I've mounted an electrical motor that connects to a gear which can rotate and possibly power the pull back motors. I'm stuck what to do from here and what to build next. Not sure if this prototype now is functional. There is also a flow chart I've posted that we must refer to. https://imgur.com/gallery/6Zin5z6

 

I’ve got most parts available (PF motor, clutch ring, bevel gears, bushes, Technic beams, etc.) and have built a working 4-wheel frame. Right now I'm finalizing the drivetrain.

Any feedback, images, or build references would be hugely appreciated. I’d love to learn how others have approached something similar — even if it’s not exactly a hybrid.

Thanks in advance!

this guy has a motor and a pullback motor connected together very nicely. It might help!
