Help Needed: Hybrid LEGO Technic Drivetrain with Clutch + Dual Input (Pullback & Motor) Motors available: https://imgur.com/gallery/XdUbU8f 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!

Help Needed: Hybrid LEGO Technic Drivetrain with Clutch + Dual Input (Pullback & Motor) https://imgur.com/gallery/XdUbU8f 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. Goal: Build a 4-wheeled vehicle where two different power sources (a pullback/manual axle and an electric motor) can engage a central clutch system to drive the same rear axle. Key Design Elements So Far: Rear wheels mounted on a yellow axle Medium PF motor to power one input Manual pullback input via a second axle (non-spring based) LEGO clutch ring + two red clutch gears to switch between inputs Red 20T bevel gear to drive downward to the wheel axle Tan 12T bevel gear on the axle for 90° torque transfer What I'm Struggling With: How to mount the motor securely while keeping it aligned with the left clutch gear Making sure bevel gears stay meshed without slipping General layout tips — is my frame too narrow or short? Any better ways to link the clutch output to the wheels 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.
