There are much better things they can be learning on, much bigger fish to fry. If an engineering student can't think of anything better than we are going nowhere. A junior high student should be able to throw that together.
You can't even call that a hybrid for starters as it's more of a simple twin power system... if you are going to put in effort to put that together, why not use a smaller 4-stroke rc engine on a small BL motor, generating power for a small charging circuit to charge a low impedance battery pack... to power the motor. That would at least be worth the effort. People have lost their ingenuity and originality these days sorry to say. I might be tired but that is the way I feel.
