u could use the method of a rubberband and a thread spool sort of like the rubberband airoplane put your spool in the middle of the rear axle and put your front axle through the rubber band staple the other end of the rubberband to the spool and twist the wheels backwords towind it up hold wheels and set on floor and let er go what you need to worrie about is to much thrust as to throw the egg out unless you are able to strap the egg in if not you may have to put a seat in something with a high back
