I don't know why RU-vid showed me your channel, but I am glad it did. I enjoy your problem solving! Also, your editing and video effects are great. Thank you for your work.
how bout rear wheels can spin independently? make it 2wd, front only. both left n right rear wheel can turn at different speed, making it easier to turn
So..... If you want flying Mini4WD just use 3.7 bat+plasma dash motor. What if you make that motor place on horizontal mode and lock it from upper side
