i'm not ready to start spending+building but longer post time = more feedback: intending to build some very small rc vehicles for ground use. i don't care if they are cars/wheeled or legs/walkers. it needs to be small, have a low profile, and i'll be plopping a micro IR camera on it. https://www.banggood.com/New-Smalle...00TVL-Pin-Hole-Camera-With-Mic-p-1170608.html the function is anti-cricket. needs to go around the outside of the house over various terrain (nowt too challenging, a hot wheels would probably cut it) and under various clearances. 1/2" would we awesome! reason i ask is because knowledge of the marketplace avails prefab wheels chassis et c. ... i haven't seen any rc cars that are too small yet, none like a hot wheels. (geraniums and molasses cups work well but "active defense" is really prudent in this campaign) post em if you got em!
