Those are interesting points. Ideally I am looking for something that I can run around in front of the house on the street and up onto the lawns maybe chasing the kids around so it has to run fairly well on grass. I like the idea of brushless, lipos, fairly fast. How long will the typical battery run me just messing around? My heli lipos last me all of 7-10 min. Interesting point about hpi. Not a big fan of just cars. Looking more for an all-terain something or other that can jump around and land relatively upright....is this too much to ask for?
