The little RC car just came. I'm giving it a full charge now. Initial thoughts - It's got some good power. It's the right size (Looks small enough to fit, but long enough to not get turned around). Range on the signal seems good too. I think it'll work...I'll try it as soon as I get a chance. The only challenge will be keeping it upright, but I feel like if it lands upside down, I just pull it back up and try again. I need to be aware enough of the line tension to know when it's falling down the vertical drops so I can catch it and lower it down vs. just letting it fall. It's light, but also cheaply made, so it may not survive such a fall.
