It occurred to me that worm motors from cars/trucks such as the wipers, electric window, or even minivan door motors, might be handy to drive the cam ... |

What has successfully been used to detect when to stop a cam? I can think of a few paths, using switches, a sprung piece of metal that touches something, using a hole with photodiode and LED, etc. You ... |

Talked to Steve, sounds like new ESCs will available in a month, or I can grab some of the current bot bitz ESC in US. I will use these ones in the final design.

Been figuring out RC controllers and ESCs.
Looks like Hobbyking will get me cheap 6 channel TX/RX, LiPo + charger. For ESCs need to wait for either bot bitz, or use hacked Hobbyking ESC if I cant g ... |

Finally, what is the time frame for bot bitz coming back for new orders?

I wonder why it is so difficult/expensive to get them.

That would be handy, otherwise I can find someone with some calipers.
Im also figuring out which washers will work to mount the wheels. Ive got one thats too big, and one thats too small. |
