This is the second installment of reverse engineering of the cheap helicopters that can be had on Amazon.com or your local toystore.
The first iteration went over reversing the IR that was sent on the IR LED excessively. This time, the good guy latched in a logic prob and got the raw packets being sent over IR. Some great skills displayed here. You can think of it as a tutorial with poking around with a logic probe. The packets being set and how to control multiple channels are discussed.
