Thanks! I've thought about wind speed, and really, I don't think it's necessary. On a real sail boat, your response to variable wind would be the tension on the backstay, the amount of sail area (through reefing) and potentially the jib sheet car positioning. None of those are available on an RC sailboat. Your only other option is to spill air from your sail by overtrimming, which you could do in response to just the heeling (roll angle) of the boat.
