Attempt at cheap homemade version of Harmony

[Oran]

I didn’t now about UBECs, seems like the way to go. The servo is under enough stress as it is without being driven beyond its rating, much as I would like the extra torque. I currently only use the 5V supply for the servo, could put a USB socket on it for phone charging but haven’t. Some very good little modules available for that purpose if I wanted to add it later.

Interestingly with my average speed over the past 450 miles the lipo battery voltage is settling around 11.3V or about 40%. Of course this means more than half the lipos capacity is unused and so is unnecessary extra weight.
