Yep, It's supposed to be a hobby forum but that has not stopped people from asking questions about items that could be considered sensitive. Anyone can figure out how to develop a plane that can fly long distances for extended periods of time but one of the items that stumps them is how to provide a reliable and adequate electrical source to power all that's needed for their purposes. It's happened before and people went to great lengths in describing how to do something without considering the who, what, and why of the people that were provided answers.

Pleased to hear that you accomplished your goal, but I still don't know who you are and what you do, and the intended purpose of your aircraft. Since you stated you are an engineer you should know all too well the reasons behind guarding some information. Too much is frequently given too freely.
