Any time you get more than two RVers in a room, you'll probably be able to find something RV-related on which they disagree, perhaps violently. Variations of opinions about canopy styles, engines, taildraggers, what kind of prop is best . . . the list goes on and on. The disagreement about these topics and the resulting discussion that it generates isn't a negative part of the RV community - generally, it means that anyone that wants to can get multiple informed opinions on any given topic even if the people that they're listening to do not agree. Ideally, this helps people make informed decisions about the options on their airplane if they have the patience to listen to everyone else.
As great as that is, it makes life a bit intimidating for those that are new to the RV community. There aren't very many simple or clear-cut answers - any request for "what do you think about [some topic]" to an RV mailing list has the potential to touch off a firestorm of discussion. Given all that background, you can probably understand my hesitation in posting a message to the TVRVBG mailing list asking for opinions about whether or not I should attend the Aeroelectric workshop. To my surprise, everyone on the mailing list seemed to agree that I should go. Bob, according to everyone in the TVRVBG, really knows his stuff. Well, if I've found out the one thing that all RVers agree on, I certainly don't want to be left out. I'd better sign up.Even before I went to the workshop, though, something interesting happened to give me insight into the character of Bob. I discovered that the Aeroelectric website isn't secure, so typing in your credit card number over the web carries with it a certain amount of risk. I emailed Bob and explained that I didn't want to take this risk, but I still wanted to sign up for the class. Bob let me get away with putting in a fake credit card number and then promising to pay when I got to the class. I also wanted to get the book ahead of time, so I asked if he wanted me to send him a check. Well, a couple of days later two books (my dad and I were both planning to go) show up on the doorstep. I guess that's my answer - he didn't bother to wait for a check. That impresses the socks off of me as I haven't given him a check or valid credit card number yet.
After a quick hotel breakfast, we meandered into a room that was unequivocally the correct place to be, at least judging by the proliferation of airplane-themed shirts. After a well-organized registration, we all found our seats and Bob launched into a discussion of his airplane laws. Since these ideas formed the cornerstone for the whole course, I'll repeat them here:
These all sound like obvious ideas that we'd like to think are design criterion for all of the airplanes that we rent, but unfortunately this simply isn't true. Simply from a design perspective, some aircraft don't have fault-tolerance built into the system, but just depend on better parts that are less likely to break. Not only does this make the system more expensive, but because the part is probably still going to break eventually, the reliability of the system hasn't really been improved as much as it could be with a better design. Just from a purely practical standpoint, if you noticed that the alternator in the rental C-172 died twenty minutes into the flight, would you feel comfortable flying the rest of the way to the beach? How long would it take you to figure out that it wasn't working anymore?
In addition, everyone that has hung around airplanes (or the pilots that they own) for any appreciable length of time has heard horror stories of maintenance on certified airplanes. (In case you haven't, here's a sample.) A pretty healthy chunk of the "I learned about flying from that" stories that appear in aviation magazines would be much less exciting for both the readers of the magazine and the participants in the story if the setting involved well-planned electrical designs in airplanes that didn't have goofy things done to them when they were being maintained.
After Bob outlined his laws of airplane design, the rest of the course detailed the specifics of what you get when you apply those principles to an actual electrical system design. I'll run through the very high points of the class, but don't take this as even a summary of what Bob says. I'm not detailing any of the specifics here; for that you'll have to see his website, buy his book, or get on the Aeroelectric mailing list. In any case, the high points:
Before I attended this seminar, I had wondered about the relationship between the seminar and the book. If you had the book, is it still worth your time to go to the seminar? The answer is a definitive yes. Bob doesn't just teach straight from the textook in the class. What's convered in the class, in fact, is greatly dependent on what topics the participants in the class feel like asking about. There's a big advantage to reading the book ahead of time and coming prepared with questions about things that you don't understand or that you want Bob to explain in greater detail. The relationship bewteen the book and the seminar is such that you can read the book before or after the seminar and and still learn lots from both the seminar and the book. Obviously reading the book is much better than not doing either one at all, but even if you've read the book going to the seminar is still worth your time and attention. (Sam Buchannan has reviewed Aeroelectric book without the attached seminar. His review is worth a read. Sam, incidentally, is one of the people I have to thank for sending me to this workshop in the first place.)
It's amazing how many RVs out there are using wiring diagrams that have originated with Bob Nuckolls. I haven't met large numbers of RV folks (yet) but a healthy percentage of the builders I meet have either been to this class, read the book, or was influenced by someone who has.
Furthermore, it was neat to see how many folks in the class were building RVs - it was the majority of the people there. I got to meet Bobby Hester, who is the man behind of the first RV sites that I ran across when I first started looking for information on the RV-7/7A. Neat!

Conclusion: if you're building any kitplane, I strongly recommend you go to this workshop.
