I'll put a bug in their ear for a comments section…
Monkeys are awesome! But I may be a little biased. With the many noobs coming to the event I think it would be a nice way to introduce them to some nitro and/or gasser safety and operation. Even if allowed, I'd assume the event to be 90% electric.
Running a flight line isn't that hard. I know it's their first event but with a congenial MC and safety officer, even part time, it goes pretty smoothly. I have an event at my place every couple years and while it's only 10-12 pilots, we mix electric, gassers, quads and gliders too. I'm sure this will be great!
Oh, the best thing you can bring to a flying event is common sense. Let the flight line know what you're going to do.
If you don't have common sense, don't worry, someone will give you an ear full of it in short order.
