RE: To maiden or Not to maiden... Tis' the question.
You probably won't have too much trouble... start off easy on the throws and remember the expo. I use an Airtronics radio, so when it came to to programming the radio for the Ultrastick, I skipped the sections for JR etc radios... big mistake! The manual lists the recomended throws in one place, but recomendations for expo settings are buried in the programming sections for each radio. So, I had no expo set up...my maiden flight was a little nerve wracking until I got the hang of it. Once I got it down, I went back into the manual and reread the WHOLE thing... there in the back were recomended expo settings...what a difference they made!
I'd suggest getting a more experienced pilot to at least stand behind you... an extra pair of hands on the trims might be handy!
Good luck!
