I was able to set the pitch on one of the blades but when only I moved to the second I was only able to twist it about 10 degrees. We took the front cover off and swapped blades but it was the heal of the blade. I called Whirlwind and they said that this is not unusual as they bond the heal onto the blade and occasionally they come off oblong. We need to sand the heal down a bit for easier pivoting. That will happen tomorrow or next week.
