Just in case you were wondering what the big deal about helis at RC airplane fields is. With RC airplanes and with the help of an instructor, other pilots can still fly their planes at the same time that a airplane student is flying. Other pilots can still taxi and take off or land while the new guy is training. New flyers with helis need to learn how to hover just over the runway. While doing that, the heli pilot ties up the runway for 10 or 15 minutes meanwhile making a smoky haze across the whole field. Airplane pilots don't want to get near that 3 or 4 foot spinning rotor to take off or land. When we are used to a 10 or 11" prop, to see that big rotor spinning away is rather disconcerting. I appreciate the skill level required to keep a helicopter in 1 piece but tying up a 500 foot runway is unfair to the rest of the pilots.
