I have to agree with da Rock on this one. IF there is a near miss that is below 1000 ft but over 400, both pilots are at fault. If a full scale pilot buzzes a field at under 400 ft, he is in violation of several regulations and needs to be grounded, plain and simple. At the one field, with a 250 ft ridge being adjacent, there is no question that the full sized pilot is in the wrong, REGARDLESS OF ANYONE BEING AT THE FIELD OR FLYING R/C. It's easy for a full sized pilot to call foul on an R/C but, at the same time, when will you see a full scale pilot admit that he/she was in the wrong? What's even harder is for some one on the ground to call them out due to lack of accurate height finding equipment.
