Yes, the DH Hornet Moth can be a real "Bear "in conditions such as this, I have made myself a bit unpopular on occasions when I have declined to fly at airshows and "fly ins" when others are choosing to fly, so far have been lucky but if there is a grass surface available that's my first choice, and yes a tail wheel lock is worth fitting! its a very strange flying machine in high winds on a paved surface. The situation is made worse by the lack of a right hand throttle on most models, a failing we intend to fix this year.
