Does the canard have problems with rain or bugs?
Many report that the nose wants to drop during rain or if the leading edge of the canard is covered with bugs. This is a characteristic of the GU canard that afflicts different DF aircraft to a greater or lesser extent, due to minute differences in construction between builders. Nobody has ever been known to suffer a crash as a result, but several pilots report being very scared of the reduction in lift when this occurs. It has sometimes required excessive speed on approach to landing or has resulted in “running out of elevator”. The problem can be solved quite simply by addition of vortex generators installed on top of the canard at the 50% chord line, spaced about 1.5 to 4 inches apart. It can also be solved by going to an entirely different canard shape, such as the LS-1, but thus far only 1 builder (Nate Rambo) has done this on a standard Dragonfly, and he cut up his canard when he retired from flying.
