 Sailplane Construction Project Session #30

This morning I measured the elevator deflection in the limited up position as shown below. There is unlimited down deflection capability due to the low hinge line location that I used. Specifically for those of you who have built and flown an R/C Assist Comet Sailplane, is a deflection of 18 degrees  for a two-sided elevator enough for control and maneuvering? I have heard that the Sailplane is sensitive to its elevator deflection. I can actually get more up deflection if required by doing more shaping to the top of the elevator's leading edges. Any feed back would be appreciated.....................Tandy
