I must also add that the fuselage, spars and tail feathers were built over two years ago (thus the current infestation of hemlock doesn't effect my project) and they are still as straight and true as the day they were built. Although hemlock is approximately 10% heavier than sitka spruce, it only adds about 10 to at the most 15 lbs overall, and that includes the extra 22" added to the length of the fuselage. With the input received from the KR list, I am going with the largest split flaps possible and will continue to keep things simple and light, no fancy extras.
