I acquired a project (KR2S) that is about 40 - 50% complete; boat, spars, tail feathers etc. that was originally built to the plan's wing configuration. I would like to use the "new" airfoil and know that the spars need to be "taller".
What do you think is the best approach to doing this? The spars I have are extraordinarily well built... they are complete, including the "weep" holes for vacuum relief in the mahogany. Should I "cap" them fully, in other words over the mahogany facings on the spars, or should I just cap the main spruce spar material? Any input from anyone who has done this, or has built the new spars from scratch would be appreciated. Thanks Mark W. N952MW (res)
