Hey all,

I'm building up the wing spars for my -B. Do we need these piloted bits for drilling the attach blocks and spar for mating or just when rigging the wings to the fuse?

Also, confirming these are the 2 needed to get the job done without having the hole wander or wallow out, misalign, etc,etc.
1/4 to 3/8 and then 3/8 to .0375 for the "tight fit hole"?
