RE: Spot On 50 Build log.
Be careful that you do not have the original version...just the Spot On 50. In the original version, the leading edge of the wing which mate onto the fuse is tapered. In the R and N versions, they squared this area off so the front of the wing has a square "butt" up to the fuse. Also, the belly pan on the original version had to be glued onto the wing, the N and R now have the two guide pins going into the fuse.
