Ya, done pretty good! cover it and start flying it. Don,t make the mistake of getting into the mindset that you have reinforce to point that it will survive another single point landing without a wing.

Next time on a similar repair don't do a butt joint of the sides like that but rather a scarf joint, the sides cut and joined with an angle preferrably around forty five degress. When you use thicker sides on a box fuse like that you can if you like forego the ply full length doublers.

If you really want to do a bit more rather than fiberglas just epoxy 1/32 ply joint doublers on the inside of the butt joint on the balsa only not where the ply is and these little doublers only need to be about a half inch wide. Just stripes over the balsa butt joint.
