On the landing gear, it is held on by three bolts that screw into blind nuts. I put the blind nuts on the wrong side so you cant screw the landing gear to the fuse
I'm so glad I'm not the only one

I glued that bottom piece in with slow ca, and realized it maybe 15 minutes later. It was not quite set (but close), so I ripped it out by hand, getting ca all over my hands in the process..
I then turned the wood piece around so the blind nuts would face the right direction, and then spent 2 hours picking ca off of my fingers.
