I"m printing the Structure, Structure rear, and Nacelle as I type. After these all I will need are the tail fin pieces. I'm using two Ender-3's for the job. The prop blade jobs went well with only one screww up on a pause. For me it seemed that M4 nuts fit into the pocket just about perfect. I tried an M5 and I could not insert the nut even with substantial force. I also havent read all of the comments so I may have missed a possible fastener size change or the instructions to file the nuts to fit. An M4 screw does slip nicely through the Crank piece. I'm hoping I missed a design tweak note. Like others here, I'm waiting for some of my components to arrive. I ordered the bearings from the UK on Sat. and I don't know when they will arriveto me in the U.S. All of the other componets should arrive by end of this week.... I tapped the various holes for their respective screw sizes and I wanted to use all machine screws. I hope to post a pic of the finished assembly soon. Thanks for doing the heavy lifting on this project.
