Yeah, on the stock build it uses a skewer through the fuselage just ahead of the LE and behind the TE and the wing assembly is held on with rubberbands, along with the gear. I'm not so worried about being able to remove the assembly so I may permanently attach mine as well.
It is getting closer, just waiting on electronics right now and figuring out my finishing details.
Doing a little research on how to prep the FB with minwax, prepping for some basic pain scheme, and then the little details like struts, a pilot and what not. It's been a fun project and I've learned quite a bit about foam board. It's got a few defects here and there. My first bevels sucked and a few wrinkles in the board. But overall I'm happy with it.
