I did some more work on the KFm3 wing today! My main achievement was getting the middle steps folded over and glued in place. I made it harder on myself by using Gorilla Glue with a 2 hr clamp time, so even with the weight benefits I might go back to hot glue for attaching the top steps.
I'm also going to try out ES9052 servos and a dual-band FrSky receiver in this build, which are both new components to me. I've actually had a Tandem X18 for a few years now, but I've only used a multiprotocol module in the add-on bay up until now since I had so many Spektrum receivers lying around!

Should be an exciting maiden when it's all done!
