First build dedicated to freestyle, and first experience with KISS. I've fallen in love with my goby rigs, and they're my go-to beater/racers (damned things are virtually unbreakable), but I decided I wanted a smaller, lighter platform for acro. I like most everything about the frame hold the hs1177 mounting situation, it just seems so vulnerable out front like that, I'm sure I'll think up some sort of 3d printed mount to tuck it in better. Couldn't be happier with how the KISS hardware/software flies. It's a totally new frontier for me, so I'm still getting used to it, but so far so good. Everything just....works.
