Yeah, I read all that stuff about the BeeBrain and the BeeCore, but I haven't had a bit of trouble with the Makerfire. Bound DSM2 easily to my Devo 10 (tried it DSMX with the DXe and it wasn't as good), and haven't lost signal, had anything fall off, etc. It's heavier than the others (about the same as the BeeBrain), but it's been rock solid.
And I don't just fly it inside...it's hit MULTIPLE times on my concrete driveway while practicing power loops, and all it did was destroy my stock Inductrix frame (pre brace and reinforcement).
I've heard of people having some bind issues with some of the Spektrum's, but that's about it.
