Ihave often wondered this too. I am a Futaba owner but I went out and bought a cheap Spektrum DX-5 just for the micro BNFplanes from Horizon.

I did notice that Tower has a nice receiver-ready foam P-51 out now though that is in the same class as a lot of the Parkzone airplanes. Could BNF planes for Futaba be coming next? Who knows but it sure would be cool.
