I still have three IBU2 Pro boards left for sale, $160 plus $15 shipping to anywhere with a U.S. zip code. These boards have been thoroughly bench tested and are new boards, never before used.

I also have TPA amps for them, and I have quite a few of those, so if you already have an IBU2, base or pro (green board), and want to add an amp these are a great deal at $15. I believe the TPA is 15 watt, but not 100% certain. Perhaps one of you guys can enlighten me.

These boards are no longer in production, and I'm not sure they even still make the Ultimate. I've been told Ivano has disappeared so no one knows if IBUs will ever be made again. Once these last three are gone they're gone for good, which is why I kept a few for myself, and two of them will be used with a JS2 and a King Tiger, both IR battle tanks. Stay tuned.

This is an IBU2 Base, which is the same size as the Pro and looks very similar, but the Pro also has additional pins for channels 5 & 6, and also allows for servo operated traverse and elevation, just plug in the cables.
