Can anyone help me ID these?

A few years ago I ran into a guy who wanted to get into planes and helis and bought out a guys entire collection. He didnt have any interest in the helis so he traded me a couple of kits with tons of parts...he had no idea what most of the parts went to and therefore neither do I. Anyone have any idea what these might go to?

It looks like something that would fit on the BSR. Although on the BSR those black balance blades are on top of the main rotors vs on bottom. Maybe for a Trex?

I've psoted these up over on helifreak and so far it seems to be the red one is to a Walkera UFlyS and the consensus seems to be the bigger blue one is likely to a Blade CP (or CP2 or CP Pro)...Anyone have any use for these? Theyre free + S&H I have no need for them.
