I remember from RP2 the frames, and blutricity. I loved them so much that I would have made an addon to Project Red to do so. I know that there are replacements for frames, just not blutricity. I would very much like you to add those.

To quote from MrTJP

Bluetricity will never be added.

I think there are plans for some sort of electricity system if it would be useful for the mod, will see what @MrTJP says.

credit where credit is due. blutricity was a genius name for a system that ran alongside a redstone focused mod

Not any time soon.
