As fate would have it, I snagged a couple of boards from a forum member last week. I picked up an AC commander and a mini commander with sound board. I think I will do the MC in one of my BEEPs first. I'm still debating swapping the pullmor's for can motors in the F3's. Waiting to here back from Frank at Timko.
I have @gunrunnerjohn 's post on doing a BEEP upgrade bookmarked. I will follow his lead.
