Well, im still waitin for my replacement 4 in 1. I put Gregs 4 in 1 on my BCP and ran the antenna away from all other wires and thru a tube attached to the right skid. I fastened the tube to the carbon fiber support, just above the nipple of the skid. That gets is up off the ground, and because the way the ties are on, it makes the tube kinda swoop upward (nice). Test ran on a stool, then hovered and so far it seems fine. Maybe my whole problem was antenna placement, but it was just wrapped around the skid by the factory, or maybe the 4 in 1 was bad. I dunno, cause it acted up once with Gregs unit with the antenna wrapped around the skid. Weird...
