RE: Installing seperates in CP
It would be nice if they'd let you trade toward the 3n1. Never hurts to ask.
I went to the LHS when I got a 2n1 and G90 saying I was going to put in a BCP. The heli 'guru' there didn't tell me it wouldn't work. It was some kindly soul on one of the forums who saved me from that one. So I'm doing my 'pay it forward' bit here!
