REFLECTOR: TR: Autopilot servos

do you have any pics of the roll trim cable and assy. for a SE RG thanx Jeff> From: cdwoolston at sbcglobal.net> To: reflector at tvbf.org> Date: Wed, 26 Mar 2008 04:47:23 -0700> Subject: Re: REFLECTOR: TR: Autopilot servos> > We mounted our BM servos in a very similar location and are flying.
