Wow! No wonder it came out at 19.5#. Go to 1 2300mAh A123 for the rx, 1500mAh 4.8V Nimh for the ignition and just one rx and that will be a good start. I'm all for redundancy in planes but the above set-up has served me well in all of my 30% planes without a lick of trouble.
Aeroworks' website lists the edge as being 17-18 pounds so with the set-up I described and possibly a non-cannister exhaust (unless you have noise restrictions at your field), you should be able to get to 18# easy. Go with a super light engine like a BME 58 Xtreme and you could get close to 17-17.5#. That would be a fantastic performer at that weight.
BTW, I used a 7955 on the rudder of my EF Extra, it was 18.5# and never suffered from rudder blowback or a lack of power. Get the weight down to 17-18lbs and the 7955 will be plenty of torque for any plane.
