I have the H-9 Edge and ran it last year on the Saito 150. I now have the ZDZ 40 installed and put the plane on a diet. It came in at 12lbs 12ozs. No wheel pants, no pilot, anything that could go went to keep it under 13lbs. I have a 1300mah NiCd pack for the servos and a 1100 mah pack for ignition. I could loose three more ozs by going to the 1650 MiMh for reciever power. With the Saito 150 and all the extras it was 12lbs 14ozs. No lead added with either set up.
