smgfromny, a large number of things control the weight of a plane, its not just one thing thats a secret. For instance, changing the wheels to light flights saves about 1.5 oz, by using the light weight HS 525 servos I saved 1/2 oz per servo times 5, and because they are not "high torque high draw" I was able to use a 800mha battery insted of the 1100-1500 mha most use saving another once. I saved 3 oz by using a light weight motor mount. We saved another .5 oz with the pushrods, so in this short list we have saved over 1/2 pound and thats before we make any attempt to lighten the airframe. If you add your reciever and battery then subtract that 1/2 pound you to will end up at about 8 pounds wet, and by the way you can save as much as 2 onces in the selection of your reciever, you can save 1/4 once in the tail wheel alone. Its all in the little things that make them fly good. If your going to load up with digital servos, big batteries, larger fuel tanks, heavier landing gear, extra glass reinforced firewalls, extra epoxy fuel proofing, and so on you can't expect it to be light.
