Hey guys,
I have the airframe finished, and motor, ESC, aileron servo and rudder servo installed of my third prototype of my own design. First design was a little large for my liking, so I scaled it down to a smaller version, with a few little tweaks such as larger ailerons (to scale). That one seemed a bit small, and the wings somehow got warped. The small one was a tad heavier than what I really wanted too.

Needless to say, I am on my third version which has an inch bigger wingspan, 1 1/2" longer fuse, wing chord is same, as well as distance between the wings. Also used carbon in the wings of this instead of thread.

Finished airframe weight is 2.15 oz. With motor, ESC, aileron and rudder servo installed it weighs 3.65 oz. Threw a heavy Eflite S75 (actual servo will be almost half the weight), and battery, prop, o-ring for prop saver on the scale as well and the scale reads 4.75 oz. I am figuring I will be at 5 ounces after I add all of the pushrods and control horns. Real happy with the estimated weight considering my smaller version weighed 5.3 oz, and this one is bigger.

Will post pics as soon as I get home from work after school.
