wow! great thread. A buddy and I just got back from E-fest in Champaign Illinois last weekend and we saw some incredible new stuff there. We have been into indoor aerobatics and foamies since "the beginning" and we are just now looking into breaking into the 6 oz super lightly loaded planes. We design and build our own, and usually shoot for 3 to 3.5 oz/sqft. We saw several 5 to 6 oz shockies and a few Nikitis Animals also at 6 oz. We were amazed at how much lighter (and better) they flew. I am now in the process of building the Icarus Shock Flier F3A. I plan on using the new Eflite park 300, a Thunderpower 2s or 3s 480mah pack, a gws dd 7x4 prop, (3) bluebird 303 servos, a castle creations berg microstamp reciever, and a castle creations pheonix 10 lite esc. I hope to come in at or around 6 oz with a basically stock airframe. If its heavy, I will rebuild the airframe from 3mm and push for 5 oz. I know its possible because Devon McGrath has done it. He had a stock f3a shocky and used strings instead of the supplied carbon for support. Awesome plane, awesome pilot. Jason Noll flew a new biplane design to victory in the "estyle" contest. See pic. It has a wingspan of around 40" and an auw of around 6-7 oz. Very similar to the aito.
