Don,

May I respectfully suggest that you go back to square one. What I mean is that the designs you mention, were done when light radios and batteries were not generally available. I saw SOME 1/2A designs call for the usual, 500mAh Ni-cad. Today, you can get 6 gram servos, 4 gram receivers and very small Nimh packs that are 1/4th the weight of Nicads.

Any plane with an ACE foam wing should not come in at over 20 ounces, in my opinion. No need. Weight is what creates the need for speed, just to keep the plane in the air. Add a heavy, OS .10 and it all just compounds.

Here, http://video.google.com/videoplay?do...94757217&hl=en you can see a Low Stik design that weighs just 16 ounces. This is exact scale to the original, no stretched wing etc. What if one took the original Eyeball plans, scaled them down, and used the ACE wing?

I realize that there's a real lack of good, 1/2A engines that throttle as well as the big pattern engines but it CAN be done. Someone just has to light a fire under CS's chair and get the ball rolling.

This http://www.youtube.com/watch?v=qHQhD...e=channel_page is what a CS AAN engine could do. At 19K on a 6 x 3 prop, 21 ounces of static thrust is developed. A 15 ounce airplane is amazing with 21 ounces pulling it. And when the time comes to slow her down, she WILL because of the low wing loading. Unfortunately, the day the video of the Low Stik was taken, it was very windy and I couldn't present any good, low speed aerobatics.
