Hi Everyone,
 I havent posted anything in quite sometime, but this model has proven to be a really nice flyer. It uses the dimensions of Bill Hannans "Boxy Bipe" , and then I made a twin pusher old time style frame , to make a pleasing fun model. I also made an under camber airfoil, and scalloped trailing edges from foam. The model weighs in at just over 7 oz, so it flies nice and slow. The video is a bit of sloppy flying , trying to film and fly at the same time is not so easy.  It is electric powered and rudder elevator control. It turms on a dime, and takes off and lands very nicely.

I like it; very interesting and nice to watch too. Thanks!

 (Can you tell us the span? I just looked up the Hannan Boxy Bipe dimensions and it says 10". Is it 7g rather than 7oz? Or is yours a much larger model? I find it surprisingly hard to tell from the vid, but it doesn't look as tiny as 10".)

Hi Pete-
 The model spans 30"- I forgot to mention that . The foam is dollar store foam board, with the paper peeled off. 7 oz is the correct weight, but with all that wing area, it just floats along. The motor and 8" prop I have on it is a bit under powered, but I just want it to do lazy circles. The power setting for most of the video is about 30-40%.
 I want to take better pics to show the model up close, the video is porr quality .

Thanks for the extra info, Jim. It's nice to see a model of such configuration flying floatily like that.
