Don't go with the top wing off. Why would you buy a biplane and then try and fly it with the top wing off [&o] ? Oh well, to each it's own.

Anyway, as for the throws : The settings for the GP Christen Eagle should just work fine for yours, since it seems to have about the same dimentions. You can download the manual for GP eagle here : http://www.greatplanes.com/parts/index.html
Hope this helps.
