JohnW,
Thanks for that info. I know that the wing loading isnt going to be the only determining factor, this corsair has about a 74 inch span which isnt as big as i would like although it has a very long chord length, so i'll hope that its footprint in the air brings some efficiency to the equation to whatever weight it will come up to. Further looking into the manufacturers suggestion on motors they called for a G26 as an option, but for my intention i figured it wouldn't be as good as a larger motor. Surprisingly, the Zenoah G26 with stock muffler compared to this Brison 2.4 on a Bisson muffler has the Brison about 5 OZ. lighter which sounds promising insofar that if they say that weight of g26 will cut it then maybe im not too far of the mark after all. But of course anything i can do to make this bird lighter definately i'll do it.
