It's not a problem to fly a 10 oz airplane with a 30" wing span with a .051 if the wing is not to thick, like a typical 1/2A wing. But when you consider that the Jr flite streak wing is almost 1-1/2" thick, then you add a degree of difficulty which is not quite in the scope of 1/2 A power. I'm not saying it won't fly. I'm just saying I don't think it will fly well (And l suppose our definition of "WELL" may be different) with all the drag of that thick airfoil. But good luck to you. I hope you prove me wrong.
