whats the wingspan going to be?
and total weight without battery you think?

According to the magazine:
Wingspan: 35" (889mm)
Fuselage Length: 28" (711mm)
Wing Area: 1.7 sq ft. (0.16 sq. m)
All Up Weight: 12-25oz (595-709g)
Wing Loading: 12-15oz /sq. ft. (3.7 - 4.6kg / sq. m)

Of course individual results may vary!

I wonder what sort of thrust ratio you need for a high wing plane like this, I always hold my planes vertical and if it holds it's own weight at WOT then good if it climbs the better but I don't think that applies here, if that weight you gave is without battery then you add you batts at say 170g that's about 900g all up flying weight so with a SF prop 9x4.7 it will have maybe 800 g thrust which should cruise that Luton around nice and scale I reckon.. Sorry for flooding your thread mate I just like all this sort of power discussions
