RE: Extra (260) wing loading
a 27% Extra is about 8 sq ft projected wing area and decent weight range is about 12-15 pounds.
My 22 lb model of EDGE (bout the same model really ) is 11.5 sq ft an that is lower end of envelope which once it his 25 lbs -all th shiny character is pretty well gone. It has 50 ++ lbs static thrust -
actually more -the prop- a Mejzlic , 27x10 spins over 6600 static and unloads to 7200 in level flight
at 4300 ft on a 70 degree day - you tell me what the thrust is. It is 'nuff.
