well guys i builted my quest 50 and flew it today, and i was great! my quest has a ys fz63 four stroke with a 12x8 prop all hitec servos (hs425bb) which i only added 1 for the rudder at the tail, the elevator, servo under the main wing with a split push rod for both sides of the elevator.the CG was set for 125mm not what the sheet says. once in the air i just needed 3 clicks right and 2 click up elavator two have it flying smooth . the slow flight was just as good, and the throws were set low for now but roll rate even on low rates was very fast ,i did touch and go to see how she flies for landing and its very stable i even landed using flaprons WOW talk about smooth! the total weight is just under of 5lb and i luv this plane[
