The president of our club has one and it is a rush to see him fly it and i would wait for it.His is 12.5 lbs and has an os160 bisson muffler combo.Uses 4- 225 hi-tec servo,s to push the ailerons and 2-605s and 1-615mg to the tail surfaces all on pull pull.Used after market pull pull because DPs wire is pretty cheesy stuff.I wouldn,t use 225s but so far they are working great for him.
