A40-14S used in 50E Freestyle

I have a GW MX2 50E 57" wingspan. AUW = 5.3 lbs. CC ICE 75A, Blue lipo 5s5000mah. I switch between APCe 14x8.5 for faster flight and better hovering and a EMP 15x8 for a little more UMPH, but slower flight and shorter hovers. Works great and I get a 8 minute flight without any problems in 79 deg weather at my field (802 ft. asl). One of the support guys at ESPRIT helped me pick it out. He uses this setup on a 3DHS 59" SLICK. I have 25% remaining on my lipos when I land and even doing 50% hard flying, the lipos are barely warm. GREAT setup. Thanks, Esprit.
