[:'(]I HAD THE SAME F-86..PUT A .60 OS IN IT. TIP STALLED ALSO.. NO MATTER WHERE THE CG WAS!! THE WING DOES NOT HAVE ENOUGH CAMBER.. REFLEX IS NOT THE ANSWER!!!! REFLEX MAKES YOUR PLANE THINK IT IS NOSE HEAVY..THATS WHY ,UP TRIM ,IS NEEDED AFTER THIS MOD.. WING FENCES ARE VERY GOOD.. BETTER YET, IS TO MAKE INBOAD WING LEADING EDGE MORE BLUNT...IT WILL STALL FIRST ,,STALL WILL BE STRAIGHT AHEAD. SWEPT WINGS ARE NOT AN EVIL THING!!! THEY JUST LOOK SCARY.. RD PS ---MY FLEW LIKE ,,KA-KA..
