my Jae 45 G is hauling *****,faster than most 67/80,astonishing turning ability and any issue till now turning a 1657 mod.Last week just to see her limits removed my Picco 45 and installed a Mac 67 .......now I can say WOW! however I had to replace the rudder servo for a stronger one and put a longer blade rudder......I do inttend to run it in a saw event.Garson take a close look to your bend and check it out for some descolouring in the brass tube...maybe your S bend is not smooth enough and produced too much heat to have a break like this.
