My first GPSS died when a tx was turned on during approach, sniff sniff, and thats the one that broke the tailwheel prior to the interference crash. I went straight to the leaf spring setup on the replacement Stearman. That wire would be fine on a 40 size plane, but can't take the abuse of of a non perfect landing on the Stearman. I landed, was rolling, got hit by a cross gust, plane spun 90 deg's, tailwheel wire broke right below the lower hinge. That was the only time I ever had to walk to get this plane back to the truck. I don't have a kill switch yet, so it just sat there pointed into the wind idleing until I could get to it. Leafsprings rock !
