I changed out the brackets to allow the gear legs to flex without imparting a twist on the bracket/bolt assembly holding the gear legs to the bottom of the fuselage. The old system was flat faces with rubber underneath and there was a history of broken attachment bolts on the original setups. I also up-sized the bolts from an AN5C to AN6C. Going to the larger bolt reduced the amount of material in the bracket corners slightly, so we used 6013-T6 instead of the original 6061-T6. Sourced the 6013-T6 from McMaster-Carr (sku 9048K111). I have not installed them yet, I need to put a layup of glass to protect the aluminum brackets from the carbon first. But I test fit them on the legs and they seem to fit nicely.
