Go to [link=http://www.tntlandinggear.com/store/shop/Product_List_Gear.htm]THIS[/link] page and scroll down to Fliton and check out the LG for the Fliton Edge 540. I think that will work, with some minor modification.

They also carry Graphtech CF gear, but I used it before (on a Fliton Extra) and it delaminated after less than one season of flying, so I don't recommend it.

Yes, the stock LG sucks, bigtime.

EDIT: Also I just realized they also have it for the Extra, and I think this is the larger sized Extra (not the Mini) so that should be just the ticket. I think the Edge 540 gear are straight, not curved.
